Ken,
Do all the following as a way to minimize MTTR (Mean Time To Recovery) for
a variety of scenarios and, by the way, they happen to use a lot of disk:
;-)
1. Mirror your online and archived redo logs to multiple drives
2. Put backup copies of drive A' datafiles on drive B (or C) and vice
versa. Do this on multiple drives as well to guard against multi-disk
failure.
3. Do frequent exports to support object-level recovery.
All that chews up disk and, actually, comes in pretty handy when you need
them.

Hi,
I was wondering how DBAs are coping with these new large disks that are
available....you can purchase 36gb, 72gb, etc. You can fit a whole database
on one of these. But with all the performance and redundancy
considerations, you wouldn't....so what do you do with the free space? Or
how do you tell your bean counter that out of that 72gb you are only going
to use 10gb so you need a couple of these?
Rgds, Ken Heng
