Designing an Event Exit

The event exit is available only through the IXCARM REGISTER request. This exit:

Gets control any time the element is to be restarted, but only after the workload restart and element restart installation exits have completed processing
Note: When this exit runs, all resource managers have completed processing and the address space the element was originally running in is no longer addressable.
Has to be able to be loaded by every MVS™ system in the sysplex that is connected to the ARM couple data set
Runs on the system on which the element is to be restarted
Receives the address and length of a copy of the automatic restart manager event-exit parameter list, mapped by IXCYEVE. The parameter list contains the address of the event exit parameter list if EVENTEXITPL was specified on the IXCARM macro.
Sets a return code that tells automatic restart management whether to proceed with the restart.
