Yeah, same with me when I worked in Manufacturing. A little different in Brokerage..Especially, with "big bucks" flowing thru networks... or Pharm, when NDA are being done and you can't IPL or make changes because of the lost of possible revenue.

That worked very well, as at 6:00 PM they shut down all of the onlines and did backups. To shut down and IPL just added about 15 minutes. One big advantage to IPLing every week is that the operators know how to do it. They deal with it every week. When you IPL once a quarter or less, the operators forget. We were manufacturing, which isn't near as critical to keep the system up 24/7, although occasionally when the factory was really busy, we would skip the IPL because they were running the factory on the weekend also. I think IPLing more regularly keeps some things less fragmented, although I doubt if that causes any real problems. Business need, as several have said, should dictate how often you IPL. Certainly, changing releases of z/OS requires an IPL, and major maintenance should be done with an IPL.
