Manmohan, Connect to the Rman repository via sqlplus as your Rman user. You do *not* have to have your old 9i database up and running. Run the following script to remove (unregister) the database within the Rman Catalog: To remove a database from an Rman catalog, you must use a stored package provided by Oracle. Declare L_dbkey number; L_dbid number; begin select db_key,dbid into l_dbkey,l_dbid; from rc_database where name = 'dbname'; dbms_rcvcat.unregisterdatabase(l_dbkey,l_dbid); End; Good Luck!

I upgraded a database from 9i to 10g and switched to 10g repository for RMAN backup. I want to delete the older backup from 9i repository. I still have the saved copies of 9i version controlfiles.
