Hello,
We are in the process of migrating from TMON to Omegamon.
I'm t
TMON MVS screen option 1.1.8 which displayed the CPC's

I'm trying to find the value of the defined capacity in MSU values (real
numbers and not just YES or NO), and the value of "Current MSU" which is the
real time current MSU consumption of

My understanding is that when a system is using dynamic LPAR allocation, a
maximum defined capacity for a given LPAR can be set, something less than
the CEC capacity. Anyone know where that's defined (what control block)?
That is, given three LPARs on a 1000 MSU box, each might be allo

That statement is not correct:

Ok, that is better. The term "softcapped" could apply to either LPAR Defined

Let's try to clear this up. LPAR Defined Capacity works with or without IRD as
expected. LPAR Defined Capacity also works well when used with LPAR Group

Hi Al,
Back from holidays, I was reading the requests about IRD and DC/GCL and saw you
answered them.
My understanding is however, that IRD Weight management stops, "when an LPAR is
softcapped", both by the Defined Capacity and by the Group Capacity Limit.
This is probably e
IRD weight management and Defined Capacity work fine.
The problem comes with IRD and LPAR Group Capacity Limits (introduced in z/OS
1.8). The problem is when an LPAR Group is capped IRD stops adjusting weights.
This is rather unfortunate as this is the time when a customer would most want

I'm trying to understand how to set up Defined Capacity for an LPAR.
Unfortunately HMC help is not helpful and software manuals do not
provide details about the settings.
My goal is to set up Defined Capacity for one LPAR. No groups.
