Home -> Community -> Mailing Lists -> Oracle-L -> RE: Backing up RMAN catalog database
I think it is telling you to use rman without a recovery catalog database to backup the recovery catalog database. The control file for the recovery catalog database will contain the recovery information. Just make sure you backup the control file as part of the backup process (,which is something you should be doing anyway).
Unless you are making use of the recovery catalog database to store scripts then in my opinion there is very little reason to use a recovery catalog with rman. Rman is capable of recovering the database using just the control file and if you lose the control file rman is capable or recovering it first and then recovering the database using a backup control file.

Subject: RE: Backing up RMAN catalog database
Thank you for the link. In it is says "When backing up the recovery
catalog database, you can use RMAN to make the backups", does that mean
to use the rman executable on the catalog database server and write to a
tape on the master mml server? (I guess preferrably to a separate tape
pool than the other backups).
