It seems that you have misunderstood the doc (URL) you cited. And, you cited the z/TPF WMQ InfoCenter.
The entire application resides in (virtual) storage, including the MQCONN (and other) function calls, and including the parameters that the calls pass to/from the qmgr.
The message data that the program puts/gets resides in storage as well, along with the qmgr code and the o/s.

This can't be done on the old production server on which client has had issues...and because of that they are proposing the new prod server.
anyways.. its logical. And I tried on newly built server.
When Qmgr is not Running
| Code: |
$ vmstat
System Configuration: lcpu=64 mem=256512MB
kthr memory page faults cpu
----- ----------- ------------------------ ------------ -----------
r b avm fre re pi po fr sr cy in sy cs us sy id wa
1 1 3347648 62286264 0 0 0 0 0 0 0 195 219 0 0 99 0

I can see a small difference in avm and fre.
And this snap of memory taken when NO APPLICATION is connected the the qmgr because its a newly built server and no appl. is connected to it yet.
where :
avm
Active virtual pages applicable to the specified page size.
fre
Size of the free list for the specified page size.
Page
Indicates the relevant page faults and paging activity for the specified page size. The page related columns re, pi, po, fr, sr, cy, fi, and fo are also applicable to this report.
