Statistics utility program, DFHSTUP

The statistics utility program, DFHSTUP, prepares and prints reports offline, using the CICS® statistics data recorded on the z/OS® system management facilities (SMF) SYS1.MANx data sets.

To enable the CICS statistics domain to record interval statistics on these SMF data sets, you must specify ON for the STATRCD system initialization parameter. The other statistics record types (unsolicited, requested and end-of-day) are written regardless of the setting of the STATRCD parameter. For information about the SMF data sets, see z/OS MVS System Management Facilities (SMF). For information about what CICS data is recorded on the SMF data sets, see Introduction to CICS statistics. For information about interpreting CICS statistics output in the DFHSTUP report, see CICS statistics in DSECTS and DFHSTUP report.

Important: Always use the version of the DFHSTUP program from the same release of CICS as the data that it is to process.

The DFHSTUP extract statistics reporting function

The extract reporting facility provides a method of sending CICS statistics data to a user program that can process statistics records to create tailored reports.

Make these reports easy to review to avoid working through large amounts of data to determine if some corrective or preventive tuning action is required. You can identify the specific CICS regions, the time of day, and the type of CICS resources that might require further specific in-depth performance analysis. DFH0STXR and DFH0STXD are sample programs that are designed to use the extract reporting function. You can use these sample programs as supplied, or as a model on which to base your own programs.
