Hi Folks,

We're planning to implement RMAN as part of our B&R solution and by extenstion also as part of our DR solution. I've been trying to locate information on how best to configure RMAN across our organisation.

For example it's advised you place catalog on separate server to production server. So server A might house catalog for server B and vice versa. But in a DR scenario where both servers could be destroyed there are I 'suspect' potential implementations on overall MTTR depending on configuration. Is it then perhaps better to locate all catalogs on a dedicated server which ideally would be replicated somehow to eliminate it as a singal point of failure.

Also we have a requirment to be able to potentially recover data as far back as 7 years. These are currently comprised of monthly backups taken out of regular cycle and archived off site. I'm thinking it might be an idea to set up a two catalogs, one for regular monthly cycle and another to record these monthly archives as the maintenace of the catalog might be cumbersome trying to ensure the montlhy archive data records do not get accidentally deleted.

I've had a trawl across the Web courtesy of Google but did not find any papers which appear to deal with these type of issues. The RMAN User's Guide and Reference does not appear to address them either. Your feedback/comments or references to papers would be much appeciated!.
