ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance

How to fix the ORA-32004 error?

Cause: ORA-32004 causes because one or more obsolete parameters were specified in the SPFILE. These depreciated parameters are still in use by spfile.

Action: See alert log for a list of parameters that are obsolete or deprecated. Remove it from the SPFILE.

You must check alert log to see the names of the parameters that are obsolete.

select name from v$obsolete_parameter where isspecified='TRUE';

                                           OR

select p.name,p.value
from v$parameter p, v$spparameter s
where s.name=p.name
and p.isdeprecated='TRUE'
and s.isspecified='TRUE';

Once found, you must remove it from the spfile or pfile.  You can use alter system command to remove it from spfile.
