I suppose just how much redundancy makes you sleep well is up to you. But,
one additional bit of info to keep in mind is that the backup info also gets
stored in the control files, and rman can use those too if no catalog
database is available. Making a copy of a control file after the backup
We have both 8i and 9i instances, but 'eventually' plan to migrate everything to 9i.
I'm looking at using RMAN for our backup and recovery. We have many instances but
essentially 2 types.
1. Production instances that have both OLAP and OLTP. These must be in archive log
mode.
2. We have
I do not think you need 2 Rman catalogs.
Build a small database just for Rman. After the daily backup finished bring
it down and do os level backup of all the environment for this small backup.
You can then easily restore it in case of disk problems.
Remember: A backup is good only when you can
i must have misread the docs. i thought it was either catalog or control file. didnt

Brian - Hopefully Robert will have a chance to respond to your question, but
if I might make some suggestions, I think your recovery time has two
components:
1. If the backup files are not on disk, the time to locate the tape, load
the files.
2. RMAN recovery time. I think you will just have
Is this all live OLTP type data, or might some of the data be made

deal then look into incrementals). I can't begin to guess at the time

You can uncatalog any archivelogs you have removed without using rman. This
will accomplish what you wish. But for the future, try to an rman
archivelog backup with the delete option. This put the archivelogs in a
backupset and then deletes them. Rman know right where
