It depends on your CPU speed and characteristics of TSO usage. If your
users run lots of long transactions like searches, CLISTs, foreground
things, they could suffer. Most TSO activity (in my experience) is of
the short variety, so as you see below I'm not shy about making 1st
period imp=1, but for just 500 service units. We also try to get some
things through in period 2 with a pretty aggressive goal. Works OK
here, but probably not for everyone.
You might ask your users what they're trying to do when they hang.

Subject: WLM and TSO
I am no performance expert and I am basically mostly using Cheryl Watson
quickstart (or whatever it is called). We are only using one service
class
for TSO users. For the most part it works fine but during batch window
we
have times when the operators let a bunch of stuff run in high priority
batch service class. During those times, TSO users tend to sit and
hang.
Of course, the operators bump up their own priority so they don't have a
problem. I am looking for suggestions as to how to setup the service
class
for TSO users to avoid having them hang during these situations.
Here is my service class for TSO:
Base goal:
CPU Critical flag: NO
# Duration Imp Goal description
- --------- - ----------------------------------------
1 800 2 80% complete within 00:00:00.300
2 4 Execution velocity of 40
Here is my service class for PRDBATHI (which I am assuming is causing
the
problem):
Base goal:
CPU Critical flag: NO
# Duration Imp Goal description
- --------- - ----------------------------------------
1 3 Execution velocity of 40
Any suggestions would be greatly appreciated.
Thanks,
Aimee
