Batch Manager

The Batch Manager is similar in function to the Dialog Manager. The Batch Manager controls the dialog flow between procedure steps. Only forward transfers are allowed in batch processes (links are not allowed).

Batch applications use three special files. They are referenced by the DDNAMES (data definition names) TIRIOVF, TIRMSGF, and TIRERRF. CA Gen accesses these special files through the CA Gen-provided runtime routine.

• TIRIOVF is the data set used to pass data (views and Batch Manager control information) from one procedure step to another on a dialog flow.
• TIRMSGF is the Batch Manager Message File. It provides a trace of procedure steps executed, exit states set, exit state messages issued, and dialog flows taken.
• TIRERRF is the Batch Manager Error Message File. In the event of a failure, error messages and diagnostic information are written to this file. The messages and diagnostic information will help you determine the cause of the failure.
