Remember that many large oracle servers use most of a tape and at times many tapes for a single database backup. When this is the case there is little need for collocation because there will be little if any tape contention for restores. Also when you recover from the primary pool you are less likely to need to recovery many servers at once so even when possible tape contention exists it isn't an issue.
Before I get blasted, I know you can never say you won't have a problem but many times the the cost and drawbacks outway the benifits to collocating database data or large file data. Or you could backup your data to a noncollocated storage pool. You could then run a seperate server process that moves the data to a collocated storage pool each morning or something like that.

I have 3494 tape library with 4 tape drives and I am using the collocating feature. the DBA uses 4 channels on his script to do the backup The problem is when I turn the collocating on , only one channel will do the backup and the others will wait and when I turn it of all the 4 channels will backup at the same time. Can anyone tell my if there is a way to backup the DB with 4 channels and with collocating on? Regards, Abdulaziz Almuammar --------------------------------- Do you Yahoo!? New and Improved Yahoo!
