Rich,

Sorry, but I don't have any 9.2 win32 dbs to test against.
Perhaps an upgrade to 10g R1 with 10.1.0.4 and 10.1.0.4 patch 10 might be in
order?
Perhaps 10.1.0.5 + the CPUJan2006 patch instead?

Here is a snipped from an alert log from yesterday.
Yes, the online redo logs are being switched here far too frequently.
No, the online redo logs are sized just fine - there's just too much redo
being generated.
That is another matter.
