Re: Lots and lots of redo logs

!! Please do not post Off Topic to this List !!

Hi

Thanks. That's a very good point. I agree that ARCHIVELOG mode will be needed.

However, I still have this big disk just for redo logs, so I'm tempted to fill it anyway. This will be a "sort of" supplementary backup in case the archive disk (+ database disks) crash before the backup. Of course it is only "sort of" because, as you say, a runaway process will cycle the logs if it generates lots of redo.

However, this seems better use of the disk space than just having a few log groups and leaving the rest of the array empty and unused. Unless there are any other implications?

Thanks
- Bill.
