Hello I have done a upgrade from oracle 9.2.0.1 to 9.2.0.5. Now, I need drop an user and I have the error:

ora-00604 error produced a level 1 recursive SQL
ora-00942 table or view doen´t exist

I have re-run the script catalog.sql and catproc.sql but I have the same error.
Can anybody help me?
Thanks a lotˇ
