Broadcasting events

The LU that your ATP sends requests to is owned by an HCL Workload Automation for Z address space where the APPC subtask is started. When you send a CREATE request to the LU, the address space processes the request and creates an event. If you want to report an event to more than one HCL Workload Automation for Z address space, or an event writer is not started in the address space that owns the target LU, you must broadcast the event.

To broadcast an event, specify SUBSYSTEM_NAME in the APPSEL section but do not provide a name in the APPVAL section, or provide the name MSTR in APPVAL. The event is sent using the subsystem interface (SSI) to all HCL Workload Automation for Z address spaces started on the same z/OS image as the target.
