Program statistics

Program statistics report the resource data collected by the loader for each program.

For public programs, these statistics are mapped by the DFHLDRDS DSECT. For private programs for applications that are deployed on platforms, these statistics are mapped by the DFHLDPDS DSECT. The statistics records for private programs have information about the application for which the program was loaded.

Programs that are defined as application entry points are not identified in the program loader statistics, and only a private program statistics record is produced for them.

Information about Java™ programs that run in a JVM is not included in the program statistics, because JVM programs are not loaded by CICS®. For this information, see JVM program statistics.

6.2 and later Program statistics containing zero count fields following a reset will be suppressed for interval, requested, and requested reset type statistics. This provides reduced SMF volume at most of the times CICS statistics are being generated, retaining the ability to use CICS statistics as a way to inventory CICS resources. For more information, see Introduction to CICS statistics.

Interpreting program statistics

Average fetch time is an indication of how long it takes z/OS® to perform a load from the partitioned data set in the DFHRPL or dynamic LIBRARY concatenation into CICS managed storage.

The average for each LIBRARY offset (Lbry ofst) of Program size / Average fetch time is an indication of the byte transfer rate during loads from a particular partitioned data set. A comparison of these values may assist you to detect bad channel loading or file layout problems.
