Workload Activity report

The Workload Activity report provides a transaction response time analysis by MVS™ Workload Manager (WLM) service and report class. This can be used in conjunction with the z/OS® Resource Measurement Facility (RMF™) workload activity reports to understand from a CICS® perspective how well your CICS transactions are meeting their response time goals.

The report processes all CMF transaction performance class records for network units-of-work containing multiple performance records as well as those with only a single performance record.

Two reports can be requested:
  1. Workload Activity List. This is a cross-system report that correlates CMF performance class data from single or multiple CICS systems for each network unit-of-work. Importantly, this report ties MRO and function shipping tasks to their originating task so that their impact on response time can be assessed.
  2. Workload Activity Summary. This report summarizes response time by WLM service and report classes.
To request the report, enter line action S against the Workload Activity Performance Report on the Report Set panel. If reports of this type have been previously specified, the list of Workload Activity Reports is displayed. Otherwsie, the Workload Activity Report panel is displayed for you to define your first report of this type.

This panel displays the list of Workload Activity Reports in this Report Set. You can select (edit), delete, or include/exclude any report, insert new ones, or rearrange them (move/copy).

The options and line actions are the same as those for the Performance List Reports panel, except there is no Report Form. See Performance List report.

To display the Workload Activity Report panel, enter line action S against the Workload Activity Performance Report on the Report Set panel, then if the list of previously specified reports is displayed, enter line action S against a particular report in the list.

Use this panel to specify report options and record selection criteria for the Workload Activity report. The report format is fixed. The only mandatory option is the Report Output DDname. You can let the other options default.

The report options are the same as those for the Performance List Report (see Performance List report), except there is no Report Form, you can select the reports you require, and there is an additional processing option:
Reports Required
Enter / to select the reports you want produced.
  • Select List to request the Workload Manager Activity List report, a detailed listing of transaction activity in begin-to-end (BTE) phases, completed execution phases (EXE Y), and incomplete execution phases (EXE N). This report requires an external sort.

    You can choose how tasks are sorted within UOW in the List report: by descending stop time (the default order) or ascending start time. This option generates the operand TASKORDER(START|STOP).

  • Select Summary to request the Workload Manager Activity Summary report.

    Select Include EXE Y tasks to summarize transactions in both completed execution phases (EXE Y) and begin-to-end (BTE) phases, otherwise the report contains BTE transactions only. EXE N transactions cannot be summarized. The Summary report with both BTE and EXE transactions requires an external sort.

    The default is the Summary report with BTE transactions only. It is a very quick report as no external sort is required.

Peak Percentile
This option applies to the Workload Activity Summary report. Specify a number between 50 and 100 to report the response time within which that percentage of transactions completed. Computations assume a normal distribution. For example, 95 shows the response time that 95% of transactions completed within. The default is 90.

CICS PA JCL generation translates this value to the PEAK(percentile) operand.

CICS PA provides a default Report Output DDname in the format WKLDnnnn where nnnn is 0001-9999.
