Job-submit exit

The job-submit exit is called when IBM Tivoli Workload Scheduler for z/OS is about to submit a batch job or start a started-task. A common use for this exit is to assign a submitting user ID. If you do not alter the submitting user ID, all jobs submitted by IBM Tivoli Workload Scheduler for z/OS are, by default, performed under the user ID of the IBM Tivoli Workload Scheduler for z/OS address space that performs the submission.

Security is often performed through the RUSER field, but you can also use the exit to build a LOGONID card if your installation standards require this. You can determine the submitting user from a variety of sources. These include:

• Job name specified in the JCL
• Job accounting information
• Programmer name field
• Occurrence owner ID
• Occurrence authority group ID.

The SEQQSAMP member EQQUX001 contains a sample job-submit exit. This sample assigns a specific user ID based on the job name defined in the operation.
