I've read the CP COMMAND manual and the PERFORMANCE manual regarding the
SET SHARE command and how it works.
Would someone care to comment on how you have used them for your z/VSE
production and guest machines?
What would suggest for TCPIP/RSCS/VTAM SET SHARE values?
Thanks in advance.

z9 BC with z/VM 5.2
For years the production VSE and DB/2 machines have used
SHARE ABSOLUTE 85%
in the directory. Most of the time, they get best response, but
a CPU heavy in a test VSE guest can still hog the real machine.

We use absolute shares for VSE machines with limithard during the day and
remove the limit from production at night

You are right - it is not.
We don't run test guests on production LPARs.
Actually, we don't run test LPARs on production z boxes.

Hi Jim,
We run one production VSE guest, runs IDMS/DC (no CICS) all the time.
Batch happens throughout the day, much of it user driven, so day is
usually busier for batch than night.
That guest gets absolute share 50% and LIMITSOFT of 80%.
We have a VSE development guest that gets absolute

We have sufficient enough resources so set share isn't a big deal, however,
I do have production set at set share relative 150 and the test systems as

When they are competing, the production
