Jim,
There's not enough information yet. Are you running CICS with response
time goals? Are they being met? If you are using velocity goals only,
are those goals being met both before and after the queue buildup?
Input! Input!

We run CICS TS & ADABAS and saw some performance issues with CICS
transactions in z/OS V1R7 although not very bad. When we brought up z/OS
V1R8 we are seeing high level of delays in CICS transactions when they are
going to "redispatch" queue. Talking to IBM lab folks they are telling us
it is not a z/OS V1R8 problem but maybe a CICS performance problem. But
then the CICS people say the transactions are not being dispatched quick
enough off the redispatch queue. I think this has been shuffled over to
the WLM folks.
Like to know if anyone else is encountering CICS performance problems
where it seems the CPU is running 100%, transactions start queueing up,
repsonse gets slow, CPU drops down to 50-60%, redispatch queue gets bigger
and then all them transactions come out at once and FLY through the system.
Is this happening to you or has it happened lately.
thanks Jim
