>Why do you need to consolidate extents when most data sets can have 123 per >volume? Unless you really mean contiguous space.
PDS's, PDSE, unexpected growth. We had one group of datasets for a customer or two that was allocated in tracks, only a couple hundred cylinders in total. Suddenly, the business turned on a switch and boom! We are also finding one storage group that if we don't defrag, we SB37 everynight on 1000's of jobs. We are changing allocations to handle this, but the business is growing faster than we can keep up. And, not all of our (ancient) applications can handle EXTEND datasets. So, it's defrag or die! STOPx & friends were considered too expensive. And, BRIGHTSTOR isn't good/smart enough. Sad, but true. As I said, extent consolidation is the only reason for defrag. If you don't need it, don't defrag. If you do, do! - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
