See your utilities manual. Oracle provides a utility to rename the
database in the control file to support manually duplicating a database
or just changing the db name due to IT standards.

Hi Dennis,
Thanks for your input. Unfortunately, the process failed. When I tried
recreating the controlfile to include the missing datafiles, it
complained of the file headers having incorrect database name. This is
because the first time the database was renamed (say from ORCL01 to
ORCL02) and opened with a resetlogs.
Anyway, the apps team is not considering doing the entire copy again.
Thanks for all your replies.
Cheers,
Kanwar
