RAC orapw file
A Reader, January   07, 2010 - 4:21 pm UTC
 
 
In a RAC environment, there are separate orapwDB files for each Instance, so does it mean that these orapwDB passwords can be dffferent from one instance to another ?
I thought passwords are tied to database, not instances. 
 
RAC password

Hi Tom,
I ran into a similar issue twice. The situation is like this - I forgot the SYS password for our dev RAC nevironment. So I logged in to one of the nodes and connected using sqlplus / as sysdba. I did an alter user SYS identifed BY....Later, when I tried to login to that specific node from another machine, this new passsord was working. But when I tried to login using the SCAN, the new password was not working. I gave up trying because of other priorities. The next day, the new password was working for the individual node as well as SCAN. What might explain this?

you don't ever log in as sys anyway, you can forget it.
why are you even using sys???????

Hi,
I logged in using sys as sysdba.

do not do that, use your OWN credentials.
why did you post this before?
sys%ORA11GR2> connect sys/manager
ERROR:
ORA-28009: connection as SYS should be as SYSDBA or SYSOPER
you NEVER need to use sys, never.  
either use your own credentials to become sysdba, or use OS authentication and connect / as sysdba using an OS account that is privileged to do that.

Hi Tom,
You asked me "why did you post this before? 
sys%ORA11GR2> connect sys/manager
ERROR:
ORA-28009: connection as SYS should be as SYSDBA or SYSOPER"
But I did not post anything like that.

you said you were logging in as sys with a password?

Hi,
I said I logged in using sys as sysdba. Anyway, let us leave that aside. My doubt was, is there a lag- a delay between nodes in a RAC as far password updates are concerned. The doubt is for the logins using the password file.

there is a single password file, no latency.
sqlplus / as sysdba
DOES NOT USE THE PASSWORD FILE.
the only time the password file would be used is over the network.  connect user/ps@remote as sysdba
If you used / as sysdba, no password is ever needed.  You could
connect santa/clause as sysdba 
it would work as well as
connect boo/hoo as sysdba
connect foo/bar as sysdba
connect anything/you_want as sysdba
the user/password are not relevant.  It uses OS authentication.

only if you purposely decided to NOT share it.  As that article itself states.  It is normal to share the password file, to have one.  If you decided to have many - it would be up to you to synchronize them, yes.
and again, it would *NEVER* affect:
connect sys/foobar as sysdba
because we DO NOT use a passwordfile for that.  Given that you wrote:
So I logged in to one of the nodes and connected using sqlplus / as sysdba. I 
did an alter user SYS identifed BY....Later, when I tried to login to that specific node from 
another machine, this new passsord was working.
you said you were logging in "/ as sysdba" - the password file doesn't come into play at all.  It is all about OS authentication.
I can only respond to what I see written.   
 
 
Alter user system

I changes the system password with alter user (by mistake) 2 minutes later I changed it with his old password.
After I had a problem with a archivelog synchronisation. We had to copy the filw with passwords.
Is it because I changed the system password? Event if I rechanged it again 2 minutes later?

"archive log synchronization" ?  Are you talking about DataGuard ?
Basically anything that requires SYSDBA access to a *remote* database will be using the password in the orapwd file.

Yes but it's about a rac cluster 
December  01, 2017 - 2:50 am UTC 
 
For a RAC environment, I would have a single password file shared across the instances.

Ok but you didn't answer my question 
 
SQLPLUS connection string anomalies

 Hi Tom / Team, Thank you guys for the and knowledge sharing and continued help provided to the entire Oracle community towards their queries and  issues. I too have a few, to start with..
Can you please explain and help me understand why sqlplus/oracle is behaving differently when logged in -
1) Using SQLPLUS;
[oracle@olx8e admin]$ sqlplus
SQL*Plus: Release 12.2.0.1.0 Production on Thu Jul 16 05:33:24 2020
Copyright (c) 1982, 2016, Oracle.  All rights reserved.
Enter user-name: system as sysdba
Enter password: ********
Connected to:
Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production
2) SQLPLUS connection string (with sysdba) as -
[oracle@olx8e admin]$ sqlplus system/********@odbe as sysdba
SQL*Plus: Release 12.2.0.1.0 Production on Thu Jul 16 05:31:54 2020
Copyright (c) 1982, 2016, Oracle.  All rights reserved.
ERROR:
ORA-01017: invalid username/password; logon denied
3) Connection string (without sysdba), as -
[oracle@olx8e admin]$ sqlplus system/********@odbe
SQL*Plus: Release 12.2.0.1.0 Production on Thu Jul 16 05:30:31 2020

Last Successful login time: Thu Jul 16 2020 05:24:08 -04:00
Connected to:

My ask above besides, whats causing connections in above scenarios to succeed or fail and what i can do to make them consistent so in any of above scenarios the connection to DB is a success? 
Things I have tried:
----------------------------------------------------
Recreated the password file with orapwd utility
Altered password using alter user command
am using same password for both above
tnsping gives o.k, both on local / remote server.
4) Lastly, how should one connect to an Idle Database Instance (with just Oracle software installed and no DB created) remotely using TNS connect string?

(1) All local connections are implicitly SYS when connecting as sysdba, eg
C:\>sqlplus blah as sysdba
SQL*Plus: Release 19.0.0.0.0 - Production on Fri Jul 17 14:26:12 2020
Version 19.5.0.0.0

SQL> sho user
USER is "SYS"
(2) Is SYSTEM granted SYSDBA? Normally it isn't - you use SYS
(3) As above. SYSTEM is a normal user.
(4) orapwd sets the SYS user coming in across the network.  And then you do:
connect sys/pass@my_tns as sysdba
