Broadcasting events

The LU that your ATP sends requests to is owned by an IBM Z Workload Scheduler 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 IBM Z Workload Scheduler 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 IBM Z Workload Scheduler address spaces started on the same z/OS image as the target.
