Batch Manager

Batch processing, in this context, is a capability on IBM mainframes. This information about Batch Managers, therefore, applies primarily to an environment that supports batch processing. The Batch Manager can be created only in COBOL.

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). For more information about Batch Manager, see Host Encyclopedia Construction User Guide.

CA Gen batch applications use three special files. They are referenced in the job control language (JCL) by the data definition (DD) names TIRIOVF, TIRMSGF, and TIRERRF. CA Gen accesses these special files through the CA Gen provided runtime routine TIRBTCH.

• 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 those 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 helps you to determine the cause of the failure.
