PTF, changes in Parmlib, WLM, etc? Just don't get mad at me please, but in such cases I would ask around just to be sure. [1] >Today we had the same problem and it was again solved by a reactivate of the >current WLM policy. I find it weird. Is that only on that one and only LPAR, but never on the others? What about the other LPARs, are they running at full speed without delays, etc? If you means 'reactivate', do you mean - re-activate across SysPlex or just on the problem LPAR? Are the other LPARs using the same RG setup? >This is z/OS 1.13. >Anyone an idea where to look further? I wish I have something, but perhaps you could see if there are any delays at all. I will ask my favourite IBMer about this. We got nearly every month problems about 100% CPU, GRS lockout, delays, etc, but usually we can resolve it, or it 'goes away'. Groete / Greetings Elardus Engelbrecht [1] - Dec 2014 - Our CPU went 100% and everything grinded at a halt - up to the whole CEC - After tracing and detective work - even after the programmers swear high and low they did *not* *changed* *anything* - we found the culprit - Some second-hand *$$hole wrote a 'Christmas animation' (15 screen updates) for every user who logs on. Now many users got p*ssed off about that animation and log off and logon back - guess - that just made it worse... ;-D ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
