Q

Changing the Database Identifier (DBID)

Oracle expert Brian Peasland explains why you never have to change the DBID.

When do we need to change database identifier (DBID)?
Never. In all my years as an Oracle DBA, I have never once had to change the DBID. The only reason I can think of to change the DBID has to do with RMAN and a Recovery Catalog. But even then, I'd just blow away that DBID in the Recovery Catalog and reregister the db with the RC and take a good backup.
