1. Go to the database you wish to unregister and get its DBID:
system@HERML> select dbid,name from v$database;
DBID NAME
—————– ——————————
2082566940 HERML
2. Connect to the recovery catalog-owning schema and determine the DB_KEY of the database in the recovery catalog:
rman10@RMAN10P> select db_key,dbid,name from rc_database
2 where dbid = 2082566940;
DB_KEY DBID NAME
—————– —————– ——————————
555419843 2082566940 HERML
3. Use the dbms_rcvcat.unregisterdatabase procedure to unregister the database from the recovery catalog (this procedure takes the DB_KEY and the DB_ID that we just found as parameters)
— The syntax for the procedure is:
— dbms_rcvcat.unregisterdatabase(db_key,db_id);
In recovery catalog schema –
execute dbms.rcvcat.unregisterdatabase(555419843,2082566940);
