Stopping a cluster

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

Before you begin

Make sure there is no work in progress; performance monitoring infrastructure counters can indicate whether all queued work is complete. In addition, prevent new work from starting by disabling HTTP and IIOP traffic on the cluster members and quiescing the service integration buses.

About this task

If you use a deployment environment pattern of Remote Messaging or Remote Messaging and Remote Support, there can be multiple clusters that depend on one another. If such a case exists, stop the clusters in the following sequence:
  1. Application deployment cluster
  2. Support cluster (CEI)
  3. Messaging infrastructure cluster

Procedure

  1. From the administrative console of the deployment manager, click Servers > Clusters > WebSphere application server clusters.
  2. Select the cluster you want to stop.
  3. Click Stop or Immediate Stop to stop the cluster.
    • Stop halts each server in such a way that the server can finish work in progress. This option allows failover to another cluster member.
    • Immediate Stop halts each server quickly, ignoring any current or waiting tasks.
