Folks- While I would agree that with all the memory made available to LPARs, you rarely need the locals to back Real pages (of course, prove me wrong with some ginormous sort). But you must also consider what else The locals are used for: that is, SVCDUMPS. If you need to dump a 128GB (virtual) address space, you better Have enough locals to cover that. So while 3 Mod 3s may cover most of the environment, I've seen many shops Start with 10 Mod 3s for Locals, with additional volumes on those systems with large virtual tasks. I also recommend Having a few spare volumes with formatted page datasets on them, just in case... Happy New Year! zNorman

Two days ago it was too hot. ;) 31 degrees around Pretoria, now 17-28 degrees with possible rain. ;-) http://www.weathersa.co.za/web/index.php (I really hope there is rain on 31 Dec/1 Jan, because I hate fireworks.) >>I think you should post your actual problem you're trying to solve. >not really trying to solve any problem, just making sure things are still set >correctly. I saw your reply to Ron Hawkins about PREVENTING problems. I agree with you that having extra page datasets could help a lot. I think you should monitor all your DB2 LPARS and watch out for any aux shortages. Then you can enlarge your page dataset(s) as needed. What tools are you using to monitor your online storage?
