RMAN-20301
        operation not supported; Recovery Appliance administrator should use the DBMS_RA.DELETE_DB API instead
        
        
        Cause
        The UNREGISTER command was attempted for a database that was using the Recovery Appliance.
        Action
        The Recovery Appliance administrator can use the DBMS_RA.DELETE_DB API to release storage and unregister the database. Note that using the DELETE_DB API will delete the database and all of its backups from the Oracle Recovery Appliance, not just UNREGISTER it from the catalog as RMAN does.
