Carmen,
Do you have any usermods that move any of the LE runtime programs from SCEERUN
to SCEELPA? I tried this once, and with 30 programs moved over, I lost 1M in
private region size. I do load them into lpa, but I do it via a SET PROG of a
member that does LPA ADD.

Can you share any information about "why"? They don't like to hear where
they are not implementing best practices?
HC is expected not to change anything; it informs.

The boundary between PVT/CSA and ECSA/EPVT is a 1-M boundary.
A tiny change in nucleus, LPA, CSA allocation, SQA allocation can result
in reduction of PVT size

Jerry,
I wouldnt move it, just write a usermod to copy it to NUCLEUS, and update your
NUCLSTxx member.Let the CICS guy tell you when it changes, and you need to
re-apply your usermod.
We incidentally dont install DFHHPSVC. Not sure why, I did ask the CICS guy
about it.
Here is an old
Same here - usermods for IMS and CICS.
Our usermod list has been pretty stable since z/OS V2R1 - only added one.

something changed with the nucleus, but doesn't seem necessary anymore. :)
