Managing included service classes

To manage an included service class filter for a workload condition, you can use the Included Service Classes page. To define, view, or modify an included service class filter use the New, View, or Modify actions on the Included Service Classes tab on the Workload Condition page.

The specification of included service classes filters is optional, however at least one importance filter or one included service class filter must be specified for a valid workload condition. All service classes listed in the Included Service Classes table can trigger provisioning when they are in the defined service class period. For each specified service class period additional provisioning criteria must be defined.

An included service class filter is identified by the name in the Service Definition, the Service Policy and in the Service Class field.
Table 1. Fields on the Included Service Class Filter page
Field Description
Service Definition Name of the z/OS® Workload Manager (WLM) service definition. The specified service class periods are only considered if this WLM service definition is installed.

To match the name of any service definition, select Any service definition.

Select Specify a value to specify a particular WLM service definition.
Service Policy Name of the service policy within the WLM service definition. The specified service class periods are considered if a service policy with that name is activated.

To match the name of any service policy, select Any service policy.

Select Specify a value to specify a particular WLM service policy.
Service Class Name of the WLM service class to consider.

To match the name of any service class, select Any service class.

Select Specify a value to specify a particular WLM service class.
Period Highest period of the service class that should be considered by the Provisioning Manager. This period and all periods with a lower period number are considered eligible to trigger provisioning. If a service class has fewer periods than this number, all periods are considered.
Provisioning PI Performance index threshold for provisioning. It must be a number from 1.3-10. If the performance index of a service class period is equal or higher than the specified value the Provisioning Manager considers the service class period to be suffering.
Provisioning Duration Number of minutes the performance index must exceed the specified provisioning PI before the Provisioning Manager considers a service class period to be suffering. It must be a number from 4-1440.
Deprovisioning PI Performance index threshold for deprovisioning. If the performance index of a service class period is lower than the specified value it is not considered to be suffering. The de-provisioning PI must be at least 0.2 less than the provisioning PI limit, and must be a number from 1.1-9.8.
Deprovisioning Duration Number of minutes the performance index must be lower than the deprovisioning PI before the Provisioning Manager considers a service class period to be no longer suffering. It must be a number from 4-1440.
PI Scope Indicates if the provisioning PI and deprovisioning PI values refer to the sysplex PI or the system PI of the service class period.

Select System to indicate that the performance index of the service class period on each system in the sysplex is used. The system PI is also referred to as the local performance index (local PI). This is the default and the recommended setting.

Select Sysplex to indicated that the performance index of the service class period within the sysplex is used. A sysplex PI should only be chosen if all systems joining the sysplex are defined to the provisioning domain. If you choose PI scope Sysplex, the Provisioning Manager monitors in addition to monitoring the sysplex PI also the system PI. Only if the monitored system is actually suffering, the Provisioning Manager starts to take actions.

Refer to Naming Conventions in order to find out which names are allowed.

Open the Defined Included Service Class Filters section to see the table of already defined included service class filters for the current workload condition to have a quick reference.
