PRGDLAY

The PRGDLAY system initialization parameter specifies the BMS purge delay time interval that is added to the specified delivery time to determine when a message is to be considered undeliverable and therefore purged.

PRGDLAY={0|hhmm}

This time interval is specified in the form hhmm (where hh represents hours from 00 to 99 and mm represents minutes from 00 to 59). If PRGDLAY is not coded, or is given a zero value, a message remains eligible for delivery either until it is purged or until there is a cold start of temporary storage.

Note: If you specify PRGDLAY as a SIT override, you must still specify a 4-character value (for example 0000).

The PRGDLAY facility requires the use of full function BMS. Note also that you must code a PRGDLAY value if you want the ERRTERM|ERRTERM(name) parameter on EXEC CICS ROUTE commands to be operative.

The PRGDLAY value determines the interval between terminal page clean-up operations. A very low value causes the CSPQ transaction to be initiated continuously, and can have a detrimental effect on task-related resources. A zero value stops CSPQ initiating terminal page clean-up. However, this can cause messages to stay in the system forever, resulting in performance problems with long AID queues or lack of temporary storage. The actual purge delay time interval specified is dependent on individual system requirements.
