I never said that this is silly. Pop Quiz: Q. What did I say is silly. A. "forcing overflow of PLPA when you have a dedicated volume is just plain silly" I also said it would be pigheaded. > > > Have you ever considered that the measurements are not based on > dataset level I/O counts? > Yes.

I monitor and increase it as required. I have been setting up 100 CYL PLPA Volumes since EMC first said to me "can you use this leftover space?" back in 1996. > > I'll worry about what to feed the unicorn when I see one. Shane and I have seen and fed the unicorn... Remember all those threads that talked about paging due to DUMPSRV. Well if you take a good close look on some systems is not the page faults to the locals that are causing all of the problems. More often then not I have found "bursts" of PLPA and Common page-ins correlate with system lockups. Burst of Page-ins from locals tend to only be affecting a few ASID and so far I haven't found Local Page-ins causing the lock-ups that coincide with Common/PLPA Page-ins. > > While I am discussing how to configure it on a real system with a real > load. > You are trying to say that I have never worked on a real system? I didn't expect insults from you. I've never worked in a Lab or a Factory, so just what were all those Banks and Telephone companies that employed me doing with those mainframes?
