Regions and jobname report
Within a trace interval, a thread can be assigned to multiple CICS® systems but it can only be assigned to one CICS at any one time.
Depending on the number of CICS systems
connected to DBCTL, the regions and jobname report can show:
- One region with only one jobname.
- One region with multiple jobnames.
- Multiple regions with multiple jobnames where some regions have the same jobname, and some have multiple jobnames.
- Multiple regions with only one jobname.
Any monitor report for a region is a summary for all connected CICS systems that a thread has served during the trace interval. For example, the elapsed time of schedule end to first call means the sum of this elapsed time for all CICS systems that a thread has been assigned to during the trace interval.
Depending on the workload of a CICS system, a trace interval may be a relatively short period of time, and thread switching between depending regions may not occur very often. However, the more the workload fluctuates, the more frequently threads are likely to be assigned among connected CICS systems.
