Re: Idea: Using SCRT to report on Linux usage; maybe a way to reduce the entry level cost for Linux on Z?

IBM already has a sub-capacity accounting tool for Linux on Z and LinuxONE: the IBM License Metric Tool (ILMT). ILMT is already facilitating sub-capacity licensing of IBM software products on Linux on Z and LinuxONE. Details here:

Re: RHEL 6.9 servers getting Unknown program exception: 0028 SMP

Rick, Terri, Greg, and others, apologies I should have given out the PTF numbers and a little more background on my earlier append. APAR VM65396 PTF UM34851 is the one that introduced the prog check problem. We discovered the problem February 26th, and marked VM65396 in error on March 1st with

Re: RHEL 6.9 servers getting Unknown program exception: 0028 SMP

Thanks Bill. I was a little suspicious of VM65414. However, VM65396 has been on these LPARs since March (before I knew about the later PTF) and we did not see any problems until Linux got patched this week. I guess I will have to scramble to get another VM IPL. 8-\ Rick Barlow On Thu, Apr 12,

VM65414 is PE'd... can't find anything on it now. It looks like PTF UM34768 is the latest out to fix this, and it came out April 4? I have VM65396 on, but have different Redhat levels than Rick mentioned. Thanks, Terri Glowaniak Mainframe Systems Engineer terri.glowan...@regions.com

Bill, Has the dust settled now on the z/VM Spectre fixes? We put on VM65396 as well on a couple of systems then halted that until further fixes arrive. On 4/12/2018 7:26 AM, Bill Bitner wrote: Rick, if you have VM65396 on, but not VM65414, that would be my guess. VM65414 corrected a problem

Rick, if you have VM65396 on, but not VM65414, that would be my guess. VM65414 corrected a problem introduced by VM65396 where a guest could erroneously be given a program check 28. ___ Bill Bitner - z/VM
