Re: New Subscriber's first question.

I would like to thank all of the responders for all their suggestions as they were very helpful. Removing the xstore from the vm 630 solved the problem; paging dropped to near zero and aux storage usage has dropped to 1% from 96%. We are now using the z13 which has solved my cpu utilization

New Subscriber's first question.

I am a systems programmer at Primerica Life Insurance. We have been running SLES linux under VM for nine years. We only have four production VMs on one lpar using a single IFL. We will be installing a Z13 in Jan 2016 which has required me to upgrade all SLES 10.3 VMs to SLES 11.4 and VM from 540

I believe CMMA was withdrawn, and function completely removed in SLES 11. On 12/18/2015 10:12 AM, Davis, Jim [PRI-1PP] wrote: I am a systems programmer at Primerica Life Insurance. We have been running SLES linux under VM for nine years. We only have four production VMs on one lpar using a

I'm sure cmm.ko is what has been called CMM-1. CMMA has been called CMM-2. >From a post in 2009 by Christian Borntraeger makes me assume CMM-2 lite is still there: You also have to distinguish CMM-2 full (SLES10) and CMM-2 lite. We were not able to bring the full CMM-2 version upstream, but

Re: New Subscriber's first question.

Hi Jim, welcome to the mailing list. z/VM 6.3 had many changes to memory management, and it will use more paging space. For one, it will write pages out "early", meaning before it has to actually free up a page. As part of that, XSTORE is no longer recommended and I'd suggest the next time you
