RE: Rman ... what do YOU need

I'm currently struggling with the MML & Veritas NetBackup. What I'd like is cohesive definition and examples showing use of the views (v$backup_sync_io and v$backup_async_io) that are there to supposedly let me know if the tape is streaming, and to compare throughput from the point of view of RMAN with theoretical throughput for both the tape devices and the disk devices.

I'm using asynchronous IO, slaved IO processes and multiple channels to tape in an attempt to get a data warehouse backed up in a reasonable time. This takes a great deal of large pool memory, which I'd like to override at times
(e.g. when running a job that should give a small amount of output, it'd be
nice to be able to override the large pool use, sort of like forcing a dedicated server with sqlnet.ora from the client when connecting to an MTS listener.)

Some indication of the balancing act between backup times and recovery times would also be good.

So I guess the ideas boil down to this:

o how to tell if you're getting the most from your RMAN config o how to plan resources for optimal use by RMAN o balancing time-to-backup with time-to-recovery

Hope this helps...
Steve
