You can monitor the activity of the CICS® DB2® TCBs using the CICS dispatcher statistics. For more information, see the CICS Performance Guide.
For example, data in the dispatcher statistics section provides the accumulated time for each of the CICS TCBs. The field Accum/TCB is the total processor time used by the corresponding TCB. For more information about the CICS Dispatcher statistics, see the CICS Performance Guide.
You can obtain the total processor time used by the CICS address space from RMF™ Monitor II reports. This time is usually greater than the sum of all CICS task TCBs.
The difference between the processor time reported by RMF and the sum of CICS TCBs in the CICS dispatcher statistics report is the processor time consumed by all the other subtask TCBs. The subtasks are used for:
These are global performance reports and can help you determine how much of your processor time is being used by CICS.
