First of all, Oracle7 requires you to have at least two redo log groups
with one log member each. I recommend you have as many groups as you
need so that the Archiver can keep up with the Logwriter during heavy
loads and that you have two or more log members per group. Oracle
doesn't know whether or not you're hardware mirroring. If you use
Oracle's log group/member mirroring, you eliminate a single point of
failure should the current redo group or a needs-to-be-archived redo
group becomes corrupted.
