Workload management (WLM)

Workload management optimizes the distribution of incoming work requests to the application servers, enterprise beans, servlets, and other objects that can most effectively process the requests. Workload management also provides failover when servers are not available, improving application availability.

WebSphere for z/OS requires that z/OS run workload management in goal mode. If your system runs in compatibility mode, you must implement goal mode. For details on workload management, see z/OS MVS Planning: Workload Management, which is available on the z/OS Internet Library Web site . You might also find z/OS MVS Programming: Workload Management Services helpful.

In addition to setting up workload management in goal mode, you need to define workload management policies for your application servers.

Note: To get started, you do not need to define special classification rules and work qualifiers, but you might want to do this for your production system.

Workload management provides the following benefits to WebSphere Application Server applications:

In the WebSphere Application Server environment, you implement workload management by using clusters, transports, and replication domains.
