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.
WebSphere Application Server for z/OS requires that z/OS Workload Management run in goal mode. If your z/OS system is running WLM in compatibility mode, follow the instructions in z/OS Planning: Workload Management (SA22-7602) to implement goal mode before proceeding with WebSphere Application Server for z/OS customization.
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.
WebSphere Application Server for z/OS makes use of dynamic WLM application environments when available. (The WLM service that added dynamic application environments is a prerequisite for WebSphere Application Server for z/OS.) Therefore, you do not need to use the WLM ISPF panels to manually create application environments for WebSphere Application Server for z/OS.
