I had changed my shared pool size from 608M to 1G using the below command.

alter system set shared_pool_size=1G scope=spfile;

After restarting the oracle service, I am not able to connect to oracle instance. I am getting below error :

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Can someone please suggest how do I now rollback the shared pool size changes,as oracle instance could not be connected.

Thanks,
Sachin

ORA-00838: Specified value of MEMORY_TARGET is too small, needs to be at least 1088M

Please suggest how do I fix this, as I am not able to connect to oracle instance.?

Connect with SYSDBA privileges, and generate a pfile from your spfile. Make whatever edits you want, and re-generate the spfile from you edited pfile. For example,

Code: [Select all] [Show/ hide]

sqlplus / as sysdba
create pfile='c:\tmp\initornage.ora' from spfile;
host notepad c:\tmp\initornsage.ora
create spfile from pfile='c:\tmp\initornage.ora';
startup force

I have been able to resolve the issue by increasing the memory_target as recommended in below link :

I am disturbed by the fact that the guy that wrote that article thought you needed to actually start the database from the pfile before you could create an spfile from it, thus necessitating yet another restart of the instance. It is not.

Code: [Select all] [Show/ hide]

SQL> create pfile from spfile;

File created.

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> create spfile from pfile;

File created.

SQL> startup
ORACLE instance started.
