Hi David There are always a trade-offs in life. I have worked with RMAN since 8.0.4 and I think this is one of the greatest features Oracle have enhanced the database with. In the battle regarding multible catalogs vs. one catalog for databases my experience with customers is that one catalog per database is the best for the following reasons : 1) Upgrade of the catalog does not influence other databases 2) It is possible to backup (export) a single database 3) You don't get performance problems since the catalog will not be gigantic 4) It is easy to play with the catalog when doing advanced recovery tests. 5) Selecting with Sql*plus (or other tools) are simpler 6) Security administration is possible. 7) Moving of a single database repository is easy 8) Deleting databases from a repository is easy 9) Patching of repositories takes less consideration 10) The downside is more administration :-( /peter David Wagoner wrote: >I've heard of another suggestion- to create a separate RMAN schema for each >Oracle version that connects to the repository DB. >I'd be interested to hear your opinions on that option and if anyone has >experience using this approach. > > >Best regards, > >David B.
