Multiprogramming Activity Report

This report depicts concurrent program or job activity during each defined interval for a maximum of 99 active programs or jobs. Management can easily identify production work that creates resource contention by noting peak activity periods which have unusually high paging and I/O activity.

• The shift 1 start time is taken from the SYSUSE1 statement, along with the date on which the day (24-hour period) begins.
• The data for the report is job level or step (program) level data, as indicated at the top of each column.
• The headings for the data elements being displayed for each program or job are also displayed at the top of each column. These are selected by placing MPA field ID entries on the SYSUSE2 statement.
• The headings for the totals shown on this report appear in the last column. The Multiprogramming Factor is always shown, along with the three data elements selected on the SYSUSE2 statement.
• The vertical time-of-day axis is displayed on the left of the report. The increment for each time interval is specified on the SYSUSE1 statement.

You can select this report at program or job level via the SYSUSE1 statement and may select three of the following elements for display (the first two elements selected are reported for all six report columns; the third element is reported in the TOTAL column only):

• CPU time
• Elapsed CPU rate (CPU/Elapsed)
• I/O index (Total EXCP Count/CPU)
• CPU page rate (Total Page Count/CPU)
• Elapsed page rate (Total Page Count/Elapsed)
• Total EXCP count
• Total page count
• CPU utilization rate (CPU/Interval Size)
• Service rate (Service Units/Active)
