You Asked

I have a oracle 12c installation.

Following commands were executed as SYS user.

ALTER SYSTEM SET MEMORY_MAX_TARGET=20G SCOPE=SPFILE;
ALTER SYSTEM SET MEMORY_TARGET = 20G SCOPE = SPFILE;
ALTER SYSTEM SET PGA_AGGREGATE_LIMIT = 15G SCOPE = SPFILE;
ALTER SYSTEM SET PGA_AGGREGATE_TARGET = 20G SCOPE = SPFILE;

Database was shutdown.

Database was restarted.

We end up with an error

ORA-00838: Specified value of MEMORY_TARGET is too small, needs to be at least 22912M

Now either we cannot stop the database nor correct the MEMEORY_TARGET. We end up with

ERROR at line 1:
ORA-01034: ORACLE not available
Process ID: 0
Session ID: 0 Serial number: 0

How do we recover from this?

Thanks!

and we said...

If your instance is down, you can still adjust parameters by temporarily making a static pfile, eg

C:\oracle\>sqlplus / as sysdba

SQL*Plus: Release 12.2.0.1.0 Production on Fri Apr 7 13:57:50 2017

Copyright (c) 1982, 2016, Oracle.  All rights reserved.

Connected to an idle instance.


SQL> create pfile = 'c:\temp\init.ora' from spfile;

File created.



Then you edit the file and use that to start, ie

startup pfile=c:\temp\init.ora

and then, once your database is open

create spfile from pfile=c:\temp\init.ora

Maybe the answer is updated because when I try to do that now I get those after startup pfile=c:\oraclexe\init.ora, i can create the file but after that, i get this again ORA-00838: Specified value of MEMORY_TARGET is too small, needs to be at least 2048M
ORA-01078: failure in processing system parameters

Yes, but the point here was that you can then *edit* the pfile you created to correct any of the errors you have. Then once your instance is started, you can create an spfile out of that pfile.

Thank you it worked for me.

Glad this helped.

Parvaz, November 23, 2019 - 12:15 pm UTC

Thank you for the solution! It works!

i had to add quote around the file location while creating pfile from the spfile.

ie: create spfile from pfile='c:\temp\init.ora'

thanks, works so good, but. In linux must includ all spfile route and the (') character.

example:

create spfile='/u01/app/oracle/product/version/dbs/spfilename.ora' from pfile='/u01/app/oracle/product/version/dbs/init.ora'

Thank it work

Naeem Zayid, January 19, 2021 - 8:10 pm UTC

Thank it work with me, the point is to edit the init,ora file while DB is down, then I edit the file
..
xe.__data_transfer_cache_size=0
xe.__db_cache_size=0
xe.__inmemory_ext_roarea=0
xe.__inmemory_ext_rwarea=0
xe.__java_pool_size=0
xe.__large_pool_size=0
.
.

.
.*.memory_target=714572800
,

than I run

startup pfile=c:\temp\init.ora

Thank a lot
