Define a Workload Manager Scheduling Environment as a Prerequisite Resource

SSM can define the status of a Workload Manager (WLM) scheduling environment as a prerequisite resource. A special naming convention must be used to specify the status of a WLM environment as a resource. The format is:

System.WLM.*SCHENV.Name

System

Specifies a valid z/OS system name that is known to WLM

Name

Specifies the WLM scheduling environment name. Name can be up to 16 characters in length.

WLM

Provides a placeholder that must be used in the SSID position for WLM resources if System is specified.

To access the status of only the local WLM, specify the following:

*SCHENV.Name

Notes:

• The WLM scheduling environment is the only cross-system resource that SSM evaluates without asserting a process event.
• The status of a WLM scheduling environment cannot be used as a subrequisite resource.
• The status of a WLM scheduling environment can be used by SSM to recognize an abstract condition such as Prime Shift or Batch Window.

The ability of SSM to read the status of a WLM scheduling environment eliminates the need for it to compute the status itself. This increases the efficiency of SSM and avoids the possibility that SSM will compute a WLM status differently than WLM itself because of sample timing differences.
