The following information describes some of the key functions available
in the Workload Management task in z/OSMF:
- Display list of service definitions.
- The Workload Management task provides a list of the WLM service
definitions that have been defined in z/OSMF along with history information
(for example, when the service definition was installed or modified),
messages, and user activity. The list of service definitions is retrieved
from the service definition repository, which refers to the directory
in the z/OSMF data file system in which the data for the Workload
Management task is stored.
- Work with multiple service definitions.
- In the Workload Management task, you can work with multiple service
definitions simultaneously. To do so, open the service definitions
with which you want to work in its own View, Modify, Copy, or Print
Preview tab. You can also define multiple service definitions at the
same time by opening several New tabs.
- Install service definitions.
- The Workload Management task provides features that you can use
to install a service definition into the WLM couple data set for the
z/OSMF host sysplex.
- Extract the installed service definition.
- The Workload Management task automatically extracts the service
definition that is installed in the WLM couple data set for the z/OSMF
host sysplex and stores it in the service definition repository so
that you can view it, modify it, or activate one of its service policies.
- Import and export service definitions.
- The Workload Management task provides features that you can use
to import a service definition from or export a service definition
to your local workstation or a sequential data set on the z/OSMF host
system. The exported service definition is formatted so that it can
be opened with the z/OS® WLM
Administrative Application (also called the WLM ISPF application).
- Provide table view and print preview of the service definition.
- The Workload Management task provides two views of a service definition:
- Table View. The table view displays the parts of the service
definition as tables. You can display the table view by opening the
service definition in the New, View, Modify,
or Copy tab. If you open the service definition
in the New, Modify,
or Copy tab, you can modify the service definition.
In the View tab, you cannot modify the service definition.
- Print Preview. The print preview presents the service definition
in HTML format and allows you to select which parts of the service
definition you want to preview or print. You can display the print
preview by opening the service definition in the Print
Preview tab.
- Activate service policies.
- In the Workload Management task, you can specify which policy
to activate when you install a service definition or you can activate
a service policy that is defined in the service definition currently
installed in the WLM couple data set for the sysplex.
- Preview service policies with overrides applied.
- The Workload Management task allows you to preview an HTML formatted
version of the service policy with overrides applied. The HTML formatted
service policy contains the information that would be included in
the policy if it were activated. To preview a service policy, open
the policy in the Print Preview tab.
- View the sysplex status.
- The Workload Management task provides an HTML formatted view (WLM
Status tab) of the same data that is retrieved when you
issue the D WLM,SYSTEMS command on the z/OS console.
Specifically, the WLM Status tab displays
the status of WLM on each system in the sysplex, and lists details
about the installed service definition and the active service policy.
- Define settings.
- The Workload Management task provides a shared location (Settings tab)
where you can specify for how long to keep the service definition
history and define the code page, time zone, and backup sequential
data set for the sysplex. You can also enable consistency checking
between z/OSMF and the WLM couple data set, and indicate whether you
want the Workload Management task to display or suppress information
messages.
Actions that require the Workload Management task to interact with
the sysplex are limited to the sysplex in which the z/OSMF host system
is a member. Such actions include installing a service definition,
activating a service policy, viewing the sysplex status, and so on.
If you want to interact with another sysplex, z/OSMF must be installed
on a system in that sysplex and you must log into that z/OSMF instance.
You can use the service definition import and export functions to
copy a service definition from one z/OSMF instance to another z/OSMF
instance.
To display the Workload Management task, expand the Performance
category in the z/OSMF navigation area and select Workload
Management.
Figure 1 shows the main
panel for the Workload Management task. The Overview tab
serves as the launch point for the actions that your user ID is authorized
to access within the Workload Management task. To start using the
Workload Management task, select one of the actions listed in the Overview tab.
