Stopping clusters

Use this task to stop a cluster and any application servers that are members of that cluster.

If we use the Windows Services facility to start and stop application servers that are part of a cluster, remember that the cluster state does not always update correctly. For example, if a cluster is running and you stop a cluster member through the Services GUI, the cluster state remains as Started even though the server is no longer running.

We can stop all application servers that are members of the same cluster at the same time by stopping the cluster.

  1. Click Servers > Clusters > WebSphere application server clusters > in the console navigation tree to access the Server Cluster page.

  2. Select those clusters whose members you want stopped.

  3. Click Stop or Immediate Stop.

    • Stop halts each server in a manner that allows the server to finish existing requests and allows failover to another member of the cluster. When the stop operation begins the cluster state changes to partially stopped. After all servers stop, the cluster state becomes Stopped.

    • Immediate Stop brings down the server quickly without regard to existing requests. The server ignores any current or pending tasks. When the stop operation begins, the cluster state changes to partially stopped. After all servers stop, the cluster state becomes Stopped.

Results

All application servers in the sysplex associated with this cluster are issued a request to stop. In addition, a stop can be issued against each individual server from the MVS™ console. To shut down the product environment on a specific system, stop that system daemon. Stopping the system daemon brings down all other server instances on the system. To bring the product down on all of the systems, stop the daemons on all systems. When you stop the location service daemon on one system, it does not bring down the servers on the other systems.
