Overview

This chapter describes how to archive Performance Monitor statistics so they can be used as input for Performance Monitor batch reports. Sample JCL and commands for running these batch reports are also provided.

Creating statistics archives

Before generating the Performance Monitor batch reports, you must archive the collected statistics to tape. This tape serves as input to the reports. Any number of archive tapes can be input to a single run.

The procedure for archiving statistics varies, depending on where the statistics are written to:

If statistics are written to the DDLDCLOG area of the dictionary, you archive using the ARCHIVE LOG utility statement (see Archiving Statistics From the DDLDCLOG Area).
If statistics are written to the system management facility (SMF) job accounting file (z/OS systems only), then you archive using the PMSMFEX macro (see Using SMF to Archive Statistics (z/OS only)).

Note: For more information about SMF and archive file record layouts, see Performance Monitor Record Descriptions.

Job-step restriction

You cannot request Interval Monitor and Application Monitor reports in the same CA Culprit job step. To get both sets of reports in one run, use two CA Culprit job steps. You can minimize tape handling by first using PMARPT90 and PMIRPT90 to produce machine-readable files of Performance Monitor statistics.
