That is what we do. The problem that came up is that I have this set to 32 work volumes. The size of the input was such that each sortwork had to be larger than the largest sized volume that we have (3390-3s). We currently have 60 3390-3 volumes in out temporary work pool. There is a debate now as to whether it would be better to increase the number of work volumes in the pool and make the sortwork number >32, or to leave the number of volumes the same, but make them "larger", say 3390-9. We are currently on a 2105 (Shark) without PAV. Our requested upgrade to a newer DASD array has been denied. We've been told that if we need more space, we will be given an older EMC array which is already on the floor. In any case PAV does not look to be an option. So we are concerned about performance. Management doesn't directly care because "the mainframe is going away" so no moneys will be spent unless they are forced. But the mainframe performance is still critical because the mainframe usage is still increasing. So if performance suffers, for __any__ reason, then it is just more proof that the mainframe is junk. Yes, I'm still P.O.'ed at this attitude. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
