Scheduling the Reaper Program

The reaper program is a delivered PeopleSoft Application Engine program named PSPM_REAPER. The reaper program maintains the PeopleTools tables that the Performance Monitor uses to store performance data for current, real-time processing.

When the PSPPMSRV gets notified that a PMU has finished (it receives a STOP for an open PMU), it:

• Flags the corresponding start and update rows in the current PMU table (PSPMTRANSCURR) for deletion.

• Inserts a row for the completed PMU in the PSPMTRANSHIST table.

When the reaper program (PSPM_REAPER) runs, it:

• Deletes all rows in current PMU table (PSPMTRANSCURR) that are flagged for deletion.

• Sets the status to timed out for expired PMUs in the current tables.

To run the reaper program:

1. Select PeopleTools, and then Performance Monitor, and then Administration, and then Purge Performance Data.

2. Select or add a run control ID.

3. Click Run.

PeopleTools delivers a recurrence definition named PerfMon Reaper Recurrence, which is set to run every 15 minutes. Modify this recurrence definition, if necessary, and associate it with the PSPM_REAPER program to schedule the program to run at suitable intervals.

WARNING:

If you do not schedule the reaper program to run often enough, the PSPMTRANSCURR table will grow very large over time, and it may contain many old, open PMUs.
