RE: RMAN catalog question

So one thing that I just noticed while looking into this. The RMAN catalog schema(tables/procedures/etc) seems to get created based on the version of the target that executed the "create catalog" command, and not the version of the database that is hosting the catalog.

I checked this by comparing the schemas that were created by different versions of oracle. If it was dependent on the version of oracle that hosted the catalogs, they would all be the same. Ours differ by the version of oracle that was used when executing the "create catalog" command.

Thanks

RMAN Compatibility Matrix [ID 73431.1] provides a little more details. RMAN executeable <= target database (when backup 9i database, use 9i RMAN) Catalog schema >= RMAN executeable Catalog database >=10.2.0.3 (note 1)

Based on the information, I would create the RMAN database and catalog using the latest and greatest release to ensure compatibilty.
