The usual starting places... Performing Query SEssion during the activity gives you a real-time look; and performing 'netstat' on AIX allows you to gauge delay source. Performing Query Node ... Format=Detailed right after the backup will yield wait time values which help show where delays were occurring. Or you can look at the accounting records. You don't indicate the nature of the backup. Whereas there were ANE records in the TSM server Activity Log, this should not have been an API- based TDP type of backup, thus suggesting that either Oracle was shut down or that the backup was "wild", and so standard issues affecting throughput (client factors, including file region locking; TSM storage pool speed, etc.). See the TSM Performance Tuning Guide for many things to review. ADSM QuickFacts summarizes numerous elements which can affect backup performance. Richard Sims
