z/OS User Exits › z/OS Batch User Exits › TIRBURTX—Ultimate Retry Limit Exit › Purpose

Purpose

The Ultimate Retry Limit Exit allows the user to specify a maximum value for the TRANSACTION RETRY LIMIT system attribute. This value may never be exceeded, either by a SET TRANSACTION RETRY LIMIT statement in an action diagram, or by the Default Retry Limit Exit.

For an explanation of when and how the TRANSACTION RETRY LIMIT system attribute is used see Default Retry Limit Exit in this chapter.

Once the number of retries, as indicated by the TRANSACTION RETRY COUNT system attribute, reaches either TRANSACTION RETRY LIMIT or the value specified by the Ultimate Retry Limit Exit, no more retries can occur, and the application will fail with a runtime error if the last retry attempt was unsuccessful.
