Manage multi-user WLM environments
Use the WebSphere Application Server workload management (WLM) to control the performance of and the number of application server regions in z/OS .
We must define one or more server instances on one or more systems within the WebSphere node. Each server instance consists of a controller region and one or more servant regions. We must start controller regions as MVS™ started tasks, while servant regions are started automatically by WLM on an as-needed basis.
We can deploy applications within a WebSphere generic server. WebSphere servers are configured, by default, to allow only one servant region. The application server administrator must use the administrative console to allow the generation of multiple servant regions.
Tasks
- Configure the application servants setting. Configure the application server minimum/maximum servants setting as follows:
Min servants <= number of possible service policies <= max servants
- To change the minimum and maximum number of servant instances using the administrative console, select Servers > Server Types > WebSphere application servers > server. Click Java and Process Management > Server instance. Check the box Multiple Instances Enabled and type the minimum and maximum number of servant instances.
