   Root cause for the issue:
just got the error after DB upgrade to 11204 and it throws the error.even when we unregistered the db ,it did not give any result.
just looked the database and found the PSU on $ORACLE_HOME applied while the database open.

Solution:
just  do the clean DB restart and it will resolve issue.
