Workload Management task
The Workload Management task in z/OSMF provides a browser-based user interface that you can use to manage z/OS® Workload Manager (WLM) service definitions and to provide guidelines for WLM to use when allocating resources.
Getting started
To get started with the Workload Management task, select and double-click the Workload Management task from the z/OSMF desktop. The Overview tab on the Workload Management page is displayed.
The Overview tab is the launch point for the actions that your user ID is authorized to access within the task. Select one of the actions listed.
Key features
- Define, modify, view, copy, import, export, and print WLM service definitions.
- Install a service definition into the WLM couple data set for the sysplex.
- Activate a service policy.
- View the status of WLM on each system in the sysplex.
- Analyze a service policy with SMF performance data and review recommendations for proactive problem identification and prevention.
For more details about the features provided in the Workload Management task, see Table 1 or view the z/OSMF Workload Management demonstration, which is provided on the IBM® Education Assistant website.

Feature | Description |
---|---|
Customize settings for the Workload Management task. | The Workload Management task allows
you to specify the settings to use for the task. Customizable settings include:
To display the Settings tab, on the Overview tab, click Settings. |
Import existing service definitions. | The Workload Management task allows
you to manually import service definitions that reside in a file on your local workstation or in a
data set on the z/OSMF host system. Note: The Workload Management task automatically imports
the service definition that is installed in the WLM couple data set.
For information that explains how to import a service definition, see help topic Importing service definitions from the local workstation or Importing service definitions from a host data set. |
Work with service definitions in editable tables. | The Workload Management task allows
you to edit service definition items directly in the table. The key advantage of this feature is
that you can edit an item and, simultaneously, view the properties of that item and other items
listed in the table. For example, this feature allows you to modify a service class and view the goals that were specified for other service classes in the service definition. For information that explains how to edit a service definition, see help topic Modifying service definitions. |
Experience real time error checking and view built-in recommendations for service definitions. | The Workload Management task
performs automatic error checking as you edit service definition items, and provides immediate
feedback on data validation errors. The Workload Management task also provides built-in recommendations that give you tips on how to optimize service
definitions and reduce common specification errors. Data validation errors and recommendations are indicated by an icon that is displayed near or in the field. If present, click the icon to view the validation errors or built-in recommendations. |
Preview and print formatted service definitions and policies. | The Workload Management task allows
you to view and print an HTML formatted version of a service definition and service policy with
overrides applied. For information that explains how to print a service definition, see help topic Printing service definitions. |
Install service definitions and activate service policies. | The Workload Management task
provides a wizard that guides you through the steps required to install a service definition into
the WLM couple data set and activate a service policy. For information that explains how to install a service definition and activate a service policy, see help topic Installing service definitions. |
Manage the service policies in the installed service definition. | The Workload Management task allows you to activate, print, or view the service policies that are defined in the installed service definition. For information that explains how to activate, print, or view a service policy, see the following help topics: |
Monitor the WLM policy activation status. | The Workload Management task allows
you to monitor the WLM policy activation status, to view the status of WLM on each system in the
sysplex, and to view details about the installed service definition and the active service
policy. To display the WLM Status tab, on the Overview tab, click WLM Status. |
Analyze a service definition and review performance recommendations. | The Workload Management task
allows you to analyze a service definition with SMF performance measurements that were collected
while your service policy was active. The WLM Policy Advisor provides data visualizations that
compare your definition with actual performance data, to uncover potential weak points in your
settings. The Policy Advisor also recommends improvements with links to directly modify the
associated service definition or service policy overrides in a Service Definition tab. For more information, see Policy Advisor. |
