An explanation of the difference between a DFHSTUP transaction report and an RMF workload report

Figure 51 shows the significance of the difference between the performance reports created for the region by DFHSTUP, and those generated by the RMF™ workload activity report for the reporting performance group number (RPGN).

Figure 51. CICS MRO transaction workflow
 In this example, a transaction arrives in VTAM, and moves to the TOR, then the AOR. It moves between the AOR and a database region (IMS or DB2) a couple of times. When this activity is completed, the transaction moves from the AOR back to the TOR, then departs via VTAM. z/OS system services (including WLM) are used in all the regions, but the transaction is actually classified by WLM when it is in the TOR for the first time.

If you are not familiar with the RMF workload activity report, see Understanding and using RMF workload manager data for more information.

CICS® transaction manager global statistics (see Transaction statistics) include ALL transactions in all regions in the interval or summary reports from DFHSTUP, but the MVS™ WLM workload activity report includes only the transactions in Begin-To-End (BTE) phase and EXEcution (EXE) phase. For WLM reporting purposes, the EXEcution phase applies to only routed transactions in the AOR.

In the terminal-owning region (TOR), the WLM reports for a given transaction are included in the RMF workload activity reports for the RPGN defined for the service class (for example, CICSPROD). In the application-owning region (AOR), notifys for routed transactions are included in the RMF workload activity reports when reporting EXEcution phases in the CICS AOR. Transaction WLM notifys for mirror transactions are ignored by the MVS WLM when reporting EXEcution phases in the CICS FOR.
