Do they shut down the Oracle instances before they do the backups? I had an SA once who wouldn't and it consistently produced corrupt control files. Had to do a recovery every Monday morning. I finally educated him.

Hi all,

I got the following from our Unix admin. Looks like control files for some database on many boxes got changed when being backed up on tape. (I suppose the backup on tape happened during mid-night) Does anybody know what the reason is, and why this only happened to control files? Thank you. -- Janet

Following are Oracle warnings during the nightly tape backup:
