We do use it extensively on our development environment to clean things up after the evening compliance scanning and backups that are memory intensive. It runs at a random minute in the 4am hour to avoid running it on all at once.
There are some thing that it doesn't get along with it: DB2, GPFS (Spectrum Scale), and TSAMP. Clustering things don't like the "pause" so any of the Linux-HA stuff would fall in that category. But works great for WAS servers and things like that. -----Original Message----- From: Linux on 390 Port <[email protected]> On Behalf Of Rob van der Heij Sent: Tuesday, May 15, 2018 1:44 AM To: [email protected] Subject: Re: [LINUX-390] zLinux tools and toys site for Developers Ray, Indeed, as Mark points out "cmmflush" is not part of the s390-tools or any other package in your distribution that I am aware of. I did it back then as part of my performance research, and it happened to be useful as-is for some Linux on z/VM installations. It's pretty much the recipe from the blog post written out in a bash script. Google points me to https://zvmperf.wordpress.com/2015/02/11/user-experience-with-cmmflush/ My original blog post hasn't changed since 2012, so if the recipe does not work for you, finding a fresh copy may not fix that. If you can explain the scenario, we may be able to help you sort it out.
