Use PRETAIN=TABLE When Reports are Under ERO Retention

We recommend setting PRETAIN=TABLE with a catch-all entry in the ERO table. This makes the ERO table statements the single point of control for the retention of the ERO reports.

Business Value:

Using PRETAIN=TABLE provides more efficient utilization of DASD and TAPE resources.

Additional Considerations:

The PRETAIN parameter has two settings - INIT and TABLE. This controls when an expired report is physically removed from DASD storage and logically removed from TAPE storage. When this parameter is set to TABLE, reports are removed when the ERO retention criteria is met. The INIT setting causes reports to remain on DISK and TAPE until both the ERO retention and the NGENT/NGEND settings have met.
