DB2 graphic QMF Version 8

Monitor VSAM file maintenance

Monitor obtains QMF session information from the Monitor VSAM file (which is written by the HPO/Governor module). During normal usage, more and more data will be written to this file. The Monitor online facility can generate and submit JCL to clean up this file.

Note:
If the Monitor VSAM file fills up, Monitor will automatically stop recording QMF session information.

The required frequency of cleanup is related to the amount of QMF activity at your site and the space allocation of the VSAM file. Once the data in the file is purged, it is no longer available for display from the Monitor online facility. Therefore, if a daily purge is scheduled, data will only be available for the last 24 hours.

Selecting option 2 from the Monitor Selection Menu brings you to the VSAM File Cleanup JCL panel. You can also invoke this panel by issuing the following TSO command:

CALL 'QMFHPO.SRAALOAD(RAAMAIN)' 'MN 2'

This panel allows you to specify the information needed to create the JCL and to run the cleanup batch job.
