Charles I think the RCTIMGWU field is what you are looking for, in short
it's defined as
Image defined MSU's - as the softcap is changed that value is updated,
I'm not 100% sure that's what your asking, if not sorry.
Mark's Rexx performs some calculations to report on used MSU's on a
rolling 4hr average and the unused MSU for the 4hr average

@Carmen, thanks, that is a huge help. RCTLACS is documented as
Long-term average CPU service used by this logical partition, in millions of
service units per hour. If this value is above the partition’s defined
capacity, the partition will be capped. It is calculated using the physical CPU
adjustment factor (RCTPCPUA) so it may not match other measures of service
which are based on the logical CPU adjustment factor. It is available if the
hardware supports LPAR cluster
I am assuming I can get to the RCT (possibly by IPLINFO) and as an added bonus,
the field is GUPI!
So yeah, there is half the answer. So the next question is, where do I find "the
partition's defined capacity" (in MSUs/hour)?

Subject: Re: Is there a field that would reflect LPAR soft-capping?
we used part of Mark Zelden's IPLINFO Rexx on MSU usage, the field we
use is
RCTLACS
I'd think you would need the defined MSU's (RCTIMGWU) also and compare
the fields?
Check Marks IPLINFO, I think that would have everything you'd need.
of course there are other tools from other vendors but I think if you
want to build your own I'd be using the some fields Mark uses.
just my 2 cents

I am thinking about coding an STC that would "do something" if LPAR
soft-capping kicked in. Is there a field somewhere in z/OS that gives the
MSU capacity of the LPAR *and that would change to reflect the effect of
soft-capping*?
This is for internal use, so I would be willing to bear the risks of a
non-GUPI field.
Thanks,
