Re: REGION=0M leads to CPU through the roof

I don't see paging as the culprit. To page out 1.6 GB of memory and then reference it to bring it back in still indicates an application problem. Especially with a total elapsed time of only 12 minutes. I suspect that the application built a table. Spent wasted time searching it. Sent from

Charles, YES I AGREE, storage nowadays can do a lot of paging, and support a CEC easily burning 11 minutes of CPU time paging. DPR rates of 100,000/sec are a walk in the park for current IBM, EMC or HDs controllers, and probably higher on a boxes that can do >2,000,000 cache hits a second. Of

Re: Questions about IPL with package IODF

A couple of assumptions. OP has only one CEC with multiple LPARs, right? IODF 'package' just means the (linear) VSAM cluster IODFxx, right? First off, I have to say that this is an unusual way to manage IODFs. We have three CECs in the enterprise, but we use (multiple copies of) a *single* IODF

Re: Questions about IPL with package IODF

I copy the production IODF(s) to the outside system(s). There is a hardware token in the HSA that must match the token in the IODF. The OP received a message stating the token does not match. This is a result of the installation creating a separate IODF for usage with certain LPARs. You

Re: DFHSM QUESTION

Lizette, The reason why I think that it is a problem because after I run the AUDIT using NOFIX the output shows the dsn (*err 40). I do not see this for other LPARS. My understanding is that if any errors appear a clean up is needed to be initiated. In this case only ERR 40 appears.

I would also be interested in what you have coded on the IODF statements in your LOADxx members and what are the names of the IDOF(s)? I suspect you will have to do a software only activate on the international LPARs (and test as well if you want), then a Hardware/software activate on the
