MVS system name

The MVS™ system name, as it applies to an observation, represents the system on which the observation was finally serviced. In a non-sysplex environment the system name is the same as the name of the system where the observation request was made.

In a sysplex environment, the intent of the system name is to control an observation request based on the target system or servicing system name, which prevents a user from adding an observation request that targets a job that will execute on a system to which that the user does not have access.

In determining the resource profile to be used for authorization, Application Performance Analyzer derives the system name based on the status of the observation, the action to be performed, and the sysplex options specified on the observation request. For observation requests that are to be scheduled or are in schedule status in which the target system is specified, the target system name is used. If the target system is specified as * or ALL, an attempt is made to evaluate the user's authority based on the current system name and the system names of the systems in the sysplex group – if authority cannot be determined definitively, the request is provisionally accepted and user authorization will be performed again when the request runs. For completed or active observations, the system name used will be the servicing system name. See Examples for specific examples of how Application Performance Analyzer derives the system name.
