MODULE SECTION LINE PROCEDURE START
NAME NAME NUMBER NAME LOC

.SVC SVC 056 RESOURCE MANAGER/ENQUEUE
.SVC SVC 048 RESOURCE MANAGER/DEQUEUE

Strobe is pointing to ENQUEUE and DEQUEUE location. This location is consuming 15000 CPU sec per Sec. We need to tune this region. Could you please let us know how to start. let me know if you have view on this.

what is the difference between a CPU second and a second?

I would have thought after the TCPIP thread you would have stayed avoided using such statistics.

Is this an application program issuing MVS ENQ's and DEQ's? SVC's should never be used in CICS as they cause an Operating System Interrupt. In other words, CICS will STOP until the SVC has completed. Not a good thing.... icon_eek.gif

Hello,

It sounds like there are more significant issues that merely CPU usage.

Someone Qualified needs to review the transactions' design and processing flow.

If the transaction volumes increase, this may become completely unsupportable . . .
