ADMIN MSGUSER VMRMADMN
NOTIFY MEMORY LNX* S10* RH5*
This example will apply to z/VM user IDs whose names begin with LNX, S10 or RH5.
3. Edit the PROFILE EXEC on AUTOLOG1 so that VMRMSVM is auto-logged at IPL time. Logon to
AUTOLOG1.
4. Before pressing Enter at the VM READ prompt, type acc (noprof so that the PROFILE
EXEC is not run. Then add
LOGON AUTOLOG1

How to observe that CMM1 is working
The answer to the question: “How do I know CMM1 is working?” is not entirely obvious.
From the z/VM perspective you should see resident pages and total pages for the
CMM1-managed virtual machines drop when the system comes under constraint. For
Performance Toolkit, this would be seen in UPAGE report (FCX113).
The ballooning driver releases the pages it has pinned by using Diagnose x'10'. You can see
the diagnose 10 counts in PRIVOP report (FCX104).
Some other items of interest may be users in page wait, see USTAT (FCX114).
From within Linux, you can check the size of the pool of pages put out of play using the
following commands:
# cat /proc/sys/vm/cmm_pages
# cat /proc/sys/vm/cmm_timed_pages
