MVS TCB Summary workspace
The TCB Summary workspace compares the CICS® and non-CICS use of the TCBs in your system.
If your z/OS® system is running
slowly, this can be caused by heavy use of a non-CICS resource.
The predefined z/OS TCB
Summary workspace contains the following views:
- Address Space Memory Allocation bar chart provides a comparison
between the CICS and non-CICS
TCB both above and below the 16 MB line.
- Address Space CPU Utilization pie chart compares the CPU usage
of CICS TCBs with non-CICS
TCBs.
- MVS™ Task Control Block Summary
table view shows the name, address space CPU time, address space SRB
time of each TCB. It includes the amount of CPU time and SRB time
since reset. The remainder of the table allows you to compare CICS and non-CICS TCB usage.
- MVS TCB Details table view:
shows the name and the address of each TCB, whether it is a CICS TCB, below or above the 16-megabyte
line, the transactions being run in the TCB, the current task number
and the CPU time. In addition it shows the relationships between the
TCBs.
