If i refresh my DB with duplicate command from prod to dev, does the DBID changes or the same DBID of DEV prior to refresh will be retained.
Does rman cleanup works depending on DBID or ORACLE_SID?
If DBID then how rman cleans-up old db backups with old DBID's(Considering the DBID's change when i use duplicate command to refresh) for the same database(SID)
Please suggest. I see old database backups on disk even after retention and delete obsolete.
so want to know how this works.
Command to refresh:
duplicate target database to <DEV_SID>;
I do use catalog
Thanks,
Tarun.
