Can anyone tell me where the SRM CPU Management Control Table
(CCT) layout is documented?
In my copy of "MVS Data Areas", I hit a dead end at the RMCT,
which contains the RMCTCCT field pointing to the CCT. I can't find a
layout for the CCT itself.
I want to include, in a class I'm teaching, a sample Rexx exec
that fetches the CCVUTILP field from this control block and displays
the current CPU utilization, to illustrate the use of the Rexx STORAGE
function to chase through MVS control blocks.
I've used this technique in a variety of languages, and I don't
even remember where I first found the recipe for it. The sequence is
CVT::CVTOPCTP ==>> RMCT
RMCT::RMCTCCT ==>> CCT
CCT + offset x'66' = CCVUTILP
I don't really want to include examples that I can't document
properly. Some folks don't really like being told "Well, that's just
part of the Great Oral Tradition (TM)".
