RMAN backup of a duplicate database

I look after two hosts, one with a prod database and the other runs dev & test. Now, dev and test are refreshed with a copy of prod every so often. This has been done by o/s level file copies and control file creation.

RMAN online backups have just been set up for all instances. At the moment, each host has its own catalogue database because of the duplicate dbid problem. I plan to have one catalogue per host after doing refreshes with the RMAN duplicate command.

Consider what happens when the recovery catalogue on prod's machine is used to duplicate prod to, say, dev generating a new dbid for dev.

What happens when I go to do an RMAN backup using the dev machine's catalogue? The dbid will change every time I do the refresh and this is what RMAN uses to identify the database.

What actions do I need to take on the dev machine's catalogue? Received on Wed Sep 11 2002 - 06:36:48 CDT
