The HPO Activity Log is a repository for QMF session activity and object usage information. For example, when an object is erased from the system, the object name, the user ID of the person who issued the erase command, and the date and time will be recorded. All QMF object activity, including ad hoc activity, is tracked.
The HPO/Governor module writes to the HPO Activity Log data sets. A batch job, automatically generated by the HPO Activity Log JCL facility, is run periodically to copy the HPO Activity Log data sets to the HPO Activity Log tables.
An exit is provided from the HPO/Governor module to allow custom processing against the activity log records before they are written to the HPO Activity Log data sets. Each log record can be examined and marked for inclusion into or exclusion from the log. This exit can be used to selectively track QMF object activity. Sample assembler source code for this exit is provided in QMFHPO.SRAASAMP in the member named RAAOBJX.
