This concept is an explanation of how WebSphere® Application Server for z/OS® uses the workload management (WLM) function of z/OS to start and manage servers in response to workload activity.
Each J2EE application server in a WebSphere Application Server for z/OS cell uses WLM to start servants as WLM application environments. Thus, each application server must be associated with a WLM application environment name. The "Cluster transition name" in the WebSphere Application Server for z/OS configuration is used as the WLM application environment name.
