Assign the Core Group Policy

To enable high availability and workload management in the cluster, the installer creates a core group policy for the message engine. This policy, IMSPolicy, defines the preferred cluster member to use for the message engine. If that cluster member fails, the message engine switches to another cluster member, but returns to the preferred cluster member when it becomes available again.

Perform the following procedure once for each cluster member to add cluster members to this policy. For more information about this topic, see Setting up Preferred Servers in the Default Messaging Provider section of the WebSphere v7 System Management and Administration Redbook.

To assign the core group policy to cluster members

1. In the WebSphere Console, locate the configuration page for the policy created by the installer.
2. Select the cluster member you want to configure as the preferred cluster member for the policy.

   Do not select node agents or the Deployment Manager.

   The first cluster member in the list is the one that the messaging engine uses by default. Move the cluster member up or down in the list until they appear in the order in which they should be used.

3. Click OK to save the changes.
4. Repeat this procedure for each cluster member.
