Adding and Removing Cluster Members

Consider the following information before adding or removing cluster members in the Enterprise Manager:

Before adding a new realm to a cluster, you must connect to the realm. For more information about how to connect to a realm, see Connecting to Multiple Realms.

If the realm you want to add has local stores with names matching any store on the cluster, the realm will not be added to the cluster. This prevents naming clashes in the cluster.

You can add and remove cluster members in the same operation.

To modify a cluster in the Enterprise Manager

1. Expand the Clusters node.

2. Select the cluster you want to modify and right-click it.

3. Click Modify Cluster Members.

4. Do any of the following:

From the Available Realms list, select realms to add to the cluster. Click OK.

Any existing cluster resources are also created on the newly added realms.

From the Cluster Members list, select realms to remove from the cluster and click OK. Then specify whether to delete all cluster-wide resources on the realms that you removed or whether to convert the cluster resources to local ones.

Converting the cluster resources to local ones keeps any data contained in the cluster resources.
