Dave,
I had a similar problem with appl environments which were not defined in
WLM. Since then I'm sensitive to this set of problems.
No, I'm not sure it's TCPIP alone. What I see is that PING times go up
when capping starts and RMF3 shows big (processor)delays for TCPIP.

30% of what? What is 100%?
Velocity for an exvel goal. And I even found the rule in the
Planning WLM book:
Certain types of work, when overachieving their goals, potentially will
have
their resources
The highest exvel I've used so far is 30 for the online workload (IMS,
DB2). If I want limit donations from that online workload so I should
define a higher exvel than 30?
yes. That's how my odd exvel31 came about.
I don't mind if higher prio work is assigned less resources under capping,
but

Actually, at the time of capping (and tcpip NOT running), do you have
service
classes with a PI of less than 3? Less than 1?
There are some SCs with a PI 3. Very rare are PIs 1, and then just for
a minute.
Unfortunately I don't have the data available anymore from last week. For
another PMR at IBM I had to change the RMF intervall from 1h to 15min and
the higher amount of data shortens the available period in RMF3. It's time
to adjust the dataset sizes.. But this week is expected to get again
Jim,
we don't have DB2 in SYSSTC, just the IRLMs. Application Server run in an
own SC with a high goal, but still lower than SYSSTC.

The normal delay is under 10%. I can't think of another address space
than TCPIP
1. Check all things TCP for where they run.
There is also a subsystem type TCP, do you have this defined? Or is
there
anything in service class SYSOTHER?
All TCP related STCs are running with SYSSTC, no address spaces in
SYSOTHER.
I don't have any subsystem type TCP defined in WLM, do I

There is no such thing by default. It could be created with a fair

A fair amount of work?? Under subsystem
Tried already to shift TCPIP into SYSTEM, but is not allowed. WLM can not
starve STCs defined in SYSSTC. Why does WLM not cut the processor for the
batch jobs which are defined DISCRETIONARY?

Ignorant questions:
Does TCPIP handle the Ping itself, so no other adress space is involved?
What is the delay % under normal (good) response situations?

The normal delay is under 10%. I can't think of another address space
than TCPIP
to handle the PING. Probably OMPROUTE, but it's also defined as SYSSTC and
is
delayed for a much higher percentage than at normal times.

Jim, while you can assign STCs to SC SYSSTC there is no definition
in WLM and no way to set the CPU critical flag.

Well, of course I can do that but they always warn to define unachievable
SCs.
Anyway, I'll give it a try.
