Assigning the PowerExchange Listener to a WLM Service Class

The Workload Manager (WLM) is a z/OS component that dynamically manages the prioritization of request for z/OS shared resources such as storage, CPU, and I/O devices across one or more z/OS images based on service classes that you define. By assigning the PowerExchange Listener started task to the appropriate WLM service class, you can ensure that processes that access your z/OS data through PowerExchange meet the desired performance goals.

You define service classes by using IBM z/OS WLM tools, such as the WLM ISPF application. Each service class includes a goal and importance level, which prioritize work based on your business requirements. Because of the nature of the PowerExchange Listener task, Informatica recommends that you assign the PowerExchange Listener to a service class that has a velocity execution goal.
