Defining the started tasks to z/OS Workload Manager (WLM)
This is part of the larger task of customizing your z/OS® environment.
With z/OS workload management (WLM), you define performance goals and assign a business importance to each goal. You define the goals for work in business terms, and the system decides how much resource, such as CPU and storage, should be given to it to meet the goal. Workload Manager constantly monitors the system, and adapts processing to meet the goals.
WebSphere® Message Broker automatically defines the JOBACCT token for each execution group started, so that the broker systems administrator can use WLM classification to map the JOBACCT token to specific Service and Report classes.
Each execution group can be assigned to a different Service and Report class. Whenever an execution group address space is started, the STEPNAME is assigned to the JOBACCT token.
When an execution group address space is started on z/OS, the STEPNAME is derived from the execution group label; the STEPNAME is defined as the last eight characters. Any characters that are not valid for a STEPNAME are replaced with the @ character.
For example, an execution group address space with the label MyExecutionGroup, has a STEPNAME of IONGROUP and assigns this same value to the JOBACCT.
The STEPNAME/JOBACCT is not guaranteed to be unique across multiple execution group address spaces on the same LPAR. If you require a unique STEPNAME/JOBACCT across multiple execution groups, you must use a suitable execution group naming standard.
