First, let's distinguish between CMM-1 and CMM-2/CMMA. It is the latter that
is being dropped by IBM. It will remain in the distribution versions in which

So you should probably measure the two before deciding on which one you
want to keep. CMM-1 has very positive results, cmma not so positive.

At the risk of bringing on the wrath of the performance gods, I just

Well, we think so. It's been very stable so far.
It's available, with support, etc.

I was wondering how you turn on each of the offerings.
I have looked in several manuals and they talk about and compare the CMM
offerings, but they were not specific on implementation.
We load the CMM module via
/etc/sysconfig/kernel
MODULES_LOADED_ON_BOOT="vmcp cmm"

General rant aside, I think that's the point
Wow..I don't really know how this discussion got so far off-base.
For several years now, there has been a lot of discussion in the z/VM
community about the need to have a place to collect the "wisdom of the
elders", i.e. the knowledge and experience of those of us who have been

Good question. You've turned on CMM1 on Linux, but as I understand it,
there must also be a *collaborative* piece enabled on z/VM.

We tried CMM-1 a month or two ago on a single guest. Without VMRM,
there's nothing for it to talk to, so it does nothing. (It works by
having VMRM send it notices to decrease working set size.)
With it enabled on one guest, on a machine slightly memory constrained,
it drove the memory utilization
This presentation might be of some interest to those looking
at the CMM-1 and CMM2/CMMA options:

The RecentChanges page has an RSS feed button on it.
All of our RHEL4 guests are pre-update-7 and unlikely to be upgraded any
time soon. I think I've seen this doc before. Thanks though.

Mike, CMM does require a collaborative piece. Or one can tune the
system manually with CMM commands, but that gets boring. VMRM should
have been enough, but it has very poor feed back mechanisms, and has no
clue about what is happening inside Linux. It is thus severely limited,
has lots of repor

Was CPFMTXA run against them to initialize them?
Mark Po
Yes. And I tried both formatting at the mini disk level and not
formatting the mini disks.
Possible I made a mistake with CPFMTXA?
