How to send personalized email to clients registered in my portal www.intrainternet.com using the information stored in our Database Oracle 8i automatically?


and we said...

This is a sample chapter from my book Expert One on One Oracle -- it describes how to send email from Oracle versions 816 and higher (the java only approach described about halfway through works in 815 and higher)

UTL_SMTP and sending mail

UTL_SMTP, introduced for the first time in Oracle 8.1.6, is an interface to the Simple Mail Transfer Protocol. It requires that you have an SMTP server in your network somewhere ? most sites I have been to have at least one SMTP server running as it is the most popular method for sending mail.

The UTL_SMTP package is best suited for sending small, text only emails from the database. While its API supports the sending of attachments and everything else ? it is left to you to actually encode the multi-part document ? for example turning binary attachments into mime-encoded documents.

We've already seen how to use UTL_SMTP in the DBMS_JOB section where we made it 'apparently' execute faster by doing it asynchronously. In this section we?ll revisit that example, build upon it ? adding additional functionality. We will also look at an alternative to UTL_SMTP that provides somewhat much more functionality ? including the ability to easily send attachments with the email. Since SMTP is a very low level protocol, we'll reuse existing public domain code to get an SMTP interface at much higher level ? and we'll get it with very little code.

UTL_SMTP ? a larger example

In the DBMS_JOB section, we explored how to make sending email using UTL_SMTP appear to execute faster. We also made email transactional in nature in that section ? if you rollback the email does not get sent, if you commit ? out it goes. I highly recommend the use of DBMS_JOB as a layer on your emails routines for these reasons. In that section, the example UTL_SMTP routine we used was:

tkyte@TKYTE816> create or replace
2 PROCEDURE send_mail (p_sender IN VARCHAR2,
3 p_recipient IN VARCHAR2,
4 p_message IN VARCHAR2)
5 as
6 l_mailhost VARCHAR2(255) := 'aria.us.oracle.com';
7 l_mail_conn utl_smtp.connection;
8 BEGIN
9 l_mail_conn := utl_smtp.open_connection(l_mailhost, 25);
10 utl_smtp.helo(l_mail_conn, l_mailhost);
11 utl_smtp.mail(l_mail_conn, p_sender);
12 utl_smtp.rcpt(l_mail_conn, p_recipient);
13 utl_smtp.open_data(l_mail_conn );
14 utl_smtp.write_data(l_mail_conn, p_message);
15 utl_smtp.close_data(l_mail_conn );
16 utl_smtp.quit(l_mail_conn);
17 end;
18 /
Procedure created.

tkyte@TKYTE816> begin
2 send_mail( 'thomas.kyte@oracle.com',
3 'tkyte@oracle.com',
4 'Hello Tom' );
5 end;
6 /

PL/SQL procedure successfully completed.

That works OK but is very limited in nature. It sends email to exactly one recipient, you cannot CC or BCC anyone, you cannot setup a subject -- the email always arrives with a ?blank? subject line. We would like to support more options with this package.

A full discussion of all of the possibilities with UTL_SMTP would require in depth knowledge of the SMTP protocol itself ? something that is outside the scope of this book. Readers interested in all of the opportunities available with SMTP should review RFC812 ? which is the description of SMTP. This is available online at </code> http://www.faqs.org/rfcs/rfc821.html
 Below, I will simply present how to send an email using UTL_SMTP that supports:

o Multiple ?to? recipients
o Multiple ?cc? recipients
o Multiple ?bcc? recipients
o A single body of up to 32k in size
o A subject line
o A descriptive ?from? line (instead of showing just the email address as the ?from? in the email client)

A specification for a PLSQL package that supports this might look like the following.  In here, we define an array type to allow for a caller to easily send a list of recipients as well as provide the external specification of the PLSQL routine we will be implementing:

tkyte@TKYTE816> create or replace package mail_pkg
  2  as
  3          type array is table of varchar2(255);
  4
  5          procedure send( p_sender_email in varchar2,
  6                          p_from         in varchar2,
  7                          p_to           in array default array(),
  8                          p_cc           in array default array(),
  9                          p_bcc          in array default array(),
 10                          p_subject      in varchar2,
 11                          p_body         in long );
 12  end;
 13  /
Package created.

The package body for this implementation is relatively straightforward ? if understand just enough of the SMTP protocol and what an email looks like (how email clients get the From, To, CC and so on).  Before we look at the code, we?ll look at what an email might actually look like. Consider the following ASCII text:

Date: 13 May 01 12:33:22
From: Oracle Database Account <tkyte@us.oracle.com>
Subject: This is a subject
To: tkyte@us.oracle.com, thomas.kyte@oracle.com
Cc: tkyte@oracle.com

Hello Tom, this is the mail you need

That is what you would transmit as the body of the email using UTL_SMTP to have the email client set the From, Subject, and so on.  There are no SMTP commands to do that magic, rather, this header information is placed right in the body of the email itself ? separated from the text of the email by a blank line.  Once we understand that ? sending an email with all of the options we need is pretty easy.  The only thing we need to understand beyond that is that in order to send the email to more then one recipient, we simply call UTL_SMTP.RCPT more then once ? with different names.  That?s all of the information we need to know then to send an email.

So, here is the package body.  We start with a couple of constants and globals.  You will of course need to change the g_mailhost to be the name of a server you have access to, Aria is my machine inside of Oracle ? you will not be able to access that:

tkyte@TKYTE816> create or replace package body mail_pkg
  2  as
  3
  4  g_crlf        char(2) default chr(13)||chr(10);
  5  g_mail_conn   utl_smtp.connection;
  6  g_mailhost    varchar2(255) := 'aria.us.oracle.com';
  7

Next we have an internal (unpublished) function to send an email to many recipients ? it in effect addresses the email.  At the same time, it builds the ?To:? or ?Cc:? lines that we?ll eventually send as part of the email itself and returns that formatted string.  It was implemented as a separate function since we need to do this separately for the To, CC, and BCC lists:

  8  function address_email( p_string in varchar2,
  9                          p_recipients in array ) return varchar2
 10  is
 11      l_recipients long;
 12  begin
 13     for i in 1 .. p_recipients.count
 14     loop
 15        utl_smtp.rcpt(g_mail_conn, p_recipients(i) );
 16        if ( l_recipients is null )
 17        then
 18            l_recipients := p_string || p_recipients(i) ;
 19        else
 20            l_recipients := l_recipients || ', ' || p_recipients(i);
 21        end if;
 22     end loop;
 23     return l_recipients;
 24  end;
 25
 26

Now we have the implementation of our published function ? the one people will actually call to send mail.  It starts with an internal procedure writeData that is used to simplify the sending of the email headers (the To:, From:, Subject: records).  If the header record is NOT NULL, this routine will use the appropriate UTL_SMTP call to send it ? along with the necessary end of line marker (the carriage return/line feed):

 27  procedure send( p_sender_email in varchar2,
 28                  p_from         in varchar2 default NULL,
 29                  p_to           in array default array(),
 30                  p_cc           in array default array(),
 31                  p_bcc          in array default array(),
 32                  p_subject      in varchar2 default NULL,
 33                  p_body         in long  default NULL )
 34  is
 35      l_to_list   long;
 36      l_cc_list   long;
 37      l_bcc_list  long;
 38      l_date      varchar2(255) default
 39                  to_char( SYSDATE, 'dd Mon yy hh24:mi:ss' );
 40
 41      procedure writeData( p_text in varchar2 )
 42      as
 43      begin
 44          if ( p_text is not null )
 45          then
 46              utl_smtp.write_data( g_mail_conn, p_text || g_crlf );
 47          end if;
 48      end;

Now we are ready to actually send the mai.  This part is not very different from the very simple routine we started with.  It begins in exactly the same fashion ? by connecting to the SMTP server and starting a session:

 49  begin
 50      g_mail_conn := utl_smtp.open_connection(g_mailhost, 25);
 51
 52      utl_smtp.helo(g_mail_conn, g_mailhost);
 53      utl_smtp.mail(g_mail_conn, p_sender_email);
 54

Here is where it differs, instead of calling UTL_SMTP.RCPT once ? it uses are address_email function to call it potentially many times, building the ?To:? and ?Cc:? list for us as well.  It builds the BCC list but we won?t actually send that (we don?t want the recipients to see that list!)

 55      l_to_list  := address_email( 'To: ', p_to );
 56      l_cc_list  := address_email( 'Cc: ', p_cc );
 57      l_bcc_list := address_email( 'Bcc: ', p_bcc );
 58

Now, we use the OPEN_DATA call to start sending the body of the email.  The code on lines 61 through 68 generates the header section of data.  Line 69 sends the body of the email (the contents of the email) and line 70 terminates the email for us. 

 59      utl_smtp.open_data(g_mail_conn );
 60
 61      writeData( 'Date: ' || l_date );
 62      writeData( 'From: ' || nvl( p_from, p_sender_email ) );
 63      writeData( 'Subject: ' || nvl( p_subject, '(no subject)' ) );
 64
 65      writeData( l_to_list );
 66      writeData( l_cc_list );
 67
 68      utl_smtp.write_data( g_mail_conn, '' || g_crlf );
 69      utl_smtp.write_data(g_mail_conn, p_body );
 70      utl_smtp.close_data(g_mail_conn );
 71      utl_smtp.quit(g_mail_conn);
 72  end;
 73
 74
 75  end;
 76  /
Package body created.

And that?s it, now since I have many email addresses (tkyte@us.oracle.com, tkyte@oracle.com, thomas.kyte@oracle.com, utility@aria.us.oracle.com) I can test this API like this:

tkyte@TKYTE816> begin
  2      mail_pkg.send
  3      ( p_sender_email => 'tkyte@us.oracle.com',
  4        p_from => 'Oracle Database Account <tkyte@us.oracle.com>',
  5        p_to => mail_pkg.array( 'tkyte@us.oracle.com',
                                           'thomas.kyte@oracle.com' ),
  6        p_cc => mail_pkg.array( 'tkyte@oracle.com' ),
  7        p_bcc => mail_pkg.array( 'utility@aria.us.oracle.com' ),
  8        p_subject => 'This is a subject',
  9        p_body => 'Hello Tom, this is the mail you need' );
 10  end;
 11  /

PL/SQL procedure successfully completed.

And that call is exactly what generated the ASCII text:

Date: 13 May 01 12:33:22
From: Oracle Database Account <tkyte@us.oracle.com>
Subject: This is a subject
To: tkyte@us.oracle.com, thomas.kyte@oracle.com
Cc: tkyte@oracle.com

Hello Tom, this is the mail you need

We saw above ? that is what got sent to all of those recipients ? including utility@aria.us.oracle.com, although we cannot see that recipient since it was bcc?ed.

That covers most of the typical uses of the UTL_SMTP supplied package.  Above I did say it is capable of sending email with attachments and such but that would require an inordinate amount of effort on our part.  We would have to:

o Learn how to format a multi-part mime encoded document, no small feat
o Base-64 encode binary data (or use some equivalent encoding technique such as uuencoding, binhex, and so on)

That would be (conservatively) a couple of hundred, if not thousands of lines of PL/SQL code.  Rather then do that, I will suggest that you use the already written and very robust JavaMail API as described below.

<b>
Loading and using the JavaMail API
</b>

In order to use the UTL_SMTP package, you must already have a Java enabled database in Oracle8i.  This is because UTL_SMTP relies on UTL_TCP and UTL_TCP in turn is built on Java functions. (Remember, if you don't have a Java enabled database you can use UTL_HTTP as described above to send simple emails). So, if you are able to use UTL_SMTP, you must have a Java enabled database, we can go to the Sun website and download their JavaMail API. This will give us the ability to send much more complicated emails from the database; including attachments. The following is based on work performed by a coworker of mine, Mark Piermarini who helps me out with lots of my Java issues.

If you go to 
http://java.sun.com/products/javamail/index.html,
you'll be able to download their JavaMail API. The download you get will consist of a couple of hundred files; only one of which we are interested in. After you download the JavaMail API ? make sure also to get their the JavaBeansTM Activation Framework extension or JAF (javax.activation). This is needed to run the JavaMail API package.

After you have downloaded these two sets of files ? you will need to extract mail.jar from the JavaMail APIdownload and activation.jar from the JAF download. This is all you will need from this ? feel free to read through the documentation, there is a lot of functionality in there we are not using, we are just using the 'send an email' part of the API. The API includes functions for receiving mail as well from IMAP, POP, and other sources.

We will need to load the mail.jar and activation.jar into the database using loadjava but before we can do that we must repackage them. These jar files are compressed in a format that is not understood by the database byte code interpreter. You need to 'unjar' and 'rejar' them without compression or use a tool such as WinZip to 'rejar' them into a zip file. What I did on Windows 2000 was:

1. Used WinZip to extract the contents of mail.jar into my c:\temp\mail directory
2. Used WinZip to create a new archive c:\temp\mail8i.zip
3. Put the contents of c:\temp\mail\*.* including subdirectories into this new archive

I did the same thing for activation.jar ? only replacing mail with activation in the above steps. Now we are ready to load these zip (or jar files, whatever you named them) into the database. These need to be loaded using the SYS user since they have 'protected' Java packages that regular users cannot upload. We will use the commands:

loadjava -u sys/manager -o -r -v -f -noverify -synonym -g public mail8i.zip
loadjava -u sys/manager -o -r -v -f -noverify -synonym -g public activation8i.zip

Where:

o -u sys/manager: is the userid and password for your SYS account.  As stated previously, some of the packages are protected and must be loaded as SYS
o -o: is shorthand for ?oci8, I am using the oci8 driver. You could use the thin driver as well but you'll need to modify the command to do so
o -r: is short for ?resolve. This will resolve all external references in the loaded classes helping to verify that the loaded java classes will be able to function after we load them
o -v: is short for ?verbose.  This gives us something to do while loadjava is running. We can see it work through each step of its process.
o -f: is short for ?force. This isn't necessary on the first load but is OK to use. If you try a loadjava and hit an error, you can correct it, and reload ? then you would either need to use the dropjava command to drop the jar file from the database or use ?force. Using ?force just makes it easier for us.
o -noverify: does not attempt to verify the bytecode. You must be granted oracle.aurora.security.JServerPermission(Verifier) to execute this option. In addition, this option must be used in conjunction with -r. SYS has this privilege. This is needed because the bytecode verifier will flag some issues with the mail.jar file and this works around that issue.
o -synonym: creates public synonyms for these classes. Since we will not install the mail java code we write as SYS, this allows us to 'see' the SYS loaded java classes.
o -g public: grants execute on these loaded classes to PUBLIC. If this is not desirable, change the ?g to be just the user you want to create the 'send mail' routines in, for example -g UTILITY_ACCT.
You can find out more about loadjava and the above options in the Oracle8I Java Developers Guide.

After these packages are loaded, we are ready to create a Java stored procedure to actually send the mail. This procedure will act as a thin layer on top of the JavaMail API and will let us ultimately write a PL/SQL binding layer with the following spec:

tkyte@TKYTE816> desc send
FUNCTION send RETURNS NUMBER
 Argument Name                  Type                    In/Out Default?
 ------------------------------ ----------------------- ------ --------
 P_FROM                         VARCHAR2                IN
 P_TO                           VARCHAR2                IN
 P_CC                           VARCHAR2                IN
 P_BCC                          VARCHAR2                IN
 P_SUBJECT                      VARCHAR2                IN
 P_BODY                         VARCHAR2                IN
 P_SMTP_HOST                    VARCHAR2                IN
 P_ATTACHMENT_DATA              BLOB                    IN
 P_ATTACHMENT_TYPE              VARCHAR2                IN
 P_ATTACHMENT_FILE_NAME         VARCHAR2                IN

This function will give us the ability to use CC's and BCC's and send an attachment. It is left as an exercise for the reader to implement passing arrays of BLOBs or overloading this to support CLOB or BFILE types for attachments as well.

The Java stored procedure we will create follows. It uses the basic functionality of the JavaMail API class and is relatively straightforward. Again, we are not going into all of the uses of the JavaMail API (that could be a book in itself), just the basics here.  The ?mail? class below has a single method ?send?.  This is the method we will use to send a message.  As it is implemented, it returns the number 1 if it is successful in sending the meial and a 0 otherwise.  This implementation is very basic ? it could be much more sophisticated, providing support for many attachment types (CLOBS, BFILES, LONGS and so on).  It could also be modified to report back to the caller the exact error received from SMTP such as ?invalid recipient, no transport, and so on.

 22                              String cc,
 23                              String bcc,
 24                              String subject,

 28                              String attachmentType,
 29                              String attachmentFileName)

The above argument list matches up with the SQL call specification we outlined above ? the arguments are mostly self explanatory.  The two that might need some clarification are the attachmentType and the attachmentFileName.  The attachmentType should be a MIME (Multi-purpose Internet Mail Extensions) type ? as you might be familiar with from HTML documents.  The MIME type of a GIF image for example is ?image/gif?, the mime type of a plain text document would be ?text/plain?, an HTML attachment would be ?text/html? and so on.  The attachmentFileName in this example is NOT the name of an existing OS file that would be attached but rather the filename of the attachment in the email itself ? what the recipient of this email will see the name of the attachment as.  The actual attachment is the oracle.sql.BLOB that is sent to this routine.  Now, onto the body of the code.  We begin by setting the session property ?mail.smtp.host? to the name of the SMTP host the caller sent to us ? the JavaMail API reads this value when deciding what SMTP server to connect to:

 30    {
 31      int rc = 0;
 32
 33      try
 34      {
 35        Properties props = System.getProperties();
 36        props.put("mail.smtp.host", SMTPHost);
 37        Message msg =
 38          new MimeMessage(Session.getDefaultInstance(props, null));
 39

Next, we set up the email headers.  This part tells the JavaMail API who the message if from, who to send it to, who to send a ?carbon copy? (cc) or ?blind carbon copy? (bcc), what the subject of the email is and what date should be associated with the email:

 40       msg.setFrom(new InternetAddress(from));
 41
 42       if (to != null && to.length() > 0)
 43          msg.setRecipients(Message.RecipientType.TO,
 44                            InternetAddress.parse(to, false));
 45
 46       if (cc != null && cc.length() > 0)
 47          msg.setRecipients(Message.RecipientType.CC,
 48                            InternetAddress.parse(cc, false));
 49
 50       if (bcc != null && bcc.length() > 0)
 51          msg.setRecipients(Message.RecipientType.BCC,
 52                            InternetAddress.parse(bcc, false));
 53
 54       if ( subject != null && subject.length() > 0 )
 55            msg.setSubject(subject);
 56       else msg.setSubject("(no subject)");
 57
 58        msg.setSentDate(new Date());
 59

Next, we use one of two methods to send an email.  If the attachmentData argument is not null, then we will MIME encode the email ? a standard that supports the sending of attachments and other multi-part documents.  We do this by setting up multiple MIME body parts ? in this case two of them, one for the body of the email (the text) and the other for the attachment itself.  Lines 76 through 78 need a little additional explanation.  They are how we can send an email via a BLOB.  The JavaMail API doesn?t understand the oracle.sql.BLOB type natively (it is after all a generic API).  In order to send the BLOB attachment, we must provide a method for the JavaMail API to get at the BLOB data.  We accomplish that by creating our own DataHandler ? a class with an interface that the JavaMail API understands how to call in order to get data to populate the attachment.  This class (BLOBDataHandler) is implemented by us as a nested class below.

 60        if (attachmentData != null)
 61        {
 62          MimeBodyPart mbp1 = new MimeBodyPart();
 63          mbp1.setText((body != null ? body : ""));
 64          mbp1.setDisposition(Part.INLINE);
 65
 66          MimeBodyPart mbp2 = new MimeBodyPart();
 67          String type =
 68              (attachmentType != null ? attachmentType : dftMime);
 69
 70          String fileName = (attachmentFileName != null ?
 71                             attachmentFileName : dftName);
 72
 73          mbp2.setDisposition(Part.ATTACHMENT);
 74          mbp2.setFileName(fileName);
 75
 76          mbp2.setDataHandler(new
 77             DataHandler(new BLOBDataSource(attachmentData, type))
 78          );
 79
 80          MimeMultipart mp = new MimeMultipart();
 81          mp.addBodyPart(mbp1);
 82          mp.addBodyPart(mbp2);
 83          msg.setContent(mp);
 84        }

If the email does not have an attachment ? setting the body of the email is accomplished very simply via the single call to setText:

 85        else
 86        {
 87          msg.setText((body != null ? body : ""));
 88        }
 89        Transport.send(msg);
 90        rc = 1;
 91      } catch (Exception e)
 92      {
 93        e.printStackTrace();
 94        rc = 0;
 95      } finally
 96      {
 97        return new oracle.sql.NUMBER(rc);
 98      }
 99    }
100

Now for our nested class BLOBDataSource.  It simply provides a generic interface for the JavaMail API to access our oracle.sql.BLOB type.  It is very straightforward in its implementation:

101    // Nested class that implements a DataSource.
102    static class BLOBDataSource implements DataSource
103    {
104      private BLOB   data;
105      private String type;
106
107      BLOBDataSource(BLOB data, String type)
108      {
109          this.type = type;
110          this.data = data;
111      }
112
113      public InputStream getInputStream() throws IOException
114      {
115        try
116        {
117          if(data == null)
118            throw new IOException("No data.");
119
120          return data.getBinaryStream();
121        } catch(SQLException e)
122        {
123          throw new
124          IOException("Cannot get binary input stream from BLOB.");
125        }
126      }
127
128      public OutputStream getOutputStream() throws IOException
129      {
130        throw new IOException("Cannot do this.");
131      }
132
133      public String getContentType()
134      {
135        return type;
136      }
137
138      public String getName()
139      {
140        return "BLOBDataSource";
141      }
142    }
143  }
144  /

Java created.

Now that we have the Java class created for PL/SQL to bind to, we need to create that binding routine to map the PL/SQL types to their Java Types and to bind the PL/SQL routine to this Java class. That is simply:

tkyte@TKYTE816> create or replace function send(
  2      p_from                  in varchar2,
  3      p_to                    in varchar2,
  4      p_cc                    in varchar2,
  5      p_bcc                   in varchar2,
  6      p_subject               in varchar2,
  7      p_body                  in varchar2,
  8      p_smtp_host             in varchar2,
  9      p_attachment_data       in blob,
 10      p_attachment_type       in varchar2,
 11      p_attachment_file_name  in varchar2) return number
 12  as
 13  language java name 'mail.send( java.lang.String,
 14                                 java.lang.String,
 15                                 java.lang.String,
 16                                 java.lang.String,
 17                                 java.lang.String,
 18                                 java.lang.String,
 19                                 java.lang.String,
 20                                 oracle.sql.BLOB,
 21                                 java.lang.String,
 22                                 java.lang.String
 23                               ) return oracle.sql.NUMBER';
 24  /

Function created.

Now, the very last thing we must do before using this is to ensure our user (the owner of the above "mail" class and "send" stored procedure) has sufficient privileges to execute the routine. Those would be the following:

sys@TKYTE816> begin
  2    dbms_java.grant_permission(
  3       grantee => 'TKYTE',
  4       permission_type => 'java.util.PropertyPermission',
  5       permission_name => '*',
  6       permission_action => 'read,write'
  7    );
  8    dbms_java.grant_permission(
  9       grantee => 'TKYTE',
 10       permission_type => 'java.net.SocketPermission',
 11       permission_name => '*',
 12       permission_action => 'connect,resolve'
 13    );
 14  end;
 15  /

PL/SQL procedure successfully completed.

Note that in the grant on java.net.SocketPermission, I used a wildcard in the permission_name. This allows TKYTE to connect to and resolve ANY host. Technically, we could put in there just the name of the SMTP sever we will be using.  That would be the minimal grant we needed. This is needed in order to resolve the hostname of our SMTP host and then connect to it.  The other permission, java.util.PropertyPermission, is needed in order to set the mail.smtp.host in our sessions properties.

Now we are ready to test. I reused some code from the DBMS_LOB section where we had a routine "load_a_file". I modified that and the DEMO table to have a BLOB column instead of a CLOB and loaded the mail8i.zip file we loaded in as a class into this demo table. Now I can use the following PL/SQL block to send it to myself as an attachment in an email from the database:

tkyte@TKYTE816> set serveroutput on size 1000000
tkyte@TKYTE816> exec dbms_java.set_output( 1000000 )

tkyte@TKYTE816> declare
  2    ret_code number;
  3  begin
  4    for i in (select theBlob from demo )
  5    loop
  6      ret_code := send(
  7                    p_from => 'tkyte@oracle.com',
  8                    p_to => 'tkyte@oracle.com',
  9                    p_cc => NULL,
 10                    p_bcc => NULL,
 11                    p_subject => 'Use the attached Zip file',
 12                    p_body => 'to send email with attachments....',
 13                    p_smtp_host => 'aria.us.oracle.com',
 14                    p_attachment_data => i.theBlob,
 15                    p_attachment_type => 'application/winzip',
 16                    p_attachment_file_name => 'mail8i.zip');
 17      if ret_code = 1 then
 18        dbms_output.put_line ('Successfully sent message...');
 19      else
 20        dbms_output.put_line ('Failed to send message...');
 21      end if;
 22    end loop;
 23  end;
 24  /
Successfully sent message...

PL/SQL procedure successfully completed.

You definitely want to set serverouput on and call the DBMS_JAVA.SET_OUTPUT routine on when testing this. This is because the exception is being printed by the Java stored procedure to System.out and by default that will go into a trace file on the server. If you want to see any errors in your SQLPlus session, you need to make these two settings. It will be very useful for debugging purposes!

<b>Summary</b>

In this section, we briefly reviewed the existing UTL_SMTP package.  Here we saw how to send emails to multiple recipients with a custom From: and Subject: header.  That should satisfy most peoples needs for sending email from the database. UTL_SMTP is good for sending simple text only emails but sending attachments or complex emai

Any suggestions? Or can you send me the re-jar'ed files and tell me where to get them.

Thanks,

Very good solution.

Excellently simplified solution

Akthar &amp; Kamalanathan - akthar.aj@ebridgex.com, July 26, 2001 - 5:52 am UTC

Neatly done with correct step, We would like to comment(checklist) something on positive sense ,
1. First to start with Check whether JVM for Oracle is installed, else run $oracle_home/javavm/install/initjvm.sql
2.Set(add) classpath $oracle_home/sqlj/lib/translator.zip
3.Follow the steps 1,2,3,4 given in the TOM's response with only change on step 4 you have to "desc send" not "desc mail". Step 5 make changes to suit your SMTP HOST.
4. You are done ...

Wish u Happy Oracle Mailing on 8.1.5.

Can I send email from D2K?

Sazzadur Rahman Tusar, January 28, 2002 - 11:07 pm UTC

I tried to send email from D2K but it failed.
I used OLE2.OBJ_TYPE as per your writings earlier, but it shows error, because OBJ_TYPE is not a procedure.
How it will be solved?
Would you please give me a solution?

you did not use a valid mail host in your send_mail routine. You are getting an error back from the "smtp" server (which isn't an smtp server) saying "i'm not available"

you did change:

5 as
6 l_mailhost VARCHAR2(255) := 'aria.us.oracle.com';
7 l_mail_conn utl_smtp.connection;
8 BEGIN

to have a hostname that would be valid for you right?



Great it works!!

Hi,

thanks for locating the error for me. Indeed, there was an error in the address.

sorry for any inconveniences.

TOM you are simply GREAT..!!!!!

Manoj Bajaj, February 18, 2002 - 9:33 pm UTC

Tom this mail routine we are using it since last few months and is running and mailing well. thank u so much.

I have made some changes to this routine to send multiple files / attachments ..ofcourse by not passing blob array ..(as did not know I to do that ..!!!) but by reading files in java program..! I would like to send u the source.

Mean I would also like to know one thing what decides total attachment size to be sent in one mail. In one database sch I can send attachments of 1MB whereas in other I'm restricted to 6 MB..I'm cannot find what is restricting me from sending bigger attachments...Any clue...unix or oracle parameter as these two are on diff unix servers but SMTP is same.

Once again Many thanks for ur continuous support.

Error handling

Sudip Sarkar, February 21, 2002 - 10:01 am UTC

Hi Thomas,
Your solutions are simply great. I have used your code to send email. But I facing a peculiar problem. Once there was a problem in the SMTP server and it stopped responding, now at that moment I fired a mail from the database. The result was that my sesion got hung.
Is there any way of trapping the error.

manoj, February 25, 2002 - 12:46 am UTC

Hi Check the trace file generated in user_dump_dest ..directory on your server u may get the exacty nature of problem there.

Bob Yexley, February 25, 2002 - 1:40 pm UTC

Thanks so much for this solution. If I can get it working, it will be a HUGE help and solution for our needs.

I am trying to follow the instructions laid out here, and did everything they said to do, but am having problems with the loadjava command for mail8i.zip. When I ran it, it loaded everything fine, but ran into problems when trying to resolve referenced objects. I'm getting ORA-29534, and the result is 45 unresolved object references after the load. The loading of the activation8i.zip worked great, no problems at all, but had problems with SOME of the objects in mail8i.zip. Here is one example of the errors that I am getting:

show me a cut and paste of your loadjava command.

Response to followup

Bob Yexley, February 26, 2002 - 1:24 pm UTC

My loadjava command was as follows:

Tom Kyte
February 26, 2002 - 5:14 pm UTC

Can you reload both the activation and mail ZIP files using another user? This will facilitate debugging and we can use it to check the resolver for any problems. Also, add '-debug' to your loadjava commands and send that output to mbpierma@us.oracle.com.

this should not be done over the network -- the file you are loading must be the one on the server anyway so... don't use the network.

Sending e-mail! -- Oracle 8i specific response

Harvey, February 26, 2002 - 4:03 pm UTC

Do we need to do the same things for Oracle9i as you described in this detailed instruction? If it is different, could you explain it also in detail?

Thanks a lot!

Harvey

Tom Kyte
February 26, 2002 - 4:49 pm UTC

should work in 9i, haven't loaded it up myself as yet but the steps would basically be the same (you don't have to use sys and probably won't be able to use sys in most cases in 9i, that would be different)

yes, you would need to do this in 9i if you wanted to send email with attachments.

I cant get it work!

I have two instances running on the same machine,
I have opened the telnet session on box where my database is, and trying to load plsql.jar by issuing the following command.
(RCIS_DEV)$ loadjava -user sys/change_on_install@rcis_dvl plsql.jar
And getting this error..

I checked my $ORACLE_SID which is set to rcis_dvl

You should log in as the Oracle software owner.

You should verify your oracle_home and oracle_sid

You should verify that you can then:

BCC List

Chris Soza, April 03, 2002 - 11:25 am UTC

Tom,

In your pl/sql solution if bcc list is not written out with writeData, can you explain how it will work ?

Thanks,

Chris

Tom Kyte
April 03, 2002 - 4:03 pm UTC

because this:

15 utl_smtp.rcpt(g_mail_conn, p_recipients(i) );



does the actual sending, the writing of the CC and TO list is only for display -- the call to writedata with that doesn't affect WHO the email is actually sent to -- just what the email client displays.

mail.jar and activation.jar

Chris Soza, April 04, 2002 - 9:31 am UTC

Tom

I downloaded the javamail package as per your note. However, in the archive there is no activation.jar file. Any idea how I can get this ?. I downloaded the 1.2 version.

Also, thanks for explaining how bcc list works.

Tom Kyte
April 04, 2002 - 1:23 pm UTC

contact your email guys/network guys.

the server you are attempting to use is not set up to relay, this is NOT an oracle issue, not a UTL_SMTP issue, it is a SMTP configuration issue. You are probably using the WRONG mailhost as it's not setup to relay (anti-spamming defense)

email body size

manohar, April 04, 2002 - 3:43 pm UTC

tom,

is there a limit on the email body size like you mentioned in your answer as 32k only.

please reply.

thanks

Tom Kyte
April 04, 2002 - 3:57 pm UTC

Only as I have it coded. I am passing the body as a single plsql varchar2 variable.

If you passed a temporary clob and wrote it out 32k at a time, you could make it as large as you wanted. There is no limit (well, 4gig)

sending multiple emails in a single SP

nagaraju, April 04, 2002 - 5:20 pm UTC

If i have to send multiple emails,like typicallly.

i have a cursor that returns email addresses and other detials. i need to loop and email the other details to the email address

is it only the following way or anyother simple way

declare
l_mailhost VARCHAR2(255) := 'our mail server';
l_mail_conn utl_smtp.connection;
g_crlf char(2) default chr(13)||chr(10);
begin
l_mail_conn := utl_smtp.open_connection(l_mailhost, 25);
utl_smtp.helo(l_mail_conn, l_mailhost);
for rec in c_email_cur
loop
utl_smtp.mail(l_mail_conn, 'nagarajuk@hotmail.com');
utl_smtp.rcpt(l_mail_conn, rec.email_address);
utl_smtp.open_data(l_mail_conn );
utl_smtp.write_data( l_mail_conn, 'Date: ' || sysdate || g_crlf );
utl_smtp.write_data( l_mail_conn, 'Subject: ' || 'Testing utl_smtp' || g_crlf );
utl_smtp.write_data(l_mail_conn,'To: ' || rec.email_address || g_crlf);
utl_smtp.write_data(l_mail_conn, 'This is a Reminder for a Notification Received originally on: March 1, 2002.'|| g_crlf);
utl_smtp.write_data(l_mail_conn, g_crlf);
utl_smtp.write_data(l_mail_conn, 'The Access Removal form attached requires your immediate attention. '||rec.somevalue || g_crlf);
utl_smtp.write_data(l_mail_conn, g_crlf);
utl_smtp.write_data(l_mail_conn, 'Access Removal Request For:'|| g_crlf);
utl_smtp.write_data(l_mail_conn, g_crlf);
utl_smtp.close_data(l_mail_conn );
end loop;
utl_smtp.quit(l_mail_conn);
end;

any suggestions?

thanks

Tom Kyte
April 04, 2002 - 7:19 pm UTC

Yes, use modular code and factor out repeated processing

Write a send_mail routine (or just use the ones above).

then it becomes:

begin
for rec in ( select ... )
loop
send( .... );
end loop;
end;
/

Thats what procedures are all about.

Attaching a bfile

Johan Snyman, April 09, 2002 - 5:11 am UTC

Can you please indicate how the code need to be changed to e-mail a bfile as an attachment (I have to e-mail compressed files in an OS filesystem).

I am just starting to learn Java and don't even know where to start with above mentioned problem (although I expect at least the BLOBDataSource nested class to change or a similar class for bfile to be added).

By the way - which resources would you suggest for learning Java, coming from an Oracle background ?

Tom Kyte
April 09, 2002 - 7:56 am UTC

Should be as easy as changing p_attachment_type to BFILE and opening the BFILE in plsql before calling java -- the api for reading a bfile in java is the same as a blob.

You might consider:

</code> http://www.amazon.com/exec/obidos/ASIN/1861006020/ <code>

it has some nifty utilities in it. It is written for the PLSQL developer that wants to get their feet wet with some java.

Email from database

Randy Richardson, April 10, 2002 - 9:44 am UTC

Tom,

Is there a way to validate the TO list before sending? Or do you have to just send and let the bad email addresses fail? We are using MS exchange 2000 mail server and would like to do validation against the address book.

Thanks.



Tom Kyte
April 10, 2002 - 10:22 am UTC

Well, the email is coming from the database (on the server)

The address book is in exchange or on the client...


If you can ask MS how to access the address book via java, we can certainly do that. (hmm, isn't this how email viruses get started?)

I'm doubtful, all kinds of security issues with accessing the address book (you have to "trust" the oracle account) and I don't know if Java can access that or not. We could use C as well if they support that -- but the security issues abound.

java option in oracle

srividhya, April 15, 2002 - 2:58 am UTC

Hi Tom,

Thanks a lot for the mail.It is really great and working fine.We had installed on the development database(oracle 8.1.6) and had no problems with it. However, when we tried to deploy on our live database(oracle 8.1.6), we are facing a lot of installation problems. We realized that the java option has not been set when the database was setup(1.5 years ago).The database size is 25GB.How do we set the java option?We are not able to set the java option as an incremental update.How do we do that.
Thanks in advance.
Please reply...!!. We are just held up in deploying it.

Failure tracking from Oracle

rajiv, April 18, 2002 - 12:01 pm UTC

tom,

is it possible to track the failure of an email.

assume that i am sending email using utl_smtp with TO list has one person and CC list has 10 persons.
now email was sent to all the CC people but not to the TO list person.

in this case i need to send an email to an ADMIN saying email to that TO person is failed

is it possible?

Tom Kyte
April 18, 2002 - 12:24 pm UTC

the email will bounce tot he REPLY-TO address. set the reply-to to admin. I believe there is an "error-to" or something like that as well. you would have to look it up somewhere....

Failure tracking from Oracle

rajiv, April 22, 2002 - 11:35 am UTC

can you give me how do set the reply-to address to admin.
because when i tried in the following way mail is not sent to the admin. but the bounced mail come to the from addressee only.

l_fromaddr varchar2(50); -- assign the from address here
l_replyto varchar2(50);

PL/SQL to do email and appointment

Binh Ta, May 03, 2002 - 11:10 am UTC

Hi Tom,
Very helpful indeed. But I can you answer my follow-up question too please: How can one use PL/SQL to create Appointments in Exchange? I've searched practically the whole internet but found nothing. Would really appreciate if you can shedsome light. Many thanks. Binh Ta.

E-mail

Munz, May 24, 2002 - 9:48 pm UTC

Tom:

Do I understand that if I want to send an email but with a subject line and a message pulled out of the database I can do it with PL/SQL.

I only need to use jAVAMAIL API when I need t osend attachments.

THank you,


Tom Kyte
May 25, 2002 - 9:04 am UTC

You never *need* javamail, you could use utl_smtp 100%.

It is just much much easier with javamail to send attachments, it does the work for you.

UTL_SMTP is sufficient for sending text based email

email

Munz, May 31, 2002 - 10:30 am UTC

Tom:

If you do not want to use named parameters and not cc or bcc anyone in email how do you pass parameters.

I am getting an error when I do:

begin
mail_pkg.send(
'myname@att.com',
null,
mail_pkg.array('myname@att.com'),
mail_pkg.array(' '),
mail_pkg.array(' '),
'This is a subject',
'Hello Tom, this is the mail you need' );

dbms_output.put_line('Message sent to the user successfully');
end;
/

Can't you pass null values to an array.

Thanks,



Tom Kyte
May 31, 2002 - 10:40 am UTC

why don't you want to use named parameters? they are better then positional, you are not calling this from SQL so that is not an issue.

Otherwise, arrange the parameters to suit your needs (but wait, that'll break your other code unless it uses named parameters)

I would recommend you use a named parameter, it is more readable, less ambigous and if someone changes the order on you later -- you are PROTECTED.

You can do this:

begin
mail_pkg.send( 'sender email', 'from', mail_pkg.array('to'),
mail_pkg.array(), mail_pkg.array(),
'subj', 'body' );
end;
/

as well. You are not passing an empty array - you passed an array with some blank strings -- very different. Just pass empty arrays (like I have them defaulted to)



database link

frustrated mailer, June 10, 2002 - 6:03 pm UTC

TCPConnection class is not loaded in database I want to send mail out from, but the classes are loaded in another db behind the firewall that I can access through a db link.

I have tried creating a synonym for UTL_SMTP using the db link. Should this work?

I also tried writing a package that accepts the same inputs send mail does, but just calls send mail across the db link with the same arguments it was called with.

This doesn't work either. I get wrong number or type arguments.

Can you show how you would call UTL_SMTP across a db link from a db that doesn't have the java classes installed?



Tom Kyte
June 11, 2002 - 10:29 am UTC

utl_smtp uses a record. you are probably not defining your connection record using this remote utl_smtp package.


tkyte@TKYTE816> create or replace

Some details when using UTL_SMTP...

Sven Bleckwedel, June 19, 2002 - 1:36 pm UTC

Hi TOM,

Your explanation was very useful to help me to implement this resource in a database that i administer.  When using another character set (in my case, WE8ISO8859P1) some problems appeared, but i´ve found some tips that helped me to solve this problem, too:

<quote>
The original SMTP protocol communicates using 7-bit ASCII. But if the target SMTP server supports 8BITMIME extension, the user can convert the non-US7ASCII data to RAW and use the write_raw_data procedure to send data using 8-bit MIME 
encoding
...
Using the utl_smtp and utl_tcp packages requires that the JServer option is installed in the database.
Reference: Oracle8i Supplied PL/SQL Packages Reference, 65 UTL_SMTP
<quote>

- The code, before changes:

 61 writeData('Date: ' || l_date);
 62 writeData('From: ' || nvl(p_from, p_sender_email));
 63 writeData('Subject: ' || nvl(p_subject,'(nosubject)'));
 64
 65 writeData( l_to_list );
 66 writeData( l_cc_list );
 67
 68 utl_smtp.write_data(g_mail_conn, '' || g_crlf);
 69 utl_smtp.write_data(g_mail_conn, p_body );
 70 utl_smtp.close_data(g_mail_conn );
 71 utl_smtp.quit(g_mail_conn);

- After changes are made, at lines 65-67 and 72:

 61 writeData('Date: ' || l_date);
 62 writeData('From: ' || nvl(p_from, p_sender_email));
 63 writeData('Subject: ' || nvl(p_subject,'(no subject)'));
 64
 65 utl_smtp.write_data(g_mail_conn,'MIME-Version: 1.0' || g_crlf);
 66 utl_smtp.write_data(g_mail_conn,'Content-Type: text/plain; charset=iso-8859-1' || g_crlf)
 67 utl_smtp.write_data(g_mail_conn,'Content-Transfer-Encoding: 8bit' || g_crlf);
 68
 69 writeData( l_to_list );
 70 writeData( l_cc_list );
 71 
 72 utl_smtp.write_raw_data(g_mail_conn,utl_raw.cast_to_raw(g_crlf || p_body));
 73 utl_smtp.close_data(g_mail_conn );
 74 utl_smtp.quit(g_mail_conn);

- But, other problems appeared:

File system file as attachment

Vikas, June 27, 2002 - 1:50 pm UTC

Hi Tom,
This uses the file stored in the database for attachment. can you pl tell me how to do it for file system. Actually I want to use a browse button for attachments in which user will select file from client os(own system). I am using mod_plsql. Do i need to upload that file in the database and than execute your procedure. or there is any direct apporach. I am wondering how it can be done? Because mod_plsql does not support file system uploads( from client file system to server file system).

Tom Kyte
June 27, 2002 - 2:22 pm UTC

If you want to

a) send email from the server
b) with a file from the client

you'll have to upload the file to the server (mod_plsql will be great for that). Then, it'll be in a blob and the code will work "as is". After you email the document, delete the blob.

Tom Kyte
July 11, 2002 - 6:59 pm UTC

My name is Mark Piermarini and I work for Tom. He asked me to help you. I have a few questions:

1. Database version?
2. Operating system of the database host?
3. Did you load activation8i.zip before mail8i.zip?
4. Did you get any errors when loading either of the ZIP files? (if so then send those as well).
5. Are any of the classes marked invalid when you look at them with SQL Navigator?
6. What user is running the SQL to create the PL/SQL wrapper and java stored procedure? SYS or another user?
7. Have you tried loading the ZIP and SQL file as another user? (might not work depending upon you database version).

If I recall correctly, there was an issue with the "-g" option for loadjava but i'll have to get your DB version before verifying that as a potential problem.

p_subject => 'Use the attached Zip file',
p_body => 'to send email with attachments....',
p_smtp_host => 'smtpHOST',
p_attachment_data => l_bfile,
p_attachment_type => 'application/winzip',
p_attachment_file_name => 'mail8i.zip');

if ret_code = 1 then
dbms_output.put_line ('Successfully sent message...');
else
dbms_output.put_line ('Failed to send message...');
end if;
dbms_lob.fileclose( l_bfile ) ;
end;

I have tried on 9i and it is working fine!

Tom
do you have idea how big could be an attached file?
Could you give as a link or info where we can find info about MIME types?
Thanks

Error trying to run javamail.send function

Richard Smith, August 01, 2002 - 6:06 pm UTC

I successfully executed the pl/sql based mail functions in the article, loaded the JAXF and javamail apis and created the java stored procedure, granted permissions, and created the pl/sql wrapper function. Then when I execute an anonymous block using the same values for from, to, and smtp host as in the utl_smtp examples I get the following error:

javax.mail.NoSuchProviderException: No provider for Address type: rfc822
at javax.mail.Session.getTransport(Session.java:516)
at javax.mail.Transport.send0(Transport.java:155)
at javax.mail.Transport.send(Transport.java:81)
at mail.send(mail:71)

PL/SQL procedure successfully completed.

Tom Kyte

do a search for

javax.mail.NoSuchProviderException: No provider for Address type: rfc822

on www.google.com.

......
According to Sun's JavaMail FAQ:

Usually this is because JavaMail can't access the configuration files in mail.jar, possibly because of a security permission problem; see this item for more details. Also, make sure that you haven't extracted the mail.jar contents; you should include the unmodified mail.jar file in the server's CLASSPATH.
.................


It is a java thing, not a database thing here. You might be missing a permission

All Good ..But need to encrypt the attachments...!

Manoj Bajaj, August 08, 2002 - 3:26 am UTC

Tom, Life for programmer has never been easy. We started using the email utility..Now it sends attachments...many attachments tooo...but now one more secutiry reuirement..To encrypt the attachments and send ...imp. the user / receiver shoud be able to decrypt it ..how ?? hope u can show some path...

Tom Kyte

beyond the scope of asktom here. It'll be very specific to the email client.

sorry.

Sending multiple emails

A reader, August 27, 2002 - 11:53 am UTC

Excellent work Tom,
Here is my problem..
I am trying to run the procedure given by you in a cursor...
(we need to automate the email sending procedure...a job will run in the morning)...
Recipient, to, cc, bcc...all the info will come from a table:
SQLWKS> desc tab_email
Column Name Null? Type
------------------------------ -------- ----
RECIPIENT VARCHAR2(500)
CC VARCHAR2(500)
BCC VARCHAR2(500)
SUBJECT VARCHAR2(500)
MESSAGE VARCHAR2(900)

recipient, cc, bcc will be comm-delimited list of email addresses for example,
a record from the tab_email (Recipient) will be stored exactly like this in the database:
'this@hotmail.com','that@yahoo.com'



CREATE OR REPLACE procedure send_emails as

cursor c_cur is
select * from tab_email;

begin

for c_rec in c_cur loop


mail_pkg.send
( p_sender_email => '"automated mail"',
p_from => '"automated mail"',
p_to => mail_pkg.array(c_rec.RECIPIENT),
p_cc => mail_pkg.array(c_rec.cc),
p_bcc => mail_pkg.array(c_rec.bcc),
p_subject => c_rec.subject,
p_body => c_rec.message);


end loop;

end;


this compiles fine.....but when I run it....
I get

ERROR at line 1:
ORA-20002: 501 5.5.4 Invalid arguments
ORA-06512: at "SYS.UTL_SMTP", line 86
ORA-06512: at "SYS.UTL_SMTP", line 204
ORA-06512: at "MANAGER.MAIL_PKG", line 54
ORA-06512: at line 1

If I don't pass values through a cursor....the procedure works O.K.
Is there a Tom Classic way of getting this going....

I am using PL/SQL solution because we don't have attachment issues.
We are using Oracle 8i (8.1.7.1.1)

Thanks..Always


Tom Kyte
August 27, 2002 - 1:39 pm UTC

Well, my line 54:

49 begin
50 g_mail_conn := utl_smtp.open_connection(g_mailhost, 25);
51
52 utl_smtp.helo(g_mail_conn, g_mailhost);
53 utl_smtp.mail(g_mail_conn, p_sender_email);
54

Here is where it differs, instead of calling UTL_SMTP.RCPT once ? it uses are
address_email function to call it potentially many times, building the ?To:? and
?Cc:? list for us as well. It builds the BCC list but we won?t actually send
that (we don?t want the recipients to see that list!)

55 l_to_list := address_email( 'To: ', p_to );
56 l_cc_list := address_email( 'Cc: ', p_cc );
57 l_bcc_list := address_email( 'Bcc: ', p_bcc );

contains no code, so I don't know if it is a problem with your:

sender_email
p_to
p_cc
p_bcc


Suggest you code this:

CREATE OR REPLACE procedure send_emails as

cursor c_cur is
select * from tab_email;

begin

for c_rec in c_cur loop

begin
mail_pkg.send
( p_sender_email => '"automated mail"',
p_from => '"automated mail"',
p_to => mail_pkg.array(c_rec.RECIPIENT),
p_cc => mail_pkg.array(c_rec.cc),
p_bcc => mail_pkg.array(c_rec.bcc),
p_subject => c_rec.subject,
p_body => c_rec.message);
exception
when others then
raise_application_error( -20002,
'"' || c_rec.recipient || '" "' || c_rec.cc || '" "' || c_rec.bcc || '"' );
end;

end loop;

end;


run that and your error message will including the "bad" stuff that you can test with from the command line to see what you need to fix up.

Another issue...thanks for the first reply

A reader, August 27, 2002 - 4:25 pm UTC

Tom,


I actually came up with another solution...again from your site...
I created a function:
CREATE OR REPLACE FUNCTION MAIL_ARRAY (PSTRING VARCHAR2) RETURN MAIL_PKG.ARRAY AS

L_ARRAY MAIL_PKG.ARRAY := MAIL_PKG.ARRAY();
BEGIN
FOR X IN (SELECT A.COLUMN_VALUE
FROM THE (SELECT CAST(in_list(PSTRING) AS MYTABLETYPE_VARCHAR2)
FROM DUAL) A
)
LOOP
L_ARRAY .EXTEND;
L_ARRAY (L_ARRAY.COUNT) := X.COLUMN_VALUE;
END LOOP;

RETURN L_ARRAY;

END MAIL_ARRAY;

/


Then I ran the procedure like this:
CREATE OR REPLACE PROCEDURE SEND_EMAILS AS

CURSOR C_CUR IS
select * from tab_email;

BEGIN

FOR C_REC IN C_CUR LOOP

MAIL_PKG.SEND
( P_SENDER_EMAIL => '"Automated Mail Message"',
P_FROM => '"Automated Mail Message"',
P_TO => MAIL_ARRAY(C_REC.RECIPIENT),
P_CC => MAIL_ARRAY(C_REC.CC),
P_BCC => MAIL_ARRAY(C_REC.BCC),
P_SUBJECT => C_REC.SUBJECT,
P_BODY => C_REC.MESSAGE);


END LOOP;

END;


This work's perfect...and there is always a "BUT" :)
My table structure that will feed the records to the cursor
will be like this:

SQLWKS> desc email
Column Name Null? Type
------------------------------ -------- ----
EMAILID NOT NULL NUMBER
RECIPIENT NOT NULL VARCHAR2(500)
CC VARCHAR2(500)
BCC VARCHAR2(500)
SUBJECT NOT NULL VARCHAR2(255)
SUBMITDT NOT NULL DATE
SENTYN NOT NULL VARCHAR2(1)
SENTDT DATE

SQLWKS> desc email_message
Column Name Null? Type
------------------------------ -------- ----
MESSAGEID NOT NULL NUMBER
EMAILID NOT NULL NUMBER
MESSAGE NOT NULL VARCHAR2(900)


so,
"CURSOR C_CUR IS
select * from tab_email;"

will change to
"
CURSOR C_CUR IS
SELECT E.EMAILID, M.MESSAGEID, E.RECIPIENT, CC,BCC, SUBJECT, SENTYN, SENTDT
FROM EMAIL E, EMAIL_MESSAGE M
WHERE E.EMAILID = M.EMAILID (+)
ORDER BY EMAILID, MESSAGEID;
"


email_message.emailid is an FK to EMAIL.emailid.
so that, an emailid can have multiple messages..so there won't be any constraint on the length of the message...keep concatenating...
fine...
"BUT"
Now we have declared p_body in mail_pkg.send as LONG...so that
is 32000 approx.
Maximum length of a message (all the messageid's combined for an emailid) that I have seen in our data is 16452.
(Concatenated message for an emailid will be passing as mail_pkg.send(p_body) parameter)

So, at some point there is a chance this code might break..
Is there a better way to do this...

Thanks Always...







Tom Kyte
August 27, 2002 - 4:39 pm UTC

rewrite my stuff to use CLOBS instead of LONGS and store the message in a clob instead.

If a plain text email exceeds 32k -- man, that must be one heck of an email.

CLOBS hmmmm

A reader, August 27, 2002 - 5:05 pm UTC

Tom,

:)))))))))))))))))
Well, it did go to 16452.....
We are sending contractors emails about their projects..something something...
it's not somebody writing their lifestory :))))))
Anyway,
I will change LONG to CLOB....

Thanks a zillion to the power infinity for the Superfly Quick replies...

You are the Best...



CLOB fails on utl_smtp.write_data :(

A reader, August 27, 2002 - 5:35 pm UTC

I changed procedure send to:

procedure send( p_sender_email in varchar2,
p_from in varchar2 default NULL,
p_to in array default array(),
p_cc in array default array(),
p_bcc in array default array(),
p_subject in varchar2 default NULL,
p_body in clob default NULL )

so, p_body is a CLOB now..
"BUT" it fails to compile..because data is varchar2

utl_smtp:
PROCEDURE write_data(c IN OUT NOCOPY connection,
data IN VARCHAR2);

Now, How was it working with LONG anyway?

Here is the line and the error:

70> utl_smtp.write_data(g_mail_conn, p_body );

"70/5 PLS-00306: wrong number or types of arguments in call to 'WRITE_DATA' "

Any ideas....

Thanks...



Tom Kyte
August 27, 2002 - 9:22 pm UTC

Well you have to rewrite the code ALL OF THE WAY down to the utl_smtp.write_data call and write the CLOB out 32k at a time!

getting error

A reader, August 28, 2002 - 9:35 pm UTC

Nope, you must have missed a grant or something like that.

Put some debug in there and snoop around - i've used this on pretty much every release of Oracle since 815

followup to my response above

A reader, August 28, 2002 - 9:40 pm UTC

Just wanted to clarify...
I am using utl_smtp...just the way you said to send email..
no java..then
Why this Java error..

Tom Kyte
August 29, 2002 - 5:22 pm UTC

UTL_SMTP is written in java.

Time for some debug. Find out where it is happening.

found the error

A reader, August 30, 2002 - 8:25 am UTC

if you pass null to the p_body..that's when ora-29532 java error occurs..
NVL took care of that issue..

Thanks Tom.....

excellent piece of art!

Arielito Lopez, September 10, 2002 - 12:10 pm UTC

thanks for this information...it helps a lot!

Mukesh Thakkar, September 24, 2002 - 2:09 pm UTC

Hi
I am running Oracle 8.1.7 RDBMS on windows NT/2000. I can get utl_smtp to work fine sending emails. However when I use the Javamail API as shown I get the following errors

Well, thats a java exception -- you must have not sent the right inputs (like a recipient - a to list) down to the routine.

It worked fantastic on Oracle 9i on Sun Solaris !!! Thanks a lot

I followed all the steps, except deviated while running loadjava with user as system and I got errors, then went back to SYS and it ran through.

It is very very useful, specially in the project I am working with i.e. Digital Asset Management. A lot of files and reports are required to be mailed as attachment for reviews, reports, etc.

Thanks a lot !!!

Tom:

If I want to CC several people do I create a variable that holds all emails included in ' ' and separated by a comma and use it in

v_email1:= 'mike@yahoo.com';
v_email2:= 'John@aol.com';
v_email3:= 'mary@msn.com';
v_cc_list := v_email1||','||v_email2||','||v_email3;

p_cc => mail_pkg.array( v_cc_list ),

2. Would the email package work if the p_to has a null variable while the p_cc has a list of emails or you have to have to. The reason I ask this is that sometimes you send emails based on user profile flag. The to person may have it off while the one on CC is on.

Thank you


Tom Kyte
October 31, 2002 - 4:33 pm UTC

not as I have the code written. you would do it just like the example does for the p_to parameter below:

tkyte@TKYTE816> begin
2 mail_pkg.send
3 ( p_sender_email => 'tkyte@us.oracle.com',
4 p_from => 'Oracle Database Account <tkyte@us.oracle.com>',
5 p_to => mail_pkg.array( 'tkyte@us.oracle.com',
'thomas.kyte@oracle.com' ),
6 p_cc => mail_pkg.array( 'tkyte@oracle.com' ),
7 p_bcc => mail_pkg.array( 'utility@aria.us.oracle.com' ),
8 p_subject => 'This is a subject',
9 p_body => 'Hello Tom, this is the mail you need' );
10 end;
11 /

an array, not a comma delimited string. YOu would have to parse the string into an array somewhere.

email

mo, October 31, 2002 - 5:50 pm UTC

Tom:

1. What do you use to parse a string into an array. Do you have any reference for examples?

2. How about if I declared a variables of an array type

type emailArray is table of varchar2(8);
email emailArray:=emailArray(null,null,null,null,null;

Then I select first email into email(1) and second into
email(2) and so on.

Would just use this then:

p_to => mail_pkg.array(email)

would this work.


Tom Kyte
October 31, 2002 - 9:27 pm UTC

1) search for

str2table

for an example (on this site)

2) or just

...
l_emails mail_pkg.array := mail_pkg.array(); /* gotta use the SAME type, don't
invent your own!!!! */
....
begin
....
l_emails.extend(4);
l_emails(1) := ...
l_emaisl(2) := ....
......



and then just


p_to => L_emails,



..and under Oracle9i ?

Mario, December 02, 2002 - 10:35 am UTC

From your reply:

" loadjava -u sys/manager -o -r -v -f -noverify -synonym -g public mail8i.zip
loadjava -u sys/manager -o -r -v -f -noverify -synonym -g public "

1) But under Oracle9i you can log in as "sys" only with the special "as sysdba". How can I workaround it?

Apparently the "Java Developer’s Guide", for Oracle9iR2 obviously, doesn't say anything about this issue.

2) Is there a better way under Oracle9i to send an email with an attachment?

Thank you very much Tom

Can you still use utl_smtp to send emails out out of the database to users outside of a firewall, if you have a database server that is not on the internet. Server has classified info and is only accessed through app server.

Thanks,



Tom Kyte
December 04, 2002 - 8:29 am UTC

only if you can send an email out from the command line using "mail" from the server.

Do you have an SMTP relay to the outside? if not, no go. Nothing to do with utl_smtp here, more with the firewall policies and how it is setup. If the database server HOST can send emails to the outside, then utl_smtp certainly can. If not, then no.

excellent

Hi Tom,

Your procedure of sending mails from D2K was execellent.i got it within notime and is working fine till now.
here my reqiurements,realted to ur application.sending is ok.my question is ,when i recieve the mail,it will go to my exchange server.
what i want is,recieve the mails in D2k form itself.is there any possibility that i can store the incoming mails in D2K form instead of going in exchange server.plz,help me out in this matter.
waitng for ur answer.
thanks
Mohd.salim.

Tom Kyte

forms is just an application development tool. It doesn't "store anything"

You must mean the database, the java apis above are capable of "reading" mail as well as sending it. You just need read up on the java mail api and then you'll have to build a set of tables and such to store the retrieved mail in.

try loading it not into sys, but your own schema and see what happens. that way you can work with it.

(not sure, but maybe i have the loadjava's backwards? try activation first)

Benchmarking

Scott, January 23, 2003 - 12:47 am UTC

G'day Tom

For those who are interested, I did some benchmarking (on our development box) to compare the two emailing methods.

1 - SMTP
2 - Javamail

The SMTP benchmark used on session, and mailed within that session. This was much better performance than using one session per email.

Each count represents a batch of 5 emails, to split the load, in case the server activity varied.
Sum and avg is in hsecs.

No attachments...(ie - 200 emails - 100 each)

SUM_1 SUM_2 AVG_1 AVG_2 COUNT_1 COUNT_2
--------- ---------- ---------- ---------- ---------- ----------
3423 2040 85.58 51 20 20

44kb attachment included.

SUM_1 SUM_2 AVG_1 AVG_2 COUNT_1 COUNT_2
--------- ---------- ---------- ---------- ---------- ----------
202041 74569 3741.5 1380.91 27 27

So when using attachments, Javamail had even better performance compared to UTL_SMTP.

Here are some other runs with various conditions varied. Each number represents a run of 100/50 emails, so server usage may have affected some of these results.
Javamail outperformed UTL_SMTP in all but runs 7 and 8.
The first two runs using UTL_SMTP (1 and 3) are opening one session per email - hence the long run-time.
-- (100 emails each)
1 #1: 10752 hsecs (10.75 seconds)
2 #2: 6100 hsecs
3 #1: 10329 hsecs
4 #2: 5247 hsecs
5 #1: 6537 hsecs
6 #2: 5287 hsecs
7 #1: 4789 hsecs
8 #2: 5047 hsecs
9 #1: 6060 hsecs
10 #2: 2910 hsecs
11 #1: 7344 hsecs
12 #2: 4214 hsecs
-- attachments (50 emails each)
13 #1: 46616 hsecs
14 #2: 19054 hsecs
15 #1: 40845 hsecs
16 #2: 17496 hsecs

Thanks for your contributions, Tom.


Great - Spot on

Following your suggestion, we have successfully loadjava for the zip files and implemented it.

You were right in saying activation8i.zip needs to be loaded first.

Thanks again.

util_smtp package

naivedya, February 20, 2003 - 2:34 am UTC

It is very good, for sending mails. But at the same time I wish to attach my attachments (txt, doc, etc. or database fields). How do I do this with PL/SQL (no Java) ??

Rgds


Tom Kyte
February 20, 2003 - 7:29 am UTC

with tons and tons of code.

Lets see, you would have to write a mime encoder.
You would have to write a base64 encoder.
You would have to write tons and tons and tons of code.

Now, in 8i, utl_smtp is in java so you are already using java -- in for a penny -- in for a pound as they say. you are using java already so just add a "little bit more" and you won't have to write scads of code.

Characters not in us7ascii

Salaam Yitbarek, March 26, 2003 - 3:36 pm UTC

So we are now successfully sending email using UTL_SMTP all except for one thing -- accented characters in the subject field.

From the Solaris command line, I can successfully send mail with accented characters. However, using UTL_SMTP, this does not work.

I don't mind it not working in the body, since we're sending html (&agrave instead of à), but the subject line is a problem.

Our database character set is we8iso8859pi.

Tom Kyte
March 26, 2003 - 6:35 pm UTC

...
Note that the original SMTP protocol communicates using 7-bit ASCII. Using UTL_SMTP, all text data (in other words, those in VARCHAR2) will be converted to US7ASCII before it is sent over the wire to the server.

You can use javamail instead if you like.

UTL_SMTP and sending mail

A K Prasanna, March 28, 2003 - 12:43 am UTC

I was pretty frustrated that "Expert One on One Oracle"
is not available in the library to refer to this topic but I don't think I need any book now.Thank you very much.

email table

mo, April 24, 2003 - 2:54 pm UTC

Tom:

1. How do you send results of the emp table (or any sql query) using the above email package.

Basically the result of this SQL command
select * from emp1;

Thank you,


Tom Kyte
April 24, 2003 - 3:34 pm UTC

same way you get it onto an html page.

run it, fetch it, send it. put it in a big string, email it.

email table

mo, April 24, 2003 - 3:54 pm UTC

Tom:

I did this:

v_data long default null;

FOR x in (select * from emp)
LOOP
v_data:=v_data||x.empno||' '||x.ename||' '||x.job||' '
||x.mgr||chr(10);
END LOOP;

then in the email package
p_body => v_data

However the data is not lined up as it does in SQL*PLUS.

Is this how you do it and can i get it lined up?

Thank you,


Tom Kyte
April 24, 2003 - 4:22 pm UTC

well, I don't email myself "select * from table" output.

I email things like "hey, click on this link and you'll get a really pretty report on the web".

But anyway, think fixed width

email

mo, April 24, 2003 - 6:05 pm UTC

Tom:

1. When you schedule the job as
dbms_job.submit(l_job,'SEND_EMAIL(JOB);');
DOes that send the email as soon as you hit commit?

I did it but it did not send an email. Is it because
job_queue_processes = 0.

2. Do you delete records in tables email_parameters and job table after you commit or every period.

Thank you

Tom Kyte
April 24, 2003 - 6:24 pm UTC

1) if you do not have job queues set up to run jobs, it'll not run. set up the job_queue_processes and it'll send shortly after you commit.


2) you can do whatever suits your needs, what I do isn't relevant here. I keep them as an audit and purge every now and again when I feel like it with truncate.

Large to Lists

Randall, April 25, 2003 - 3:09 pm UTC

Tom, Thanks for all the help. We have utl_smtp in 8.1.7 working great now for some time. We use it to notify employees when changes are scheduled on systems that would affect them.

We did get an error today,
"ORA-20001: 452 Too many recipients"

The email that it was tring to send had 512 names on it with the TO list having a length of 14215. The email body is only about 6k and will never have a body bigger that 10k. Even thought this large TO list is not normal, it can happen. So I guess I will write some logic to break up the TO list and send multi SMTP emails.

Can you tell me what the limits are for UTL_SMTP for:
1. number of recipients
2. total size of TO: list (can you have multi TO: headers?)
3. max size of subject line
4. Does the 32k limit include body, TO list, and subject or just the size of the body.

Thanks for all the help and have a good weekend.



Tom Kyte
April 25, 2003 - 3:52 pm UTC

this is NOT a utl_smtp limit.

this IS a smtp limit imposed by your SMTP server


snipped from RFC 2821 which talks about this



4.5.3.1 Size limits and minimums
[snip]
recipients buffer
The minimum total number of recipients that must be buffered is
100 recipients. Rejection of messages (for excessive recipients)
with fewer than 100 RCPT commands is a violation of this
specification. The general principle that relaying SMTP servers
MUST NOT, and delivery SMTP servers SHOULD NOT, perform validation
tests on message headers suggests that rejecting a message based
on the total number of recipients shown in header fields is to be
discouraged. A server which imposes a limit on the number of
recipients MUST behave in an orderly fashion, such as to reject
additional addresses over its limit rather than silently
discarding addresses previously accepted. A client that needs to
deliver a message containing over 100 RCPT commands SHOULD be
prepared to transmit in 100-recipient "chunks" if the server
declines to accept more than 100 recipients in a single message.

Errors due to exceeding these limits may be reported by using the
reply codes. Some examples of reply codes are:

500 Line too long.
or
501 Path too long
or
452 Too many recipients (see below)
or
552 Too much mail data.

RFC 821 [30] incorrectly listed the error where an SMTP server
exhausts its implementation limit on the number of RCPT commands
("too many recipients") as having reply code 552. The correct reply
code for this condition is 452. Clients SHOULD treat a 552 code in
this case as a temporary, rather than permanent, failure so the logic
below works.

When a conforming SMTP server encounters this condition, it has at
least 100 successful RCPT commands in its recipients buffer. If the
server is able to accept the message, then at least these 100
addresses will be removed from the SMTP client's queue. When the
client attempts retransmission of those addresses which received 452
responses, at least 100 of these will be able to fit in the SMTP
server's recipients buffer. Each retransmission attempt which is
able to deliver anything will be able to dispose of at least 100 of
these recipients.

If an SMTP server has an implementation limit on the number of RCPT
commands and this limit is exhausted, it MUST use a response code of
452 (but the client SHOULD also be prepared for a 552, as noted
above). If the server has a configured site-policy limitation on the
number of RCPT commands, it MAY instead use a 5XX response code.
This would be most appropriate if the policy limitation was intended
to apply if the total recipient count for a particular message body
were enforced even if that message body was sent in multiple mail
transactions.

email

mo, April 25, 2003 - 3:50 pm UTC

Tom:

1. The email package seems to mandate a p_from email address. What about if the email message is an a system alert and it is not really from anyone. What do you do in this case? Do you put a dummy email address?

2. IF you have multiple send email triggers do you always use the same email_parameters table. Would there ever be a conflict in job id if one for example schedules the job two days later?

Thank you,



Tom Kyte
April 25, 2003 - 3:55 pm UTC

1) put in postmaster@host or something meaningful. mail cannot be sent without a from

2) one table, dbms_job generates a unique id using a sequence.

email with two emails addresses

mo, May 07, 2003 - 1:02 pm UTC

Tom:

1. Do you know why the email package fails when I add two variables in the p_to list?

2. It seems also if I put a variable for the cc_list it does not work if that vairable is null. I had to create an if statement to check if v_cc_email is null and include if it is not and not include if it is. Does this sound correct?

mail_pkg.send(
p_sender_email=>l_rec.sender_email,
p_from=>null,
p_to=>mail_pkg.array(l_rec.pvt_email,l_req.request_email),
p_cc=>mail_pkg.array(),
p_bcc=>mail_pkg.array('xxx@yahoo.com'),
p_subject => 'Request# '||l_rec.request_id||' - Shipment has been Completed',
p_body => l_rec.email_data);

Tom Kyte
May 08, 2003 - 9:01 am UTC

probably has nothing to do with "two"

probably has everything to do with your email address not being well formed in one of those two variables...

without an isolated, standalone, complete, runnable by my test case -- well, i won't be able to say.



email

mo, May 08, 2003 - 10:47 am UTC

Tom:

1. The variables are defined for two valid email addresses. You can set any two variables and try to pass them into the p_to list and it will fail. I created an array variable instead. The problem with array vairable "l_emails" is that you have to extend it exactly to the number of emails you are sending. When I did l_emails.extend(2) and my second email in the email_parameters table was null the email package failed. I had to pass i and figure out what i is.

Tom Kyte
May 08, 2003 - 6:15 pm UTC

show us the test case -- eh?


thats all I ask, self contained, reproducible, SMALL <<<=== really important.

your solution described fits NOT AT ALL with the problem presented:

mail_pkg.send(
p_sender_email=>l_rec.sender_email,
p_from=>null,
p_to=>mail_pkg.array(l_rec.pvt_email,l_req.request_email),
p_cc=>mail_pkg.array(),
p_bcc=>mail_pkg.array('xxx@yahoo.com'),
p_subject => 'Request# '||l_rec.request_id||' - Shipment has been Completed',
p_body => l_rec.email_data);



there is nothing to .extend there -- you are creating a temporary array. what you describe as your fix could have nothing to do with the example provided.

Send email does not work constantly

A Reader, May 09, 2003 - 3:29 pm UTC

Hi Tom,
I have system trigger that uses the send mail procedure to send email to me whenever there is a defined server error. The trigger sometimes works fine, I mean I receive emails when the errors occur. Sometimes it does not work (I don’t receive any emails where the errors occur). I know that by checking the trace files because there will be a trace file generated when the defined error appears. I want receive all of the emails when errors occur. My question: Where should I start with the debugging, the procedure or the trigger? Or the ora_is_servererror sometime does not response to the errors? My tests worked fine. The sendmail procedure was copied and modified from the beginning of this thread.
Thank you for your help.

CREATE OR REPLACE TRIGGER systrig_servererror
after servererror on database
begin
IF (ora_is_servererror(60) or ora_is_servererror(4020)) THEN

It is exactly what I said above then

tell me, is 'null' a valid email? no, it is not. Hence, you get the SMTP error (not an oracle error) of 501 saying "hey, that is not a valid well formed email address"



email

mo, May 09, 2003 - 10:41 pm UTC

Tom:

1. How would you get around it if one of the cc emails is null. Do you always check how many emails are not null and then do extend(i) rather than a fixed count?

2. The email package works if one of the emails is not valid at all? e.g, if i type 123@yahoo.com it will still work, even though it is not valid email?

Tom Kyte
May 10, 2003 - 7:33 am UTC

i would make darn sure there were no null emails in the array

obviously, since you own the code, you can modify the lowest level routine to just ignore nulls.


123@yahoo.com is perfectly "valid". It might not exists, but it conforms to the rules for email address format.

lose the when others, fix the third bug that is hiding in there once you know where and what it is!

Bulk email and sessions

Bastiaan, May 13, 2003 - 8:56 am UTC

Hi Tom,

We are using a similar procedure to send mail from our (PL/SQL web-) applications. From one of these applications we send personalised mail to people on a mailing list. We have a job scheduled to handle this. Now we have reached a point where our mailing list contains about 1500 mail-adresses, and the procedure that is scheduled in the job starts to fail. After investigating it turned out that the procedure failed every time it reached the 493rd person on the list. At that time there were 7 other sessions active (checked in v$sessions). Turns out that 493 + 7 is the maximum number of sessions we specified in the init.ora. Does every utl_smtp connection to a mailserver cause a (hidden) session to be started? Or is this just a coincidence?


Tom Kyte
May 13, 2003 - 9:08 am UTC

believe it is a coincidence. I send hundreds/thousands of emails daily using this technique.


do you have an error message.

hello tom,

I took this from your 1st sample above:

l_mail_conn utl_smtp.connection;

p_sender VARCHAR2(50) := 'me@somewhere.net';
p_recipient VARCHAR2(50) := 'me@somewhere.net';
p_message VARCHAR2(20) := 'message content';

BEGIN
l_mail_conn := utl_smtp.open_connection(l_mailhost, 25);
utl_smtp.helo(l_mail_conn, l_mailhost);
utl_smtp.mail(l_mail_conn, p_sender);
utl_smtp.rcpt(l_mail_conn, p_recipient);
utl_smtp.open_data(l_mail_conn );
utl_smtp.write_data(l_mail_conn, p_message);
utl_smtp.close_data(l_mail_conn );
utl_smtp.quit(l_mail_conn);
end;

but got only EMPTY messages. can you give some advice?

we are just talking "straight to smtp" here. You can do this with telnet - so the issue is NOT in the database.



Bulk email and sessions part II

Bastiaan, May 14, 2003 - 4:02 am UTC

Hi Tom,

Thank you for looking into my problem. The error messages I get back from the procedure are:

ORA-29278: SMTP transient error: 421 Service not available
ORA-00018: maximum number of sessions exceeded

I don't understand this because there is only 1 job, that runs the procedure. The procedure just takes a cursor loop through a table, and sends an email for every record...

My idea is that it's maybe the mail-server that doesn't accept any more connections (because of the 421 SMTP error), but within the procedure the smtp connection is closed, and at any given moment there should be only one connection from the database to the mailserver...

I haven't seen this myself -- but then, I use one connection call period in my procedures.

that means, just as it did before, that your host you are using is not running smtp services. tnpl.co.in is not running smtp on port 25.

ask your SA's where there is an smtp server in your network that does relaying.

Tom Kyte
July 07, 2003 - 8:44 am UTC

you are going to need to talk to your system admins here, this is not an Oracle error, it is purely an SMTP configuration issue at this point.

it is probably that you are not allowed to relay mail to @there.com

Flemming, July 16, 2003 - 6:48 am UTC

Hi Tom
I have a problem with the time-stamp of the email. In my code I have this statement:
utl_smtp.write_data(v_smtp_connection, 'DATE: '|| to_char(sysdate,'DD-MON-YYYY HH24:MI') || utl_tcp.CRLF);
I have verified that the time is correct in the code, but on the email the label for Sent shows a time that is 2 hours later. Any ideas ?
/Flemming

Tom Kyte
July 16, 2003 - 9:35 am UTC

timezones perhaps -- if it is correct to the 'minute', i would guess a time zone change is taking place either along the way or by the email client itself.

Ackownledgement Email...

vinodhps, July 20, 2003 - 7:19 am UTC

Hi Toms,
Now its working fine, and your Book and your website are so useful and your new book was good.. i read all the 3 chapters.. waiting to get one copy for me .. so when it is going to come in market.. (India)..

well i got recuirement, that after we send mail, is it possible to know that whether they have opened the mail , something like Ackownledgement - mail.when the opened.....

Is it possible Tom , If so how can we do that tom.

Thankyou


Tom Kyte
July 20, 2003 - 9:15 am UTC

that is a protocol private to email -- the CLIENT recieving it must be willing to send it (i for example, have that disabled -- i do not send ack's back)

then, you would need a client to read it.

In short - yes, you could -- but it would be fairly involved and outside of "an example" (meaning I'm not going to build it)

You would need to

a) find out what the protocol for acknowledgement is (something in the header undoubtably)

b) send that

c) figure out how you want to read the email (could be a java stored procedure in the database if you wanted)

acknowledgemen Mail

vinodhps, July 21, 2003 - 1:52 pm UTC

Hi Toms ....
for you responce ..
i searched in google.. i could not able to find any document which will help me..out ..

i will try myself..can you give some useful links or site where i can find anything about acknowledgemen mail ...tom

all i want is just to know wether they read the mail or not.

a) "(something in the header undoubtably)"

Can you explain this tom.

Thank you for your time



Tom Kyte
July 21, 2003 - 3:34 pm UTC

to tell whether they read a mail, the CLIENT must participate (meaning there is NO WAY you can rely on this even a little -- I for example disallow 100% the use of this feature on my client, it is NONE of your business when or if I've read your mail).

there must be some header that does this, me, being a database guy, not an email guy -- doesn't know the header in general.

try searching for

"return receipt" "header"

on google

Sending e-mail to groups of users at once

Daryl Green, July 30, 2003 - 2:23 pm UTC

Tom,

How can you use these methods to send e-mails to a group of users (at once) instead of addressing them each individually. I have security set up on my NT 8.1.6.3 database with profiles and would like to automatically send an email to all users whose password will expire in 10 or less days on a daily basis until the password has been successfully changed. Also, i have a web form (using Webdb) to allow user to change their passwords. I want to send an individual e-mail to them. How can this be done!

Thanks for all of you help!!!

Tom Kyte
July 30, 2003 - 2:46 pm UTC

you have to make an RCPT call once for each user is all.

Very nice

Sikandar Hayat, July 31, 2003 - 6:45 am UTC

Hi TOM,
I tried this 8i but it was not working there may be due to my poor knowledge of Java. Now in Oracle9i Rel2 I have tried and it is working.

Thanks for such a cool stuff.

How to send email to local users?

Sikandar Hayat, August 08, 2003 - 3:33 am UTC

create or replace PROCEDURE send_mail (p_sender IN VARCHAR2,
p_recipient IN VARCHAR2,
p_message IN VARCHAR2)
as
l_mailhost VARCHAR2(255) := 'smtpgw.cdc.gov';
l_mail_conn utl_smtp.connection;
BEGIN
l_mail_conn := utl_smtp.open_connection(l_mailhost, 25);
utl_smtp.helo(l_mail_conn, l_mailhost);
utl_smtp.mail(l_mail_conn, p_sender);
utl_smtp.rcpt(l_mail_conn, p_recipient);
utl_smtp.open_data(l_mail_conn );
utl_smtp.write_data(l_mail_conn, p_message);
utl_smtp.close_data(l_mail_conn );
utl_smtp.quit(l_mail_conn);
end;

begin
send_mail( 'bcv5@cdc.gov',
'bcv5@cdc.gov',
'Hello Tom' );
end;
If i run the procedure all i am getting is the from email id.

Awaiting your response



Tom Kyte
September 04, 2003 - 8:36 am UTC

in your email client, use the option to view the original unformatted email. Perhaps your client is hiding it from you. (this works -- this is just standard smtp stuff -- nothing simplier -- but I can imagine the email client you are using it mucking it up somehow. Lets see the "real" email)

Sending fax

A reader, September 23, 2003 - 8:59 am UTC

Is there anything 8i , 9i or 10G which would enable faxing from the database, just like emailing from the database, illustrated in this example ?

Thanks

Tom Kyte
September 23, 2003 - 11:04 am UTC

drop a java stored procedure in there -- there must be one out there that can interface with some fax software.

(oracle collaboration suite does this as well)

For time zones

Jon, September 25, 2003 - 11:15 am UTC

Thanks Tom, this works great for us.

We were concerned at first because our time was coming out wrong. Then we realized that we needed to append ' -0400' to the date so that it would show the time for the correct time zone (in our case, EST). Just thought other people may have ran into this problem...

Getting error when using JavaMail

Hi Tom,

I am running Oracle 8.1.7 on Windows 2000. I can get UTL_SMTP to send emails fine. However when I use the Javamail API as shown, I get the following errors:

Tom,

Been using this for awhile, and keep coming back to this link to find this procedure when it is needed in different places (since I don't keep it in my shirt pocket).

The package spec and package body for the send procedure are out of sync now though. default NULLS that are present in the body are missing from the spec on two or three of the attributes.

Tom Kyte
October 13, 2003 - 11:58 am UTC

they've always been like that :)

it just wasn't a problem until you upgraded to 9i! I had a bug that was OK in 8i, not in 9i. Just remove the defaults.

Sending Email Raw data

Vikas Sharma, October 22, 2003 - 3:15 pm UTC

Hi Tom,

I am sorry if i am posting this review at a wrong place.

I am trying to send mail using utl_smtp. I am not using the javamail api. I have writtena code using utl_smtp and setting up the MIME headers to send the text, html and any text files succesfully.

But i am facing problem in sending the birary file. I have set the mimie headers, i getting my file data send to mail server also but when i try to download the file it download with junk raw data.

To send the binary attachments i am doing the following things.
1. setting the mime headers to

--abs2sc3d74F7A1CD

Content-Type: application/octet
Content-Disposition: attachment; filename="mail.doc"
Content-Description: test-part-2
Content-Transfer-Encoding:base64

2. After setting the header i read the content of my file "mail.doc" and load the content to a blob using dbms_lob.loadfromfile. so now i have the content of the file into a blob. now i am using the following peice of code to write the blob data on SMTP

======================
l_offset := 1;
l_ammount := 57;
while l_offset < dbms_lob.getlength(l_blob) loop
utl_smtp.write_raw_data(l_connection,
(utl_encode.base64_encode(utl_raw.cast_to_raw(dbms_lob.substr(l_blob,l_ammount,l_offset)))));
l_offset := l_offset + l_ammount ;
l_ammount := least(57,dbms_lob.getlength(l_blob) - l_ammount);
end loop;
utl_smtp.write_data(l_connection,end_boundary); -- writing end boundary

=================================================

I am not sure is this the correct way of doing it. I have the data into a BLOB Do i need to cast in raw before i use utl_smtp.write_raw_data.?

If i cast to raw it using
(utl_smtp.write_raw_data(l_connection,
(utl_encode.base64_encode(utl_raw.cast_to_raw(dbms_lob.substr(l_blob,l_ammount,l_offset)))));

then the result of the content of files are like
===============================
Content-Transfer-Encoding:base64

RDBDRjExRTBBMUIxMUFFMTAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAw
M0UwMDAzMDBGRUZGMDkwMDA2MDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAxMDAwMDAw
MjEwMDAwMDAwMDAwMDAwMDAwMTAwMDAwMjMwMDAwMDAwMTAwMDAwMEZFRkZGRkZGMDAwMDAwMDAyMDAwMDAwMEZG

=================

If i dont use the use utl_raw.cast_to_raw ie using
utl_smtp.write_raw_data(l_connection,
(utl_encode.base64_encode(dbms_lob.substr(l_blob,l_ammount,l_offset))));

then the result are as follows

===============
Content-Transfer-Encoding:base64

0M8R4KGxGuEAAAAAAAAAAAAAAAAAAAAAPgADAP7/CQAGAAAAAAAAAAAAAAABAAAA
IQAAAAAAAAAAEAAAIwAAAAEAAAD+////AAAAACAAAAD/////////////////////////////////
////////////////////////////////////////////////////////////////////////////
////////////////////////////////////////////////////////////////////////////
=================

Pl suggest what i am doing wrong. i think somting is wrong when i am doing conversion of blob to raw.

Regards,

Vikas Sharma

Tom Kyte
October 22, 2003 - 6:23 pm UTC

sorry -- i don't know myself how to mime encode an entire email. I took the easy way out and borrowed the code from sun.

I would suggest the same to you! Its a nightmare trying to encode that junk.

i posted the error earlier also see above.
So i thought i will go for mime approach. And try with that.

Can you pl suggest me why i am encounter the above error my database is 8i(8.1.7). I loaded the mailapi version javamail 1.3 and frame work jaf-1.0.2 on sys account using your guide lines.

Btw pl tell me how can i use the blob data with "utl_smtp.write_raw_data" i am doing as following :

utl_smtp.write_raw_data(l_connection,
(utl_encode.base64_encode(utl_raw.cast_to_raw(dbms_lob.substr(l_blob,l_ammount,l_offset)))));

Is this correct?

i'll have a java dude take a look see and if he has any advice, will follow up.

base64 encoding -- as I remember it takes 3 bytes to store 2 or something like that. probably a boundary value condition, not sure that you can just "substr" like that and encode chunks. (this is why this becomes "hard". you have learn all about b64 encoding, something I haven't looked at in years myself)

and he says (the java guy)

Can you ask them to send a description of their table named "mailattachments". I wonder why they are setting the "filename" column to the actual data.

Also, it's looking for a data handler for "multipart/mixed" but I wonder why they are trying to attach that type to a mail message.

Even though he said he followed your instructions, I'd still like to see exactly how they loaded the the mail.jar and activation.jar

API Error

Vikas Sharma, October 22, 2003 - 8:02 pm UTC

Hi Tom,

Thanks,

If you want i can send you the complete description how i loaded classes and what error (output of loadjava) i got earlier by Email. It is not big abt 7k zip file.

Actually when i tried to load mail.zar on sys using loadjava i received few errors but then again i tried for second time, i did NOT get any error.

But my loadjava of activation.zar was finished with out any error on sys.

Thanks And Regards

Vikas Sharma


JavaMail on 9.2.0.4?

Doyle Freeman, October 23, 2003 - 10:53 am UTC

Is javamail still the best way to send an email with large attachments from pl/sql?
--
To be more clear about my specific issue.
--
I am creating an app with html db (love it by the way).
--
The user is able to select a file from their client machine and upload it. I then want to email that file to another party after I have done some validation on it thru pl/sql. I have a pl/sql package that gets fired after the file is uploaded that is reading the blob and verifying some business rules. If all of the business rules pass, then I want to email the blob as an attachment to another party.
--
Would you use the javamail through pl/sql to accomplish this, or is there a better way now?

Thanks

yes. it is the best way (until 10g)

java mail -- it is the best way.

Sending CLOB/BLOB with javamail

paul, October 23, 2003 - 11:02 am UTC

I dont do this with UTL_SMTP but we do it with javamail if you want to go back to that approach.

Here is some background.
a GTT gets populated with a list of external files and/or blobs, and/or clobs to attach to mail,
-we figure out mimetype based on extension.
-we use send_as_name to allow user to change filename of source document while sending.

the Java reads the GTT and for each record in resultset determines if File/Blob/Clob
[..]
if (rset.getString("file_type").equals("BLOB"))
{
MimeBodyPart mbp = new MimeBodyPart();
mbp.setDisposition(Part.ATTACHMENT);
mbp.setFileName(rset.getString("send_as_name"));
mbp.setDataHandler
(new DataHandler(new BLOBDataSource(rset.getBlob ("blob_data") , set.getString "mime_type"))));
mp.addBodyPart(mbp);
}
[..]
BLOBDatasource simply returns a binaryDatastream like so...
static class BLOBDataSource implements DataSource
{
private java.sql.Blob data;
private String type;
BLOBDataSource(java.sql.Blob data, String type)
{
this.type = type;
this.data = data;
}
public InputStream getInputStream() throws IOException
{
try
{
if(data == null)
throw new IOException("No data.");
return data.getBinaryStream();
} catch(SQLException e)
{
throw new
IOException("Cannot get binary input stream from BLOB.");
}
}
public OutputStream getOutputStream() throws IOException
{
throw new IOException("Cannot do this.");
}
public String getContentType()
{
return type;
}
public String getName()
{
return "BLOBDataSource";
}
}

Then we add the mp to the msg
msg.setContent(mp);

This was cobbled together from code here at asktom and also on OTN.
It will do fileattachments from o/s BLOBS (binarystream) and CLOBS (asciistream)

It might be easier to do the binary stuff this way than with CAST

Thanks Paul

Does anybody have any code for this, strictly using PL/SQL with javamail?
Sorry, reading java code is not my strength.

umm, yes, the original answer above is strictly using plsql with javamail. all of the code is there.

Is there ANY way to retreive email directly into the database?

load the java mail apis in there, and yes, you can read email.

or, if you use the collaboration suite, the database is email.

your smtp server is not configured to be a relay, it is not allowed to forward mail.

either

a) find someone who knows how to configure smtp and reconfigure your server to permit relays

b) use another smtp server.

Ken, November 27, 2003 - 1:29 pm UTC

Hi Tom,

Don't worry, my problem has been resolved, the problem was due to the wrong SMTP mail server name.

Thank you.



Sending Files as attachment

Jatinder, December 05, 2003 - 5:30 pm UTC

Hi Tom,

Just wanted to let you know that there's some information on TechNet that talks about using UTL_SMTP for sending emails with attachments.

</code> http://otn.oracle.com/sample_code/tech/pl_sql/htdocs/Utl_Smtp_Sample.html <code>

I am not sure if I follow how can I attach a document with the email. Basically, what I want to do is that we have a repositary of thousands of documents and the user can pick the document they want to have. Upon selection, the program should be able to email the selected documents to the user. Can you please let me know how I can achieve that using UTL_SMTP package.

Thanks in advance.

Tom Kyte
December 06, 2003 - 8:56 am UTC

i don't use utl_smtp for attachements, really hard.

i use the java mail api, demonstrated above. you send it a blob and away she goes.

utl_smtp

Ruben, February 07, 2004 - 3:16 pm UTC

Tom, How we can accomplish to send text to wireless
devices such as a mobile or pager?
It is possible via UTL_SMTP?

Thanks a lot for you reply.

Tom Kyte
February 07, 2004 - 3:52 pm UTC

sure, if you can email your stuff right now (like phone_number@skytell.com works) it is sort of obvious how to do it.

If you cannot, you might need something like 9iAS wireless that does SMS and other protocols.

Email Package

Steven Foskett, February 13, 2004 - 1:18 pm UTC

Hi Tom:

This was extremly straight forward and to the point. I was able to use your example and implement it very quickly.

Great Work

How to load

sreekanth gadhirjau, March 11, 2004 - 2:12 pm UTC

tom,

on 9.2.0.4.0 i did not load any classes explicitly. I just compiled. here is what happend.

we are running oracle 11i application on 8.1.7.4. We are in the middle of upgrading the database to 9i release 2. So we cloned the test system from production 11i system and then upgraded the database to 9i. now this one compiles in 9i but not in 8i.

Do i need to download the javamail api from sun site to load these classes? Please tell me how to load these classes.

thanks

Hi Tom,
Hope you can tell me why I may get this error?

what "email" program?? I mean, how does an email program fit into this?

what is ctl-f 1031 <enter>

sreekanth gadhiraju, March 13, 2004 - 10:12 am UTC

tom,

can you please explain ctl-f 1031 <enter> ?

thanks

search for 1031 on this page -- its been asked and answered in the past.

ctl-f should pop up the little "search" dialog
1031 is the number you want to search for
<enter> will do it (the search)....

I am having trouble in tacking the undelivered mails using SMTP.
Can you please advise me who can we tracke these

Tom Kyte
March 24, 2004 - 8:11 am UTC

when I send an email using utl_smtp from asktom

and it is not deliverable

it comes back to me, in my inbox. The error will goto whomever "sent" it (you can use an errors-to: record as well, or something like that, you'd just google the smtp protocol and see what options you have)

Soooo, whatever you are using in the from should be getting the "bounce". I sure do :)

guess you got bored reading after the first paragraph or two?

Loading and using the JavaMail API

In order to use the UTL_SMTP package, you must already have a Java enabled
database in Oracle8i. This is because UTL_SMTP relies on UTL_TCP and UTL_TCP in
turn is built on Java functions. (Remember, if you don't have a Java enabled
database you can use UTL_HTTP as described above to send simple emails). So, if
you are able to use UTL_SMTP, you must have a Java enabled database, we can go
to the Sun website and download their JavaMail API. This will give us the
ability to send much more complicated emails from the database; including
attachments.
The following is based on work performed by a coworker of mine,
Mark Piermarini who helps me out with lots of my Java issues.

PLSQL Mail routine vs Java

Barry Chase, April 29, 2004 - 12:37 pm UTC

The article was very helpful, however it leaned towards JavaMail as the end all solution. Unfortunately, I am not at liberty to get that installed on our AIX platform here for a number of non-technical reasons.

Through some net scouring and laborious hours of effort of my own, I came up with a PLSQL solution which handles attachments (including binary) and produces formatted emails.

I would be happy to share it with the masses, but I don't know how to get it posted it here for others to use. I also have a PLSQL FTP solution, which contains binary support as well.

I have the code at my website, and I would post it here, but I don't want to be seen as posting inappropriate material in the forum.

Any suggestions on what I can do to share my code with others ?

Tom Kyte

just plug a URL in here -- it'll become a link. no worries on that.

Pure PLSQL solution for Email and FTP (both with binary support)

Barry Chase, April 30, 2004 - 10:52 am UTC

Thanks for letting me share this. Any feedback would be welcome.

I have been working on my package solutions for Email and FTP routines for close to a year now. I have posted my updates in the downloads area of my website

</code> http://www.mylxhq.com <code>

The initial code was gleened from the web from elsewhere, but I provide a number of enhancements that took the routines to the next level and made them production ready. Below are some sample scripts that can be used to test the packages. The mail package header needs to have your mail server inserted in it before you compile it though.

Assuming that you have have compiled in the FTP and Email Packages that I have prepared, you can then use the following sample script to email a text file and email a binary file.

/* Formatted on 2004/04/09 14:06 (Formatter Plus v4.8.0) */
DECLARE
l_rows NUMBER;
l_sql VARCHAR2 (32000);
p_status VARCHAR2 (32000);
p_error_msg VARCHAR2 (32000);
p_elapsed_time VARCHAR2 (100);
p_bytes_trans NUMBER;
p_trans_start DATE;
p_trans_end DATE;
l_blob BLOB;
l_blob_len NUMBER;
BEGIN
hum_mail_tools.mail_files
(from_name => 'admin@mylxhq.com'
, to_name => 'bsc7080mqc1@mylxhq.com'
, subject => 'MAIL_FILES :: Sample TXT file'
, MESSAGE => 'Local DB Server ascii attachment in email.'
, priority => 3
, filename1 => '/xfer/INTF0047/sample.txt'
, DEBUG => 0
);
--
l_blob :=
hum_mail_tools.get_local_binary_data (p_dir => '/xfer/INTF0047'
, p_file => 'sample.pdf');
l_blob_len := DBMS_LOB.getlength (l_blob);
hum_mail_tools.mail_files_binary
(from_name => 'admin@mylxhq.com'
, to_name => 'bsc7080mqc1@mylxhq.com'

, priority => 3
, filename => 'sample.pdf'
, binaryfile => l_blob
, DEBUG => 0
);
DBMS_OUTPUT.put_line ('fini');
END;

To perform FTP operations of PUT and GET, you can follow this sample script.

To perform DELETEs and RENAMEs isn't much different. I have only tested the binary ftp support with zip files, and it works just fine. I haven't found an upper file size limit yet.

It is important to note that in order to handle binary files it requires some to setup Database Directories in Oracle which refer to physical drive locations. This gives Oracle the correct permissions to read files from the filesystem.

Anurag, May 06, 2004 - 8:52 am UTC

actually, I wanted to write event based triggers, and would like to send db acute problems(db server messages) on my senior and mine mobile as sms eg. instance crash, block corruption, locking etc. We are unable to work on its algorithm.



Tom Kyte

use OEM (enterprise manager) -- it has such hooks.

otherwise, you will be scripting this yourself. figuring out how to talk to sms (easiest way for me is, well, email -- email my phone number a message).


virtually every off the shelf monitoring tool, of which there are hundreds, does this out of the box.

multiple email addresses in a variable doesn't seem to work

ht, May 09, 2004 - 3:08 am UTC

Tom,
I get this error when trying to use a variable that contains " 'a@y.com','b@y.com' ":

ERROR at line 1:
ORA-29279: SMTP permanent error: 553 malformed address:

As your example proves, hardcoding the array works fine:

pkg1.send_email
(
in_from_email => 'x@y.com',
in_from_alias => 'X <'x@y.com'>,
in_to => test_mail_pkg1.array
--'a@y.com','b@y.com', <-- works fine
(l_addresses), <-- doesn't work
in_cc => pkg1.array('c@y.com'),
in_bcc => pkg1.array(d@y.com'),
in_subject => 'this is the subject',
in_body => 'this is the body'
);

What am I missing here? I also reviewed your example that uses a cursor to loop through each address but:

1. I would like to have all email addresses shown in the "to:" label so the addressees know who else received the email.
2. My data is stored in the db as a string (a@y.com,b@y.com, ...).

TIA

Tom Kyte
May 10, 2004 - 7:43 am UTC

you have to PARSE THE STRING into array elements -- each name gets a RCPT call.

a,b -> invalid emails

a
b

are "ok emails"..... You have to send an array, not a single string. if you want to send a single string, parse it in the lower level routines around the commas.

Sending a string (not an array) works fine.

Basic question about using dbms_job inside of a trigger.

ht, May 14, 2004 - 2:53 pm UTC

Tom,
This is a very basic question. I'm trying to use dbms_job inside of a trigger to execute dbms_job. As you advised, this will prevent emails from being sent (using utl_smtp) before the update is commited.
I cannot figure out how to create the trigger using dbms_job and I'm sure it's something "basic" that I'm missing.

do you have access to expert one on one Oracle? I have lots and lots and lots of examples in there (appendix on dbms_job and utl_smtp)

basically -- none of that is "trigger code", it looks like a mixture of sqlplus (variable, :x) and plsql.


I'm afraid to give you a code snippet here as there seems to be a misunderstanding of plsql vs sqlplus totally. I don't want to send you down the wrong path .

did you:

Tom Kyte
July 01, 2004 - 7:42 pm UTC

try a different client and see if it is because your client does not conform to the standard.

If not, you can always use utl_smtp and just "do it yourself", it is very easy (see above)

<Message>

I get the same in both IE and Mozilla Firefox. One of my friend used the same code to send me the mail from his Mailserver and it comes just fine. So is there something wrong with my Mail Server?

Empty Message

Reader, July 29, 2004 - 11:35 pm UTC

Hi Tom,

I tried the said things, but I still get a mail to my account with
<Message>
Error Reading Message or message with NULL body!!
</Message>

So I tried from Oracle 10g with UTL_MAIL.SEND, and voila!! it worked just fine.I am able to get the Subject as well as the body of the mail properly, but using the same procedure from 10g also did not work. So now I am really up against the wall.
By the way my Oracle Version for the previous attempt was Oracle 9i Release 2,from a Linux and Windows Box(from where I am getting the Empty Message).
Any chances of solving the problem ?

Thanks and Regards

Tom Kyte
July 30, 2004 - 7:36 am UTC

if you did that with telnet and you got that -- problem is somewhere on your end -- with your smtp / email client setup. we've removed Oracle from the loop entirely and are just using standard, documented, reliable SMTP commands. sorry.

It is an excellent information but not useful to me

A reader, August 10, 2004 - 5:05 am UTC

It is an excellent information. But it is not useful to me. I am sending an email through oracle stored procedure but it doesn't support html formatting. When a mail goes uses find the html tags etc. in the mail

So How do I solve. I have tried hardly But yet didn't get success. So can you help earlies

Thanks

Yogesh, August 19, 2004 - 4:37 am UTC

Does this specification / information applies to oracle 8.0? If not, then how can we send mail from oracle 8.0?

Tom Kyte
August 19, 2004 - 9:44 am UTC

it is very very difficult.

going into the way back machine.....

there is no utl_smtp in 8
there are no external procedures in 8
there are no java subroutines in 8

there is however utl_file and utl_http. so, what i've done in times gone by is:

a) use utl_file to create a uniquely named file with the email in it.
b) write a cgi-bin script that runs under the webserver that takes the name of the person to email to and the name of the file to email
c) send the mail from plsql via utl_http.request( '</code> http://127.0.0.1/cgi-bin/send_mail?p_name=....&p_file=.....' <code>);

I use 127.0.0.1 because the webserver must be running on the server (to be able to see the utl_file file) and I don't want just any john doe to be able to send email as if it was "oracle" on this machine.


You can also just do

a) use utl_file to create a uniquely named file that includes the target email address
b) use a cron job to periodically pick up all "spooled" files and send them.

Randy, August 19, 2004 - 11:44 am UTC

Tom,
I set up your JavaMail API from your book and when I execute I receive the following error:

ERROR at line 1:
ORA-29531: no method send in class mail
ORA-06512: at "SYS.SEND", line 0
ORA-06512: at line 6

Any thoughts on this?

Thanks!

Randy, August 19, 2004 - 12:12 pm UTC

Disregard last question, works great! Changed BLOB to BFILE in java source mail and problem was solved.

Randy, August 20, 2004 - 10:57 am UTC

Tom,
Any idea why the javamail API adds an extra space to my attachments? The spacing is not an issue when I view the files on the server. Attachments are sent from BFILEs. I wonder if anyone else has encountered similar problems.

use the same approach documented above with telnet to reproduce without utl_smtp at all.

Followup using telnet

A reader, August 24, 2004 - 11:55 am UTC

Hi Tom,

As per your suggestion, I used telnet to try the SMTP connection. This is what happened. I did the following:

C:\>telnet smtp.1and1.com 25

The response was
Connecting to smtp.1and1.com...
220 Welcome to Nemesis ESMTP server on mrelay

and then it is just waiting at this point and I was not able to type anything after this.

pls help.

Thanks.

Sending e-mail to multple recipients

Muneer Raza, September 01, 2004 - 10:20 am UTC

I am using Tom'example to send e-mail to multiple recipients. It works fine if I hard code the e-mail address
p_to => mail_pkg.array( 'mraza@beckman.com','rramanan@beckman.com' ).
But If I pass the more than one recipient e-mail address it fails with the following error message.

Cause: FDPSTP failed due to ORA-29279: SMTP permanent error: 501 Syntax error, parameters in command "RCPT TO:'mraza@beckman.com','rramanan@beckman.com'" unrecognized or missing
ORA-06512: at "SYS.UTL_SMTP", l

I also tried the following, but no luck, got the same error
l_user := '''mraza@beckman.com''' || ',' || '''rramanan@beckman.com''';
p_to => mail_pkg.array(l_user),



Tom Kyte
September 01, 2004 - 10:52 am UTC

if that is how you are passing multiple recipients, it is no wonder it fails.

you just send an email to the SINGLE user

'x@y.z,'r@a.b'

when you probably meant to send an email to two individuals.


soooo, put the recipients INTO AN ARRAY

l_user.extend;
l_user(l_user.count) := l_user1;
l_user.extend;
l_user(l_user.count) := l_user2;
.....

what does your connection type have to do with the version of Oracle you are using?

if you don't have write_raw_data, you won't be using that API, you need "more current software".

Problem with charset in JAVAMAIL

Violeta, December 10, 2004 - 5:04 pm UTC

Hi, Tom,
Thank you, this article was very usefull for me! But I have problems with JAVAMAIL.

I use character set "BLT8MSWIN1257" and when I send mail with attachment, body of recieved mail is OK, but I can not read attached text file.

I had to use attachmentData in CLOB, so I've modified your code, so this is my code:

"public static oracle.sql.NUMBER
send(String from,
String to,
String cc,
String bcc,
String subject,
String body,
String SMTPHost,
oracle.sql.CLOB attachmentData,
String attachmentType,
String attachmentFileName)
"


I replaced "oracle.sql.BLOB" to "oracle.sql.CLOB".
I added additional class:




" static class CLOBDataSource implements DataSource
{
private oracle.sql.CLOB data;
private String type;

CLOBDataSource(oracle.sql.CLOB data, String type)
{
this.type = type;
this.data = data;
}

public InputStream getInputStream() throws IOException
{
try
{
if(data == null)
throw new IOException("No data.");

/* return data.getAsciiStream();*/
return data.getCharacterStream();

} catch(SQLException e)
{
throw new
IOException("Cannot get input stream from CLOB.");
}
}

public OutputStream getOutputStream() throws IOException
{
throw new IOException("Cannot do this.");
}

public String getContentType()
{
return type;
}

public String getName()
{
return "CLOBDataSource";
}
}
"
Then I replaced "BLOBDataSource" with "CLOBDataSource",
but attached text file is undecipherable. What Did I wrong?

Thank You very much.

email doesn't understand "non standard charactersets" (well, it may well, but I'm no smtp expert)

basically -- things like that would need be base64 encoded (7bit ascii data) to be transmitted.

FYI for UTL_SMTP if via Web Form

Meyer, December 14, 2004 - 1:35 pm UTC

This is an FYI for those using UTIL_SMTP as a building block in their apps....

I just found this out today (after one of my app's had been in production for years working fine)...new problem, debugged it and thought this could save others some steps as I first looked at the network, firewall, relay settings based on googling the error mesg.

As a part of SMTP, a period "." on its own line in the data/body (SMTP DATA COMMAND) tells SMTP the body text is done....(CRLF.CRLF)

If a person fills out a form on your site...and that form text becomes emailed text....and if that person put a period alone on its own line in that form they wrote...it causes an SMTP error (all text following the "command" in the email body becomes invalid SMTP commands).

The solution I found was add a space after any periods that are followed by a newline in the text before I give to SMTP....(space between the perod and the newline)...it looks the same in the email but it not the CRLF.CRLF command

replace(
THE_BODY_BLOB,
'.'||chr(13),
'. '||chr(13)
);

This takes place on all the periods in the body...but only "Fixes" it if the period starts the new line.

Hope this helps.

Thanks,
Meyer

worked for me.

It is highly unlikely your smtp server is actually running on localhost however. And if it were, it is really unlikely others would allow it to relay through them.


This has nothing to do with Oracle right now, you need to find out what your smtp server configuration on your site really is (eg: go into your email client and see what smtp server your email client is configured to use)

A reader, December 16, 2004 - 11:24 am UTC

Tanveer,

It is not working for me too. What TOm says should be true as, the same thing was wroking at my earlier clients place.
I am not able to figure out how to fix this though...

Let me know if you find something!

Thanks!

I cannot reproduce and have never seen that.

the only remotely similar thing I see is with shared server connections (it is similar only).  Are you using shared server, does it reproduce when you use a dedicated server. 

Just to share.........

Sikandar Hayat Awan, December 29, 2004 - 10:30 pm UTC

Hi,
I found a bug ralted to utl_mail in 10g posted on metalink so thought to share it with all of.

Hi,
Installed utl_mail package, set the smtp_out_server parameter in the init.ora and tried sending mail using the following example.

begin
utl_mail.send(sender=>'testd',recipients=>'satish.iyer@abc.com,subject=>'test message',message=>'Text message only',
mime_type=>'text/html');
end;

I am receiving the mail okay, however the sender, recepient and the subject in the mail are preceeded by the database character set.
Like this...
"=?US7ASCII?Q?testd?=@lgis2000.abc.com"

--- Oracle Response ----
This is due to bug 3506588 which is fixed in upcoming release of Oracle 10G. Currently backports for this bug do not exist.

Sending to many one by one using utl_smtp

Hi Tom
The solution you wrote 2/3 years ago was very helpful
but I have a a problem when sending to many recipients. I call the send procedure and pass some arguments which are different addresses then at some stage it will give me the ff errors.
ORA-20001: 421 Server too busy
and then after that it will give....

Is there a way of keeping the UTL_SMTP working and ready to receive more requests..

ask your system admins, this is a problem with your smtp server itself -- nothing in the database.

UTL_MAIL

a reader, February 02, 2005 - 5:23 pm UTC

Hi Tom,

I have been looking into sending attachments using Oracle 10g. Could you explain me the following lines, in context with the operational notes given below.

"However, if SMTP_OUT_SERVER is not defined, this invokes a default of DB_DOMAIN which is guaranteed to be defined to perform appropriately."

Operational Notes
You must both install UTL_MAIL and define the SMTP_OUT_SERVER.

To install UTL_MAIL: 
sqlplus sys/<pwd>
SQL> @$ORACLE_HOME/rdbms/admin/utlmail.sql
SQL> @$ORACLE_HOME/rdbms/admin/prvtmail.sql


You define the SMTP_OUT_SERVER parameter in the init.ora rdbms initialization file. However, if SMTP_OUT_SERVER is not defined, this invokes a default of DB_DOMAIN which is guaranteed to be defined to perform appropriately.

Thanks in advance, 

Tom Kyte
February 03, 2005 - 1:37 am UTC

it is saying "if you don't set the smtp out server, we'll use what we find in the db_domain parameter - and that is probably not your smtp server so set the smtp out server parameter so mail can actually be sent"



possible workaround for empty mail messages.

G.J. Ruiter, February 03, 2005 - 8:52 am UTC

Subject: possible workaround for empty messages.

Hello Tom,
Two people mentioned that they got an empty message(
May 13, 2003 and July 29, 2004)

I had the same problem, but here everything after a blank line was sent.
message:='line1'||crlf||crlf||'line2'||crlf||'line3';
and I received:
------------

line2

line3
------------
This also happened when I tested using Telnet, only data after a blank line was sent.
We use Microsoft Exchange Internet Mail Service 5.5.2657.72), the problem does not occur when I send mail to other accounts which probably use other mail servers.

Also; here everything works when I start my message with a blank line.

Yours sincerely,

G.J. Ruiter.


Email Validation

Ray DeBruyn, February 03, 2005 - 12:38 pm UTC

Using utl_smtp, you make a connection to the email server and essentially run commands. The utl_smtp package has a function to validate the email, the problems are that you need permission on the email server to run the command and the task requires connecting to the remote server to validate the email. If you wish validate 100 emails, it could be time consuming, but it could be used to validate an individual email as it is inserted or updated.
Validating against the email client assumes that this email is in your address book.

I don't see all followups to every review -- and I tend not to re-read the page when I get new ones (so if there isn't any reference to something above, I don't really put them together...)


can you see support note

whizkid, May 03, 2005 - 3:08 am UTC

Tom, that note is not accessible to me. It says your search returned no hits. Maybe its an internal document. Can you copy & paste the contents here? or can you email it to me?

Thanks a lot!

How to email multiple attachments to multiple people with JavaMail API

Yai, May 09, 2005 - 5:37 pm UTC

Hi Tom,

I learned from your Expert one-on-one how to email to multiple people using utl_smtp. Now I want to email multiple attachments to multiple people. You suggested JavaMail API if attachments were involved, but how can I email multiple attachments to multiple people?

Thank you very much.

Tom Kyte
May 09, 2005 - 5:51 pm UTC

code is all here, you just need to modify it to suit your needs.

NoSuchProviderException

Stacey Jones, May 10, 2005 - 2:39 pm UTC

I resolved my previous exception. I was using a newer version of the mail class than you used. Downloaded the older version and got past that error but now when I run this test block:

declare
ret_code number;
begin
dbms_output.enable( 1000000 );
dbms_java.set_output( 1000000 );
commit;
ret_code := send(
p_from => 'rsjones@ups-scs.com',
p_to => 'rsjones@ups-scs.com',
p_cc => NULL,
p_bcc => NULL,
p_subject => 'Use the attached Zip file',
p_body => 'to send email with attachments....',
p_smtp_host => 'winsmtp.ups.com',
p_attachment_data => null,
p_attachment_type => null,
p_attachment_file_name => null);
if ret_code = 1 then
dbms_output.put_line ('Successfully sent message...');
else
dbms_output.put_line ('Failed to send message...');
end if;
end;
/

I get this error:

I checked Metalink and it mentioned that the CLASSPATH needed to be updated with the location of the classes, did that and got the same result.

Yes.
Tom Kyte
May 10, 2005 - 11:17 pm UTC

sorry, never have encountered that problem myself. setting the classpath won't do a thing (the database has its OWN environment)

Stacey Jones, May 11, 2005 - 8:39 am UTC

I forgot to mention I'm on 8.1.7.4 on HP UX. What versions of the mail and activation jar files did you download from Sun? Any other suggestions? Should I open a TAR?

Tom Kyte
May 11, 2005 - 8:56 am UTC

really old ones. (this thread is about 4 or 5 years old)

You can try a tar but I'm doubtful it would go very far - you are loading 3rd party code into the database as an application -- if all of the bits and pieces are not there, not much we can do.

appointment/meeting request from DB

Thanks


Tom Kyte
June 01, 2005 - 11:28 am UTC

not really, you'd have to tell me how to create an MS outlook appt/meeting first.

Re: appointment/meeting request from DB

A reader, June 02, 2005 - 3:03 am UTC

Can we call MS DLLs (using external proc) for achieving the same? If so, it would be great to get an example from you?

Thanks


Tom Kyte
June 02, 2005 - 4:35 pm UTC

I don't do windows.

But if you have expert one on one Oracle -- I have a rather EXTENSIVE chapter on how to do extprocs.

If you search this site, there are lots of examples


And they are well documented -- how to setup, use etc.

You have to write the integration code, your layer to be called from the database, I cannot do that.

Problem with execution

Byron Ward, June 06, 2005 - 3:57 pm UTC

When I execute this statement:

begin
afm.mail_pkg.send
( p_sender_email => 'sender@domain.com',
p_from => 'Oracle Database Account < oracle@domain.com >',
p_to => mail_pkg.array( 'user@domain.com','user1@domain.com' ),
p_cc => mail_pkg.array( 'user2@domain.com' ),
p_bcc => mail_pkg.array( 'user3@domain.com' ),
p_subject => 'This is a test',
p_body => 'Hello, this is the mail you need' );
end;

I get the following error:


afm.mail_pkg.send
*
ERROR at line 2:
ORA-06550: line 2, column 9:
PLS-00306: wrong number or types of arguments in call to 'SEND'
ORA-06550: line 2, column 9:

ORA-06550: line 2, column 9:
PLS-00306: wrong number or types of arguments in call to 'SEND'
PL/SQL: Statement ignored

It seems to be a problem with the array, but I can't get it to accept it. If I take the arrays out and switch them to varchar2, I can send just fine. But this eliminates the funcionallity of multiple recipients that I need.

Any thoughts?

Thank you,

Byron


Tom Kyte
June 06, 2005 - 5:49 pm UTC

well, if you need to use afm.mail_pkg to call it, why not to reference the array?

are you logged in as AFM?
if not, do you have your own copy of mail_pkg in your current schema?

if you use the right type, afm.mail_pkg.array( .... ) what then?

Duh!!

Byron Ward, June 07, 2005 - 5:31 pm UTC

Sorry about the post.... I must be an idiot.

I can't believe I missed such a minor thing.

Why ñ/Ñ character are not displayed?

Eduardo, June 17, 2005 - 6:05 am UTC

Hi, I´m using the standards DEMO_BASE64 and SEND_MAIL packages for sending email through Oracle9i. But in Spain we have a special character (ñ). If I send an email using this special character I wouldn´t view it.

Can you help me?

Best Regards

Tom Kyte
June 17, 2005 - 2:58 pm UTC

if you base 64 encode the 8 bit data, it should transmit just fine. What do your recieved email headers look like? what is the character set of your database.

Thanks, that works fine. I changed the write_data by write_raw_data



Client (Outlook) and Database in diferent language

Ricardo Patrocínio, June 29, 2005 - 8:49 am UTC

Hello Tom,

When I send e-mails to users with the e-mail client in a different language than the language in the database this client's can not understand the Date in the e-mail and always assume it to be January.

This is happening with a Database in English and a Client in Portuguese.

How can I solve this issue?

Tracking Bounce Emails

Ravi Kumar, October 13, 2005 - 7:25 am UTC

Hi Tom..

It is very very useful thread for me, I have read about the UTL_SMTP package and applied in my project to send emails from our Application. And It is working fine, thanks to you :).

Now I need to do something to track bounced emails.

Currently My Application sending the emails like this.

1. Selection Screen (From Where we can select the persons to send an email)

2. Inside the loop I am sending the emails to the selected persons one by one and generating a History Sequence No for each email and storing the details in Email_History Table.

Now What I want to do is..., I want to send this History Sequence No with each email in a Hidden way, So that if the mail bounce back, I can get this History Sequence No Back and can trace it in my History Table. can you please suggest me what is the best method to do that. (I mean How to send the History Sequence No with each Email so that I can get it back in all type of bounces)

Thanks & Regards
Ravi Kumar..



net send through the db

Dan, October 19, 2005 - 9:29 am UTC

In our development environment, whenever someone wants to take down a database they do a "net send *" which alerts a lot of people whether or not they care about this...
I tested to see if "net send /users" knew about database sessions and it didn't.
Is there any way to throw a message to the screen of everyone that has a database session?

Tom Kyte
October 19, 2005 - 9:44 am UTC

you'd have to query the database and feed that to "net send".

net send through db

Dan, October 19, 2005 - 9:57 am UTC

OK, so I've got this:

DECLARE
CURSOR c
IS
SELECT DISTINCT osuser
FROM v$session
WHERE osuser != 'SYSTEM';
BEGIN
FOR r IN c LOOP
host (net send '||r.osuser||': database going down');
END LOOP;
END;
/

but I've tried a couple variations of the actual "net send"
part of it, and can't find any that are legal...

Thanks.

Tom Kyte
October 19, 2005 - 12:30 pm UTC

there is no "host" command in plsql persay, a sqlplus script could be:


set feedback off
set heading off
set pagesize 99999
set trimspool on
set echo off

spool tmp.sql
begin
for x in ( select distinct osuser from v$session where osuser <> 'SYSTEM')
loop
dbms_output.put_line( 'host net send ....' );
end loop;
end;
/
spool off
@tmp.sql


(not tested, but the gist is there...)


Email within 10g

Jasbir Kular, October 19, 2005 - 8:06 pm UTC

Hi All,

10g comes with JavaMail and I was able to compile and run the "mail" java program provided at the beginning of this thread without having to loadjava the Sun javamail classes. I wanted to do this because UTL_MAIL seems limited to only RAW and VARCHAR2 attachments. I wanted to easily use BFILE attachments. The "mail" java program provided by Tom and his team is excellent and I think that program or some variation of it should be used for the implementation of UTL_MAIL. The current form of UTL_MAIL seems like a layer on top of UTL_SMTP.

Thanks.


Required some clarification

Mousumi Ghosh, October 20, 2005 - 7:10 am UTC

When we attach a file in case of sending e-mail from pl/sql
we can use
1.SYLK file format.
2.HTML
Using HTML we can create the file and format it as we required.
Then why should we use SYLK file format.
I am working in Oracle 10g.
Is it for the older version of Oracle where we can't use HTML in PL/SQL code? or for all versions of Oracle we can use HTML.
Please clarify why should we use SYLK file format?

Tom Kyte

me
 

Randy, November 14, 2005 - 11:26 am UTC

Tom,
I have a question about using the date with DBMS_JOB. I have the following code in my HTML_EMAIL procedure.


------

select sessiontimezone into timezone_ora from dual;

timezone_info := substr(timezone_ora,1,3) || substr(timezone_ora,5,2) || ' (GMT)';

l_date := to_char(SYSDATE,'dd Mon yy hh24:mi:ss')|| timezone_info;

l_connection := utl_smtp.open_connection( p_smtp_hostname, p_smtp_portnum );
utl_smtp.helo( l_connection, p_smtp_hostname );
utl_smtp.mail( l_connection, p_from );
utl_smtp.rcpt( l_connection, p_to );


l_temp := l_temp || 'Date: '|| l_date || chr(13) || chr(10);
l_temp := l_temp || 'MIME-Version: 1.0' || chr(13) || chr(10);
l_temp := l_temp || 'To: ' || p_to || chr(13) || chr(10);
l_temp := l_temp || 'From: ' || p_from || chr(13) || chr(10);
l_temp := l_temp || 'Subject: ' || p_subject || chr(13) || chr(10);
l_temp := l_temp || 'Reply-To: ' || p_from || chr(13) || chr(10);
l_temp := l_temp || 'Content-Type: multipart/alternative; boundary=' ||
chr(34) || l_boundary || chr(34) || chr(13) ||
chr(10);
-------------------------------------------------------

When I execute the HTML_EMAIL procedure directly within SQLPlus the date in the mail client is correct. However, when the procedure is called using DBMS_JOB next_date, next_sec the date always comes back 1 day behind at 7:00 p.m. I can not understand why DBMS_JOB would be causing this change. Any thoughts on this?

Thanks,
Randy

Tom Kyte
November 14, 2005 - 2:08 pm UTC

you do not show the dbms_job call???!?! that is the only important part here.

A reader, November 15, 2005 - 8:35 am UTC

The dbms_job only calls the procedure. For example,

declare jobno number;
BEGIN
DBMS_JOB.SUBMIT(jobno,
' begin
PEOBCT_WSAR;
end;', TRUNC(SYSDATE) + 05/24, 'NEXT_DAY(TRUNC(SYSDATE), ''MONDAY'') + 05/24');
END;

The PEOBCT_WSAR sends out the email messages..

as
begin
html_email(
p_to => 'user',
p_from => 'from database',
p_subject => 'subject',
p_text => 'WSAR can be viewed in HTML',
p_html => 'email message from database....',
p_smtp_hostname => 'smtp.server',
p_smtp_portnum => '25');
end;

When I run the dbms_job manually the date/time is correct in the client. When Oracle runs the DBMS_JOB the date/time is incorrect and always one day behind @ 7:00 pm. That is the part that makes no sense to me...

Tom Kyte
November 15, 2005 - 11:39 am UTC

show me what you mean by "incorrect" - are you saying the next_date is getting set wrong.

It seems that next date would ALWAYS be a monday at 5am. show me what you see.

A reader, November 15, 2005 - 12:50 pm UTC

The dbms_job next_date is correct. The date that displays in the email client is not correct. The date in the client is correct if I run the procedure and/or dbms_job manually. It is not correct - off by approx 1 day and always 7:00 p.m. - in the email client.

Thanks,
Randy

The information is very very useful. But what I see is that the mails can be send to same domain, like if I can send mail from abc@xyz.com to pqr@xyz.com, but if I want to send mail from abc@xyz.com to abc@pqr.com

Please advice.

Thx ... Bids

ask your network/system administrators - they are the ones that configure the SMTP servers. They have undoubtedly disallowed relaying in order to not be used by spammers.

ORA-29278: SMTP transient error: 421 Service not available

Ram, December 17, 2005 - 10:09 am UTC

Hi,
My client wants to address a section of Customers, and wants to send promotional mails. I have written a procedure for sending mails. I am picking the recepient email ids from the database. My procedure runs fine, if addressed to a small number of customers (say upto 1000), when increased, I get this error

talk to your SA or network guys, you do not have a SMTP server setup at the place you are trying to get to. You need to ask them "so, what is the correct host name and port number for me to use to send email over SMTP from this server?"

SMTP issue

Ram, December 19, 2005 - 4:42 am UTC

Actually, I am able to open, handshake and close connections (without any text messages, only the connections), through the same procedure. The connection is getting established 'n' number of times I am scheduling it for. But, when the message to be sent is being put, it sometimes sends 800 mails or sometimes 1 mail, after which the connection hangs. I am establishing the connection in the loop for every record. I also logged only the records that are being fetched, without the connection, and it is also working fine, which means there is no issue with the procedure.
Is there any issue in sending from a db which is shared server?

Regards,
Ram

you are hitting your smtp server too hard and fast then, it cannot keep up. sleep for a bit between emails, give it a chance.

problem *not* in database.

email

mo, February 13, 2006 - 5:47 pm UTC

Tom:

1. Is there a way to confirm if the email was sent from the smtp server to the destination and track that?

2. Does this package success means that the email was sent to the smtp server only but you do not know what happens afterwards (reached destination)?

thanks,

Tom Kyte
February 13, 2006 - 5:51 pm UTC

1) hah, no.

2) correct. It does not mean the recipient will ever actually get it, as with all email

Tom,

What is the number of characters allowed to pass a value to the parameter p_send_email for the "utl_smtp.mail(g_mail_conn, p_sender_email)".

Thanks,

Error to get POP3 mail

Kato, February 24, 2006 - 11:18 am UTC

Hi Tom:

I want to read POP3 mails with a PLSQL function, then i loaded the java mail apis into Oracle Database 9i R2. and gave this grants:

Attach File Direct to mail

ummm, well, don't know what to say here.


You are not running "outlook" or whatever you run on your pc in the database right...

and given that outlook or whatever just lets you pick a file from the operating system....

and that a file is just another word for "blob" in effect.


tell me - what is meant by "attacht directly with mail"???? that doesn't compute.

and remember, we are writing software here, to run in the database, not pushing buttons on a gui.

talk to the guy that installed the software, they must have read the installation guide right - they know how to use dbca and add/remove software components.

HTML emails

Emad Kehail, June 05, 2006 - 2:31 am UTC

Thanks Tom for this great idea. I have used successfuly with attatchements.

However, I could not send HTML formatted emails using JavaMail API.

How could I send attachments along with HTML emails using the JavaMail API???

Thanks in advance

Tom Kyte

search this site for html email

the html is "an attachment"

Sending too many emails take so long time

Emad Kehail, June 06, 2006 - 7:18 am UTC

Thanks Tom for your quick reply. I have already used the package developed at

</code> http://www.oracle.com/technology/sample_code/tech/pl_sql/htdocs/Utl_Smtp_Sample.html <code>

to send emails from Oracle. I am sending HTML formatted emails, either with attachements or not.

However, when I try to send emails to many recipients, say 10,000 emails, it takes so much time.

I have followed your idea and I have submit it as job, but I have noticed that this job took 11200 sec to send 10000 emails.

I have disabled the line that sends the email and I have ran the job again, it took only few seconds (2-3 seconds only).

My friend has told me this could be because of the handshaking the UTL_SMTP package is doing with the email server. The UTL_SMTP package has to establish a connection each time it needs to send an email!.

I have optimized the code, so instead of sending indvidual emails, I have concatenated 50 emails, which is the maximum limit I can use, to send them as once as BCC. The speed improved, but just so little.

The time reduced from 11200 seconds to be 7349 seconds.

I have read in this thread that you are using this at Oracle to send thousands of emails daily.

Would you please point me where I could have done something wrong?? Where I can improve the speed of sending emails?

Thanks
Emad

Tom Kyte
June 06, 2006 - 8:46 am UTC

smtp *ain't fast* that way.

you sent 10,000 (thousands) of emails in about 3 hours. You just showed how that can happen?

You have done it correctly with the bcc - if you are sending the same exact email, you should bcc as many people as you can (send one email, not one email per person)

So, why just "50"?

Thanks

Emad Kehail, June 06, 2006 - 11:46 pm UTC

Thanks Tom for this quick helpful reply.

Regarding the 50 emails, it is because the university IT policy, where I work, has determined the maximum limit for any email sent to contain only 50 email addresses!!!. Unfortunately, this has been applied to the mailing system we have implemented.

Before, we were BCCing as many as we can and send the email as once.
Anyhow, you had, and still, make it clear for me where is the problem. I already expected it to be as I mentioned before.

Thanks again and again for your continuous help and efforts.

Emad

tell the university IT community that because of their rule, they need to buy you 10 more smtp servers.



Formatting in UNIX mails

Pretaish, June 07, 2006 - 12:52 pm UTC

Hi Tom,

Currently I am sending emails to my clients through sendmail utility of UNIX. These mails contain details of various stock market deals. Now, they want the email text to be formatted. E.G. the headers should be in Bolds..

Please let me know how it can be accomplished.

Hi Tom,

Java problems

Mike Friedman, July 03, 2006 - 6:58 am UTC

We're trying to implement this in a 10gR1 DB.

When we run the line

Transport.send(msg);

We throw an error - Exception: java.lang.ExceptionInInitializerError.

Note: We originally had other problems but we dropped the mail.zip and reinstalled with 1.3.1 and that went away.

Anyway, when we check dba_java_classes we see that javax/mail/Transport has Kind "INTERFACE". That can't be right - shouldn't it be a class?

Where can we go from here?

Do we also need to downgrade JAF?

Tom Kyte

the utl_mail package in 10g supports attachments, have you considered just using that rather than loading external java packages?

Yes Tom, I understood, but my question is if I use this code to read and encode a file in http place, how can I the same operation (read and encode), with which procedure for read an encode a file in a directory in a local pc ?
The code is :

req := utl_http.begin_request('</code> http://192.168.1.5/webShared/Attachm/'||PAttachment <code>;
resp := utl_http.get_response(req);

BEGIN

Thank you so much.

Tom Kyte
July 24, 2006 - 11:01 am UTC

I'll say it again: you have to get the file to the database server, unless and until you do - you will NOT be attaching it to anything coming from the database server!

It would be very virus like if we could reach back to your machine and just pick up any file we wanted wouldn't it.

Gladys, July 24, 2006 - 12:21 pm UTC

Thank you


Tom Kyte
July 24, 2006 - 2:51 pm UTC

now, I am really not following you.

"i cannot get nothing from my database server"?


I don't know what you mean. what does the http server have to do with anything??

if you are sending email via PLSQL - it starts with the database server, ends with the database server and never has anything to do with anything else other than the database server.

local pc - don't mention it, doesn't count, cannot access it.
http server (another server, any other server) - don't mention it, doesn't count, cannot access it.


it is all about stuff on the database server - that is all you have access to - period.

About mail

Gladys, July 31, 2006 - 10:16 am UTC

Tom, I have other question about mail. I have 9i data base, but I am working in 10g forms builder. I am trying to send email directly for report, and I am getting the error REP-50159. I am looking for in the report documentation, and I get this :
REP-50159: Executed successfully but there were some errors when distributing the output

This error can occur for a number of reasons when sending report output to an e-mail destination.

Cause 1: Mail server is not configured properly.

Action 1: Configure the mail server in the server configuration file (ORACLE_HOME\reports\conf\server_name.conf) and the Reports Builder configuration file (ORACLE_HOME\reports\conf\rwbuilder.conf). The pluginParam element should specify the outgoing SMTP server name. For example:

<pluginParam name="mailServer">smtpserver.mycompany.com</pluginParam>

For more details, refer to the chapter "Configuring OracleAS Reports Services" in Oracle Application Server Reports Services Publishing Reports to the Web.

Cause 2: The mail server is not responding or is not up and running.

Action 2: Check if the mail server is up and running and is responding in a timely manner. You can use your Microsoft Outlook client to connect to the mail server and check the status.

Cause 3: A valid recipient e-mail address is not specified for the desname keyword.

Action 3: Specify a valid recipient e-mail address for the desname keyword.

Cause 4: The mail server is SSL-enabled. SSL = Secure Sockets Layer

Action 4: Use a non-SSL mail server. Oracle Reports does not support SSL-enabled mail servers to send e-mail.

I checked all of causes, and everythig is ok in my server. I am sending to my own email address, the smtp server is well configurated, my mail server is workig ok, and it doesn't is a SSL mail server.
Could you give me any suggestion ?
Thank you so much

We have to authenticate at the mail-server. In our project this is a MS Exchange Server 2003 and we have to authenticate by username and password. In utl_smtp we use the commands:

utl_smtp.command(c, 'AUTH LOGIN');
utl_smtp.command(c, demo_base64.encode(utl_raw.cast_to_raw(i_username)));
utl_smtp.command(c, demo_base64.encode(utl_raw.cast_to_raw(i_pwd)));

Is there a similar way in your java stored procedure?

I don't know, I've never used MS exchange. This really isn't an Oracle question as all you need is "java" plus "MS exchange" to get it working - once you figure that out, we can load that java into the database.

My database is loaded on Linux 9.
for which i have written following code & give following permissions :-

grant javasyspriv to vinay;
dbms_java.grant_permission('VINAY','java.io.FilePermission','/usr/bin/mozilla','execute');

import java.lang.*;
class ExecDemo
{
public static void caal(String s)
{
Runtime r = Runtime.getRuntime();
Process p = null;
Thread t = Thread.currentThread();
try
{
p = r.exec(s);
}
catch(Exception e)
{System.out.println(e);}

}
}
CREATE OR REPLACE
procedure fexc(p_name IN VARCHAR2)
AS
LANGUAGE JAVA
NAME 'ExecDemo.caal(java.lang.String)';


when i'm executing this code on linux(where my DB is loaded)
it's working fine.
Begin
Fexc(‘/usr/bin/mozilla’);
End;

but when i execute this procedure from other system(say a client system with windows env.) it's not run mozilla.
what's the problem?
is any other permission required to call remote executable
file, but in my previous code (for deleting file) it's deleting file of remote machine.

umm, the code runs on the server, not on the client, even if you got iexplore to start, you would never be able to see it, it doesn't run as you on your terminal

What precisely are you trying to accomplish here?????

V K Ravi, October 04, 2006 - 7:36 am UTC

On our's ERP on some places i have to send sms to clients
which depends upon conditions, so i have to make that program in backend(it's working fine from Forms6i but after running that URL i havn't any control to close IE and it must require internet connection on client for that reason i have choose java).
For sending SMS i have to start IE on server with an URL.
after some time(say 1 or 2 sec.) IE will be closed. so my work will be done, but i hang here.I'll be very pleased if u help me out.
thx & regards
ravi

better find "a better more reliable" way to do this.

I serioulsy DOUBT you need IE

I think you might need something that can "do a url"
That could be utl_http

but IE will have absolutely nothing at all to do with it.



ravi, October 06, 2006 - 2:38 am UTC

Ok tom i know that this is not a proper solution,
and rightnow i'm trying to use java.net package.
Hope here i'l get solution.
But i still wondering whyn't my procedure was working if
i was executing procedure from client side.
is any priviliges missing? what's the reason?
thx
ravi

Tom Kyte
October 06, 2006 - 8:59 am UTC

umm, because IE is a "gui" that needs "a screen", and you don't "have one" in the database.


This ain't unix.

Read mails and write to a table

Nikhil, November 14, 2006 - 7:42 am UTC

Hello Tom,
I want to read an E-Mail, extract attachments (Text or Excel) and write it to a table.

Can you give me some suggestion or steps as to how to go about? I'm using Oracle 10g.

Thanks


Tom Kyte

well, when you have figured out how to read an email, extract the attachments - and have the attachments, we can help you out with getting them into a BLOB:

</code> http://docs.oracle.com/docs/cd/B19306_01/appdev.102/b14249/toc.htm <code>

Emu, November 15, 2006 - 1:07 am UTC

Adding attachments can be quite easy - when they are plain text anyway. I've been sending mulitiple attchments this way for ages safely without the need for hundreds of lines of code! So if your sending basic attachments probably no need to use the java library, just do it yourself using utl_tcp.

Really its simple enough and I'm sure you can google up an example. I did.

Sending Email form Developer 6i and Oracle 9i

Razaul Karim, November 20, 2006 - 5:21 am UTC

Mr. Tom,

I have followed UTL_SMTP accordingly for sending email from Developer 6i Forms. It is working well when I sending single line in message. But, I want to send multi-line message. When send the multi-line message then it is not working and giving the following error:

ORA-29278

Please give me a solution, I will be very grateful to you.


Tom Kyte
November 20, 2006 - 1:37 pm UTC

$ oerr ora 29278
29278, 00000, "SMTP transient error: %s"
// *Cause: A SMTP transient error occurred.
// *Action: Correct the error and retry the SMTP operation.


i guess retry, i mean, what else can one say - it is hard to debug your code without seeing your code.

and if your code is not TINY, we don't want to see it.

Great Help

Mandeep, November 23, 2006 - 4:27 am UTC

Dear Tom,
The example and steps given are the best help anyone interested in sending e-mail with attachments from Oracle can get. Thanks to you.

I am facing a little problem.. may be you can guide me on that..

I implemented the steps suggested in the example for sending e-mail with attachements from orcale 9i (Windows) and everything was working perfect.

Now, I implemented the same steps on Oracle 9i (Unix) in a different environment and different exchange server but the same application installation, the email is received without any body & attachments.

I compared the "Internet Headers" of the e-mails from two installations and there seems to be something missing in the later one.. have a look...

Mailing from Oracle 10g IDS

Arindam Mukherjee, December 01, 2006 - 6:07 am UTC

Sir,

The current setup is Oracle application server (10G) on Linux OS and Microsoft Exchange Is on Windows 2003 server. Application server configuration file is configured to point to the exchange server as an SMTP server. For any report (Oracle Reports - 10g IDS) when DESTYPE is MAIL and DESNAME as email address, works very well when email address is one of the addresses defined in local domain, but gives error when email address is not from the local domain. For example “hcl.in” is the local intranet domain. There is user with name Arindam Mukherjee in this domain. When I send mail to arindamm@hcl.in, it is sent successfully, but when I try to send to arindamkol@yahoo.co.in, I get an error.

Could you kindly help me have the solution?


Tom Kyte

talk to your network administrators, the smtp server you are connecting to is NOT allowed to send mail outside of your machine - this is done to prevent spammers from hijacking you.

You need to find out what your companies real smtp server is

can we detect for mail box full

rahul, December 05, 2006 - 2:25 am UTC

Hi Tom,

I was just wondering if using the error codes returned by utl_smtp can we find if the recepients mailbox is full.
Does the error code 552 means the same?

Thanks,
Rahul.

look up the specification for smtp?? we are just telling you what was returned, we don't make up the numbers - they are told to us.

BCC name

Parag J Patankar, December 05, 2006 - 11:16 pm UTC

Hi Tom,

Thanks for your excellent PL/SQL script for sending email. I have tried to send email with BCC option, it works fine. But I have noticed that person in mailing list of BCC receives mail, but he can not see his address in BCC.

Can you show me how to do this changes ? This query I am asking you because of academic intrest.

thanks & regards
PJP

Tom Kyte
December 06, 2006 - 9:37 am UTC

that is the point of bcc, to NOT see the address.

BCC option

Parag J Patankar, December 06, 2006 - 11:32 pm UTC

Hi Tom,

Thanks for your answer regarding BCC. But If send mail thru Lotus Notes, to myself with BCC option, I can see only my address at BCC. Can you show me how to do this change in your Oracle Code ?

thanks & regards
PJP

Tom Kyte
December 07, 2006 - 9:46 am UTC

nope, because BCC should not be seen - this has NOTHING to do with the Oracle code - this is "smtp" and the email client.

Is it an error or warning?

Possible to remove Message-Id: <blah blah> from message?

Paul Vanover, March 07, 2007 - 10:51 am UTC

Your examples are excellent. I just had one follow-on question. When I send a message, somewhere in the message (seems to vary) I get this:

Message-Id: <iss.798ba011.7dd7.45eed9b7.9fb19.ca@cpmx.mail.saic.com>

It is embedded within the message and it isn't exactly in a great place. In my latest example, it gets embedded after the first line of the message. It seems like it would be at the end or something.

Anyway, I was just wondering if there is any way to make that go away, or at least make it appear where I want it to appear in my message? Thanks so much for your help.
Tom Kyte
March 07, 2007 - 11:10 am UTC

we don't put that there, not from "us"

if your smtp server is putting it in the wrong place (that belongs in the header, should not be visible in the message itself), then there is something wrong with your smtp server.

Thanks for responding, I think I figured it out.

Paul VanOver, March 07, 2007 - 12:06 pm UTC

I think I figured out the problem. When you said it belonged in the header, you were right, of course.

I added this:
  -- Last header block.
  UTL_SMTP.write_data(l_mail_conn, UTL_TCP.CRLF || UTL_TCP.CRLF);


to my pl/sql and the problem went away. It was like I needed to take up an additional line in the header before starting my message text, or something like that. This is all new to me. Anyway, I included a snippet of how it is now and it is working perfect. It doesn't include the line I mentioned in my last message.

Thanks so much again for your help!

Paul
  UTL_SMTP.open_data(l_mail_conn);
  
  UTL_SMTP.write_data(l_mail_conn, 'From: ' || pFromEmailAddr || UTL_TCP.CRLF);
  UTL_SMTP.write_data(l_mail_conn, 'To: ' || pToEmailAddr || UTL_TCP.CRLF);
  UTL_SMTP.write_data(l_mail_conn, 'Subject: ' || pSubject || UTL_TCP.CRLF);

  -- Last header block.
  UTL_SMTP.write_data(l_mail_conn, UTL_TCP.CRLF || UTL_TCP.CRLF);

  UTL_SMTP.write_data(l_mail_conn, pMessage);

  UTL_SMTP.close_data(l_mail_conn);
 
  UTL_SMTP.quit(l_mail_conn);

Time Zone issue?

Paul VanOver, March 08, 2007 - 4:22 pm UTC

Using the techniques described in this topic, I have created a nice little utility package in Oracle for sending email messages. I have resolved all the issues I was having, except for one.

Here is a code snippet:

    g_mail_conn := UTL_SMTP.open_connection(pMailHost, 25);
    UTL_SMTP.helo(g_mail_conn, pMailHost);
    UTL_SMTP.mail(g_mail_conn, pFromEmailAddr);

    l_to_list := LoadEmailList('To: ', pToEmailAddr);
    l_cc_list := LoadEmailList('Cc: ', pCCEmailAddr);

 
    UTL_SMTP.open_data(g_mail_conn);
  
    UTL_SMTP.write_data(g_mail_conn, 'Date: ' || to_char(systimestamp, 'dd Mon yy hh24:mi:ss tzh:tzm') || UTL_TCP.CRLF);
    UTL_SMTP.write_data(g_mail_conn, 'From: ' || nvl(pFromEmailAddr,'unknown@unknown.com') || UTL_TCP.CRLF);
    UTL_SMTP.write_data(g_mail_conn, 'Subject: ' || nvl(pSubject,'(NO SUBJECT)') || UTL_TCP.CRLF);


If you will notice I am using systimestamp and I have added the tzh:tzm to the format string and it returns the -5:00 for my time zone quite nicely. I am hoping this resolves all my time zone issues.

When I get messages that are sent from my oracle package, there is only one thing I don't know how to resolve. The Received Date on the message is perfect, but if I modify Microsoft Outlook, and add the Sent column to the email view, the times are wrong on those messages. They are 5 hours off. Is there some other attribute in the header I was suppose to set???

The data looks like this in Outlook:

From                 Subject   Received          Sent
vanoverp@saic.com    test      3/8/07 3:34 PM    3/8/07 10:34 AM


Thanks so much for any guidance you may provide.

Paul
Tom Kyte
March 08, 2007 - 8:38 pm UTC

you'd have to ask "outlook" what they are looking at.

not sure what they expect there.

oops, I did it again.

Paul VanOver, March 08, 2007 - 5:25 pm UTC

I figured it out. I had a mistake in the format in the to_CHAR method.

I changed it to
to_char(systimestamp, 'dd Mon yy hh24:mi:ss tzhtzm')


and life is all good now. YES YES YES>..

Thanks so much for all these awesome examples.

Tomasz G., March 14, 2007 - 6:00 am UTC

Yes but utl_mail is for smtp servers without autentication mode. I have server with autentication, oracle XE and I need to send email with attachements... is it possible?

sure, you just have to encode it yourself.

eg: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1739411218448

the way tyler sent HTML as an attachment in that example

sending attachements

Tomasz G., March 19, 2007 - 8:53 pm UTC

Ok finally I've got it. The secret was in MIME headers and boundaries. Now I can create emails with attachements (all types) where I want.

Thank you for help

Tom:

I have an application that send an email via a trigger after a user creates an order. IN the last month, some emails have not been going through. I check my email table and there is a record but emails were not received.

DO you have an idea what might be causing this and whehter it is realted to 9iR2 patch for timezone thing.

I tested it in SQl*plus and sometimes I received and email and sometimes I do not.

declare
begin
mail_pkg.send(p_sender_email=>'my_email@system.com',
p_from=>null,
p_to=>mail_pkg.array('my_email@system.com'),
p_cc=>mail_pkg.array(),
p_bcc=>mail_pkg.array('my_email@system'),
p_subject => 'ORder Confirm',
p_body => 'test1'||Chr(10)||'test2');
end;

you should never ever send email in a trigger.

http://asktom.oracle.com/Misc/part-ii-seeing-restart.html
http://asktom.oracle.com/Misc/part-iii-why-is-restart-important-to.html

however, if you run that plsql block and it returns without error, and you sometimes do not get the email - the problem is NOT in the database.

look to your email system, your SMTP server. it is broken.

I'd ask the owner of said SMTP server

probably - overloaded or file system full.

send email to smtpout.secureserver.net

Razaul Karim, April 03, 2007 - 12:29 am UTC

Mr. Tom,

I have followed UTL_SMTP accordingly for sending email from Developer 6i Forms. It is working well last 1 year when our smtp server was vmail2.bdcom.com. Presently we are using godaddy mail server (smtpout.secureserver.net). When I am sending a mail from Dev 6i the system is giving following error message.

ORA-29279

I am using the following Code:
create or replace package mail_pkg

end if;
end loop;

end;

end;

Please give me a solution, I will be very grateful to you.

use telnet, telnet to the server and just converse with it.

take oracle out of the loop, you'll see the error lies with your conversation with the smtp server.

debug it - whittle it down, make it small, get the least amount of code humanly possible to reproduce your issue

and the problem may well become self evident.

PL/SQL - Email

Rajesh Shridharan, April 23, 2007 - 5:44 am UTC

Hi Tom,

I am trying to implement Email solution through PL/SQL using Oracle 9i. I want to send the Email to id in yahoo / rediffmail, However I am getting error :

ORA-29279: SMTP permanent error: 553 sorry, that domain isn't in my list of
allowed rcpthosts (#5.7.1)


Can you please explain how can I can implement this?

Regards

Rajesh Shridharan

Tom Kyte
April 23, 2007 - 4:33 pm UTC

see your network people and ask them to add you to the list of domains that are allowed rcpthosts....

nothing to do with the database
everything to do with your smtp server.

smtp server

A reader, May 01, 2007 - 5:08 pm UTC

Tom:

I checked with the email server admin about the email problems from an oracle application (emails not getting sent out or even received by email server) and he suggested to install an smtp server on the box where the database is installed or have the oracle application do queueing for the busy smtp server as it gets backed out sometimes?

1. How do you install/configure an smtp server on a unix box running oracle? can this be done?

2. Does MAIL_PKG in oracle suport queueing. Since we are using a job to schedule the email, is not this queueing since if the job fails (server down) oracle will try to send the job 14 times in 5 minute intervals?

Thanks,
Tom Kyte
May 01, 2007 - 9:04 pm UTC

1) your email server admin would know how to do that - it is just smtp, a simple service.

2) Oracle supports job queueing, you would have a job that tries to send mail and upon failure, would just try again later.

you could use dbms_job
you could use dbms_scheduler
you could use AQ and do it yourself in however you see fit.

java.security.AccessControlException error

Anne, June 04, 2007 - 2:15 pm UTC

I have 2 schema's in a 9.2.0.4 database : bps and mr_proj. Package SendMailJPkg is compiled in bps schema as authid CURRENT_USER. Sending email with attachment works from from bps schema. My problem is when I send email with attachement by running bps.SendMailJPkg from mr_proj schema : I get java.security.AccessControlException error. Ending email without attachment works fine from mr_proj. I am not sure what I am doing wrong...Could you please help.

This are the steps I followed:
1. In bps schema : create public synonym SendMailJPkg for bps.SendMailJPkg;

2. grant execute on SendMailJPkg to mr_proj;

 exec dbms_java.grant_permission( 'MR_PROJ', 'SYS:java.util.PropertyPermission', '*', 'read,write' )

The PL/SQL to grant this is dbms_java.grant_permission( 'BPS', 'SYS:java.io.FilePermission', '/r03/app/oracle/admin/mris/mr_proj/log/abj.req', 'read' )

It is complaining that the permission is not given to BPS. However I do not want BPS to be able to access mr_proj's log dir, that's kind of why I defined the SendMailJPkg as authid CURRENT_USER. 



Appreciate your help Tom.

it'll need it - you eventually call other non-current user bits of Oracle.

the plsql/java called by compiled plsql is compiled/linked with the definer - (eg:

you can create an authid current_user procedure 'p' OWNED BY 'owner', to be run by 'runner'

owner has been granted execute on P2
runner has not

P compiled by OWNER can invoked P2
when P is executed by RUNNER - P will invoked P2 successfully.


It is "SQL" that is invokers rights capable.

Can't send mail using UTL_SMTP

Sukhendu, June 22, 2007 - 6:11 am UTC

Hi Tom,

When I am trying to send a simple mail through pl/sql using oracle 9.1 . It throws the following error:

ORA-04067: not executed, package body "ME.UTL_SMTP" does not exist

What should I have to do to send the mail. Please suggest.

utl_smtp is a sys owned package, sort of like dbms_output, and the rest.

whatever "ME" is is wrong.

                           p_recipient IN VARCHAR2,

I see you have a language other than english set there, are you sure your email body is simple ASCII text (smtp expects that)

that works (the routine), works for me - you can do it all in telnet without Oracle if you want to test and see what you see there.

In 9i I was sucessfully able to send email with attachments. Now my requirement is to save the sent email in the database for audit purpose. Can you please explain options?
Tom Kyte
December 17, 2007 - 3:25 pm UTC

option 1:

a) insert


??? seems rather straightforward, relational databases have tables, insert your stuff into a table.

Just like any other data you have a requirement to keep.

Pat, December 21, 2007 - 3:36 pm UTC

Thanks for your response Tom.
I have a requirement to save as how the email show if we do a save as,I have to save with all the header info.
1)Is there any way we can recieve an email in the database, so that i can save the received email.
or
2)Is there any way we can direct the out of the sent email to save to a table.
Tom Kyte
December 21, 2007 - 4:04 pm UTC

java has lots of support for connecting to email data stores (IMAP, POP) and would give you the ability to "read the mail"

Just like I demonstrated above for sending - you can certainly do the same for reading.

But basically, you'll be writing a program to read email from an email server, format the data, and insert it into the database - not necessary to have the program that does that IN the database, probably doesn't make sense to have it in the database - sounds more like an external program that runs on it's own accord, reading mail, formatting it, inserting it.

Another option would be to use an email server that stored the data in the database in the first place - we have one (collaboration suite) for example.

Pat, December 21, 2007 - 4:27 pm UTC

Thanks Tom you are wonderful.

UTL_SMTP and Shared Server

Emad Kehail, January 05, 2008 - 3:04 am UTC

Hi Tom,

We have been using the package utl.smtp to send email in our database. We have built a package called DEMO_MAIL which uses the UTL_SMTP package. The code has run successfully for more than 3 years without any problem. Lately, we changed our server configuration from Dedicated server to Shared.
End users starts to report problems while our applications try to send emails
the error code was as follows:

ORA-29278: SMTP Transient error: 421 service not available
ORA-06512: at "SYS.UTL_SMTP", line 17
ORA-06512: at "SYS.UTL_SMTP", line 96
ORA-06512: at "SYS.UTL_SMTP", line 138
ORA-06512: at "ORAPROG.DEMO_MAIL", line 240
ORA-06512: at "ORAPROG.DEMO_MAIL", line 118
ORA-06512: at line 118

We have done the following tests:

* When connecting to the server using a didected connection there is no problem.
* When connecting to the server using a shared server the above error occurs and sometimes it works successfully!.

Moreover, when we execute it many times we start to receive the error:

ORA-30678 too many open connections

Despite our code close the session with mail server.

Is there any problem in using UTL_SMTP with Shared Server configuration in Oracle Database??


Thanks.

Tom Kyte
January 07, 2008 - 7:23 am UTC

you may contact support and reference bug 4083461 but....

one easy way to correct this AND have it be faster all around for your end user experience would be....

to use dbms_job to schedule the sending of the email. What I do on asktom is

a) insert the email information into a table (this is instantaneous for the end user)

b) commit my transaction.

Every 5 minutes or so, a job wakes up, queries the email table for unsent mail - sends it.


Sending Email

Rich Bulan, January 07, 2008 - 4:42 pm UTC

Tom,
We've successfully implemented email workflow via the database examples that you've provided. I would love to see some additional examples that utilize some of the advanced features of email.
*How to email messages (and subject lines) in non-ASCII character sets (French Canadian)?
*Examples for how bounce back emails are handled?
*Clear documentation on what really happens when we send emails via these procedures like utl_smtp or utl_mail. The information from documentation could really use some comprehensive examples:
http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/u_smtp.htm#sthref19034

Thanks!
Tom Kyte
January 07, 2008 - 5:35 pm UTC

You'd have to read up on the SMTP protocol itself - OR use the java api's - but that is outside the scope of a database question sort of- you want to learn SMTP.


for bounce backs, you'd have to write an email client that wakes up, reads the inbox, parses the email and figures out what it wants to do (it is just a data problem - think of the inbox you have your bounces go to as if it were a bunch of files, you can use pop or imap to read them - just like we use smtp to send them)

As for "what happens", you want to read the SMTP RFC - we just open a tcp/ip socket to a SMTP server and speak their documented protocol - ctl-f for telnet on this page and you'll see a rather "raw" conversation. There is on magic here, it is all just "smtp speak" - and that protocol is well documented (google it and you'll find a lot of references)

Sending emails from Shared Server

Emad Kehail, January 08, 2008 - 1:27 am UTC

Yes Tom, it seems it is a bug, and according to Metalink note 358776.1, patch 9.2.0.8 should solve it.

I will test it and see about it.

It is also solved in Oracle 10g R2. However, we are currently discussing upgrading to Oracle 10g R2 or Oracle 11g R1. I hope the patch solve our problem till we upgrade.

Thanks for your cooperation

Tom Kyte
January 08, 2008 - 7:33 am UTC

I would still use dbms_job

it'll make email "transactional", so if the surrounding transaction rolls back - so does the email. If you commit, the email will be sent. The end user transaction will go from taking measurable seconds to instantaneous.

No way we should send email in real time, background it regardless.

Sending emails from Shared Server

Emad Kehail, January 10, 2008 - 2:07 am UTC

We have applied patch 9.0.2.8 and everything is fine now.
Regarding your point about transactional emails. As always you were right here. I have talked to our developers. They are using Oracle Forms and they are sending emails either from POST-INSERT, POST-UPDATE, POST-DELETE or database triggers.
This could lead to problems if the form has executed the trigger and sent the email, then the database might rollback the transaction if a constraint is violated for example or anything else happened prevented the database from *committing* the transaction.

I do believe now we need to follow your idea about how we send emails.

Many thanks for your valuable hints.

Tom:

1. Is installing java api the only choice to send an email with an attachment in oracle 9i database?

2. Can the attachemnt work with any column type meaning if I have document_table with a blob i can select the file from that row. What about if i have a varchar2(2000) column would that be attached as I need to create a file first?

thanks,
Tom Kyte
March 24, 2008 - 11:16 am UTC

you have utl_smtp in 9i

http://docs.oracle.com/docs/cd/B10501_01/appdev.920/a96612/u_smtp.htm#1000695

and smtp is just a protocol, you would encode the attachments (using base64 or uuencode) and create a "correct and proper SMTP 'document'"

It requires more code than using something out of the box, but it can definitely be done. Tyler Muth did it with "html mail" here:

http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1739411218448

he did not have to encode the html attachment, as it was just ascii text, but the concept is the same

email

A reader, March 24, 2008 - 2:17 pm UTC

Tom:

It seems the java option is easier as you have all the code written for it.

With utl_smtp do I need to add more coding/testing or
the procedure html_email( ) will handle everything?

2. also, can attachements be any column type like "CLOB", "BLOB", varchar2(4000), etc.

Is there anything special that needs to be done for each type.

Thanks,


Tom Kyte
March 24, 2008 - 7:31 pm UTC

html_email will send.....

html, nothing more, nothing less. It was an example of what you would have to do...

2) using javamail - it won't matter, it will encode them, doing it YOURSELF, you would have to write different interfaces/implementations for each type of course.

A reader, March 24, 2008 - 2:29 pm UTC

Tom:

Another small question on utl_smtp. I already use that for plain text emails "no attachments". Does this mean that I already have the Jave code requried or do i still need to download those two files (mail.jar and activation.jar).

is there a way to check if those two file are already compiledi nto the database.

thanks,
Tom Kyte
March 24, 2008 - 7:32 pm UTC

read that html email answer again.

see what tyler did there with the "attachment" stuff.

that is what you would have to code, AFTER encoding documents using base64/uuencode

if base64/uuencode mean nothing to you - please use the javamail api :)

if that means something to you and you understand the attachments and how SMTP wants them and all - you'll be able to make the decision "build versus buy" here (write it or use the java mail API)

A reader, March 24, 2008 - 3:22 pm UTC

Tom:

Per your instructions i downloaded "jaf-1_1_1.zip" and "javamail-1_4_1.zip" from the Sun website.

I extracted each file contents and did find mail.jar and activation.jar.

Then I got lost on your instructions. You say to

1. Use winzip to extract the contents of mail.jar into c:\temp\mail dierctory. There is no files inside this exectable file??

Did you mean something else?

2. Use winzip to create a new archive c:\temp\mail8i.zip.

Do you mean a new archive of the original files in "javamail-1_4_1.zip".

3. Put the contents of c:\temp\mail\*.8 including subdiretories into this new archive.

I thought you want us to extract the mail,jar only first. What are we zipping here exactly?

Thanks,

Tom Kyte
March 25, 2008 - 6:32 am UTC

a jar file is a zip file - just unzip it.

jar file

A reader, March 25, 2008 - 6:10 pm UTC

Tom:

I tried this many times and it does not work. These are executable files.

I ran winzip and i opened javamail-1_4_1.zip. This zip file has two files "mail.jar" and "mailapi.jar".

These are defined as "Executable jar file". I selected the files and clicked "extract" but nothing is done. I do not think these have any files inside them.

So what do you do now. do you unjar and rejar those for compilation into the oracle database.
Tom Kyte
March 26, 2008 - 8:50 am UTC

you extract the jars.

please re-read the page....

.... quote ....
After you have downloaded these two sets of files ? you will need to extract
mail.jar from the JavaMail APIdownload and activation.jar from the JAF
download.
This is all you will need from this ? feel free to read through the
documentation, there is a lot of functionality in there we are not using, we
are just using the 'send an email' part of the API. The API includes functions
for receiving mail as well from IMAP, POP, and other sources.
.......

we need the jars from the zips

email

A reader, March 26, 2008 - 10:18 am UTC

Tom:

I did that. My question is regarding what you say next to unjar/rejar those. There is nothing to unzip in those executables.
----------------------------------------------------------
We will need to load the mail.jar and activation.jar into the database using loadjava but
before we can do that we must repackage them. These jar files are compressed in a format
that is not understood by the database byte code interpreter. You need to 'unjar' and
'rejar' them without compression or use a tool such as WinZip to 'rejar' them into a zip
file. What I did on Windows 2000 was:

1. Used WinZip to extract the contents of mail.jar into my c:\temp\mail directory
2. Used WinZip to create a new archive c:\temp\mail8i.zip
3. Put the contents of c:\temp\mail\*.* including subdirectories into this new archive
-------------------------------------------------------
Tom Kyte

go ahead, open them with winzip, see what you see. a jar is just a zip.


a jar is a zip

no, you can use loadjava over a network - you just need to have it actually be installed.

you use dbms_java to load a jar file that is on the server already.



dbms_java is a store package, it runs in the server, it has absolutely ZERO access to your filesystem, it only has access to the server.

Thanks.

In the meantime, can you give us a hint.

do we have to compile activation9i.zip before mail9i.zip or you think it is related to the zip file itself, or the iBM aix.
Tom Kyte
April 10, 2008 - 4:06 pm UTC

I don't have access to my 9i system, nor will I, until next week at the earliest. I'm on the road and all I brought with me was 10g and 11g.

If you follow the directions step by step - it should work. If you have a java person around, they can inspect the zips and verify everything that is needed is there.

A reader, April 10, 2008 - 4:30 pm UTC

Tom:

OK, thank you for your response. I will look forward for your 9i check next week.

In the meantime, I wil double check the zip files creation and see if i can find a java person to verify it.

A reader, April 10, 2008 - 5:00 pm UTC

Tom:

BTW, would 10g or 11g solve the attachement issue. I noticed you mention UTL_MAIL above that seems to send attachements.

just wondering when we upgrade to 10g or 11g, i still need the javamail api or oracle has other apis already installed.
Tom Kyte
April 10, 2008 - 8:34 pm UTC

there are api's to send mail with attachments in subsequent releases - yes, you can read the documentation on otn.oracle.com

but if i need a code for http server so can anybody help me up with that....

as we are using http server

sorry, but that doesn't make any sense whatsoever.

you are using http server.

so what, you are apparently using a database too.

A reader, May 05, 2008 - 10:18 am UTC

Tom:

This what we get on the tar for the java errors. I think this is wrong answer.
Do not your procedures in old book "expert one on one" page 1237 also apply for 9i and 10g. is there new procedures for 9i in the new 9i/10g book.


--------------------------------------------------------
Java mail was supported in 8i, as per Note 120994.1 . Not truly supported for 9i / 10g.
We recommend using UTL_SMTP (9i) and UTL_MAIL (10g), as they are built-in packages to accomdate email functionality from within the database.

Beware: JDK 1.3 is installed in 9i and cannot be upgraded.

Tom Kyte
May 05, 2008 - 2:36 pm UTC

that would not be accurate, anything that is good for java in the jdk loaded in the database should be supported - it is a JVM - a JVM is a JVM. You would have to make sure the java api's you are loading were built for the jdk in the database.

utl_mail doesn't support large attachments, it is not a general purpose replacement.

utl_smtp doesn't do attachments unless you do 100% of the work (ie: encode document, output document bounaries - it - utl_smtp - does NOT DO attachments)

A reader, May 05, 2008 - 3:42 pm UTC

i am suprised they would have such a false note on metalink.

How can i do this? check the api agaisnt the jdk versions? this could be the issue.

Problems with permissions

A. Olsen, July 31, 2008 - 11:34 am UTC

Hi Tom

I am using Oracle 10g Database - OS is AIX5L
I have written the functions mentioned above for sending e-mails with attachments using JavaMail API - thanks for the info - they seem to work just fine.

However, I seem to have a problem granting permanent Java IO permission to files.

Connected as sysdba, I have executed the following regarding a user called s_dba:

SQL> select user from dual;

USER
------------------------------
SYS


SQL> exec dbms_java.grant_permission('S_DBA','java.util.PropertyPermission','*','read,write');

PL/SQL-procedure er udført.

SQL> exec dbms_java.grant_permission('S_DBA','java.net.SocketPermission','*','connect, resolve');

PL/SQL-procedure er udført.

SQL> exec dbms_java.grant_permission('S_DBA','java.io.FilePermission','\tmp\*','read, write');

PL/SQL-procedure er udført.

(Please forgive the Danish output from SQLPLUS :)

I am trying to attach files, that already exist in /tmp and give read/write access to all, f.x.:

-rwxrwxrwx   1 root   system  21704 30 jul 15:07 pic1.jpg
-rw-rw-rw-   1 abc    usr       325 31 jul 08:02 t1.txt

When I send an email, using JavaMail, I receive an error message like the following, every time I try to attach a file:

java.security.AccessControlException: the Permission (java.io.FilePermission /tmp/t1.txt read) has not been granted to S_DBA. The PL/SQL to grant this is dbms_java.grant_permission( 'S_DBA', 'SYS:java.io.FilePermission', '/tmp/t1.txt', 'read' )

To accomplish the task, I execute the command for each file that has to be attached, but how come I cannot grant the permission to "/tmp/*" so it would affect all accessible files?

Thank you

A. Olsen

UPS :-)

A. Olsen, July 31, 2008 - 11:56 am UTC

I seem to have copied a wrong line from SQLPLUS, the one with the obvious error...
But no worries - I have also run the comand with the right slashes:
exec dbms_java.grant_permission('S_DBA','java.io.FilePermission','/tmp/*','read, write');
and:
exec dbms_java.grant_permission('S_DBA','SYS:java.io.FilePermission','/tmp/*','read, write');
- without any effect on the result.

The Oracle documentation states:
To denote all files within a directory, provide the * symbol, as follows:
/private/oracle/*

Invalid email addresss...Culprit?

Reader, September 25, 2008 - 1:39 pm UTC

Tom,
Can this error "ORA-29278: SMTP transient error: 421 Service not available" occur due to invalid email addresses?
I personally doubt it...Please pour in your ideas?

Tom Kyte
September 25, 2008 - 4:00 pm UTC

if email address validation was on, you would get another error - not a "sorry, smtp just isn't working right now" typically.


like something in the 500 range. 421 means "sorry, not working at all right now"

sam, December 12, 2008 - 8:42 am UTC

Tom:

In your example below (for 9i R2 database), is it possible to have "p_subject" data from a CLOB column in a table. Can you show a simple example how you would do it. Would there be a limit if 32000 characters size sent in the subject.


tkyte@TKYTE816> begin
2 mail_pkg.send
3 ( p_sender_email => 'tkyte@us.oracle.com',
4 p_from => 'Oracle Database Account <tkyte@us.oracle.com>',
5 p_to => mail_pkg.array( 'tkyte@us.oracle.com',
'thomas.kyte@oracle.com' ),
6 p_cc => mail_pkg.array( 'tkyte@oracle.com' ),
7 p_bcc => mail_pkg.array( 'utility@aria.us.oracle.com' ),
8 p_subject => 'This is a subject',
9 p_body => 'Hello Tom, this is the mail you need' );
10 end;
11 /

Tom Kyte
December 12, 2008 - 8:52 am UTC

sure, it could be a clob

You would just loop over it using dbms_lob.substr and write bits of it at a time.


line 69:

 68      utl_smtp.write_data( g_mail_conn, '' || g_crlf );
 69      utl_smtp.write_data(g_mail_conn, p_body );
 70      utl_smtp.close_data(g_mail_conn );
 71      utl_smtp.quit(g_mail_conn);



would have to become a loop, something similar to (not debugged or compiled, just consider this psuedo code):
l_len := dbms_lob.getlength(p_body);
l_offset := 1;
while( l_offset <= l_len )
loop
   utl_smtp.write_data( g_mail_conn, dbms_lob.substr(p_body,32000,l_offset) );
   l_offset := l_offset+32000;
end loop;

email

sam, December 12, 2008 - 9:54 am UTC

Tom:

Thank you, i will try that.
another small question

1. Would this pl/sql package work for sending the CLOB as an attachment. It claims it does but i do not see anything in "mail" procedure to select an attachment from a table.

http://searchoracle.techtarget.com/searchOracle/downloads/SendingAttachmentsViaUtl_Smtp.txt

2. My CLOB size is about 6000 - 8000 bytes. The easiest way seems to be UTL_MAIL.SEND_ATTACH_VARCHAR2 even though it has 32K limit.

However, this does not seem available in oracle 9i R2. is this correct?

Tom Kyte
December 12, 2008 - 10:48 am UTC

1) you would have to evaluate it - I didn't write it, you can investigate it.

I wouldn't think it would select from a table, rather I think YOU would select from YOUR table - get a clob and pass it as a parameter.

2) or just put it into the body, it is tiny.

see:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1739411218448
for an approach

email

sam, December 12, 2008 - 11:22 am UTC

tom:

you mean using "html_Email" instead of adding the loop
to "send_mail".

This is a CLOB that has an XML file (might be valid or not). WOuld sending thins in HTML be appropriate more than plain text.

l_len := dbms_lob.getlength(p_body);
l_offset := 1;
while( l_offset <= l_len )
loop
utl_smtp.write_data( g_mail_conn, dbms_lob.substr(p_body,32000,l_offset) );
l_offset := l_offset+32000;
end loop;


Tom Kyte
December 12, 2008 - 12:50 pm UTC

I mean to read the link to see how you can send an attachment.

I don't care if you send it in html, xml, sgml, rtf, whatever - you wanted to send an attachement - that was an example of "how to send an attachment"

email attachment

sam, December 12, 2008 - 6:02 pm UTC

Tom:

This pure PL/SQL procedure works in 9i in sending an attachment. The only thing its send BLOB attachment

1. Do I need to send my CLOB data (xml file) as a CLOB or i can still send it attached as a BLOB using this? would there be any difference.

2. If I have to change it to attach CLOB instead of BLOBs can you assist because I had a bunch of errors.

smk - i already showed you how to send a clob via the Tyler Muth "html email" example.


Please - slow down, understand what you are looking at, don't try to 'hack it together from bits and bytes', design what you need and implement it.



email

sam, December 13, 2008 - 11:57 am UTC

Tom:

I will try that. But as you know this is NOT sending the CLOB as an attachment. I believe it is in the body -- which does not mean it wont work.

In your opinion, when do you decide to send CLOB in an attachment versus body as html or plain text. Which do you think is more practical and useful from a user prespective?

The CLOB is just an xml file that shows product test results. The emails are sent from customer to vendor to show whether the product failed or passed the test. I had to create the column as CLOB because the program that creates this string does not create WELL-FORMED XML.

Internet Explorer seems to open the attachment fine as XML when i set the MIME to xml. However the Firefox generated an parse error and could not open it.


Tom Kyte
December 29, 2008 - 8:01 am UTC

umm, then think about it - it is quite simple.

Just loop over the clob and write 32k of it at a time. done.

why you would mail an XML file in the body however is beyond me. Seems you would want to a) attach it, b) with an appropriate mime type so the person you send it to could actually save it as it was originally intended and do stuff with it.


when you put the xml into the body of the email - you sort of "made it not be xml anymore)

email

A reader, December 15, 2008 - 1:10 pm UTC

Tom:

I tried the html_email procedure for the XML file in CLOB.

It is unreadable. The attachment opened it up nicely in XML format in Internet Explorer.

Is there a way to display it in tree XML hierarchy with HTML email .


Tom Kyte
December 29, 2008 - 10:46 am UTC

you don't say what you did - you did change the mime type and all right.


And no, there is NO WAY using html email to display a XML 'tree', you need software that ingests XML, and prints onto a screen.


And obviously, it is NOT unreadable. "The attachment opened it up nicely in XML format in Internet Explorer.", that sort of proves "mission 100% accomplished".

Look - you need something that ingests XML and displays it the way you want.

That is not SMTP (that is just email)
That is not your email client (they do not typically do that, just like they do not display - say - a word document but rely on word to do that)

You send the XML as an attachment, with the right mime type and assuming the recipient has installed software that can render XML, double clicking on it in their xml client would run the application that can display it.

Can you resolve this puzzle. I create a clone of your MAIL_PKG and did not change anything and I get this error. The call with original MAIl_PKG runs fine

you are sending mail_pkg.array to a package mail_pkg_bk.

The package mail_pkg_bk undoubtedly wants mail_pkg_bk.array's, the type is was defined with

Please disregard the last message. The call was passing paraemters pointing to the old package.

that is not ambiguous, your smtp server requires you to log in, I don't have that code in there, you'll need to add it.

Charset Problem in sending emails

vikas, March 18, 2009 - 10:08 am UTC

Hi Tom,

When i send plain text emails using UTL_SMTP. I get special char in the email text. For eg £(GBP) appears like ú, euro appears like Ç but $ appear correctly.

Pl help me with this.

Thanks,

Vikas

email is by default 7 bit ascii. Your gbp and euro are in fact "special characters"

the $ is not, it is in 7 bit ascii.

<quote>
Note that the original SMTP protocol communicates using 7-bit ASCII. Using UTL_SMTP, all text data (in other words, those in VARCHAR2) will be converted to US7ASCII before it is sent over the wire to the server. Some implementations of SMTP servers that support SMTP extension 8BITMIME [RFC1652] support full 8-bit communication between client and server. The body of the DATA command may be transferred in full 8 bits, but the rest of the SMTP command and response should be in 7 bits. When the target SMTP server supports 8BITMIME extension, users of multibyte databases may convert their non-US7ASCII, multibyte VARCHAR2 data to RAW and use the WRITE_RAW_DATA subprogram to send multibyte data using 8-bit MIME encoding.

CLOB usage instead of BLOB

Suresh, May 20, 2009 - 3:44 am UTC

Great. This is excellent solution for sending eMails with attachemnt, though using 10g, used this instead of Utl_eMail. This combines with DBMS_XMLQuery,storing xml into CLOB and sending as "xls" attachment. Also placed the "CLOBData Source code" which may replace the class "BLOBDataSouce".

static class CLOBDataSource implements DataSource {
private CLOB data;
private String type;

CLOBDataSource(CLOB data, String type) {
this.type = type;
this.data = data;
}

public InputStream getInputStream() throws IOException {
try {
if (data == null) {
throw new IOException("No data.");
}

return data.getAsciiStream();
} catch (SQLException e) {
throw new IOException(
"Cannot get Ascii data input stream from CLOB.");
}
}

public OutputStream getOutputStream() throws IOException {
throw new IOException("Cannot do this.");
}

public String getContentType() {
return type;
}

public String getName() {
return "CLOBDataSource";
}

Tom:

I have an oracle application that sends an email after it saves an order via a job.

The email goes to a main person and CC list of 5 people and one bcc (me).

The main person and I received it. Some CC list people claim they do not get it.

They are all valid emails.

1. Is it possible that this could happen - some not receive it?

2. Does the email log means basically that the job was sheduled to be sent to email server (not actuall sent to email server)?

3. Is thre a way to verify that recepient
