How to Create a Cluster

Upon completion of this task, the following changes will have been made:

• Your target instance is a cluster.

• One ClusterMaster component is installed in the selected virtual host.

Before You Begin

To create a cluster, you must already have a J2EEInstaller component installed. For more information, see How to Deploy the J2EE and Web Cache Topology.

Steps

1. In the Common Tasks section of the N1 Grid SPS browser interface, select Oracle App Server 10g.

2. In the Cluster Management section of the Oracle App Server 10g Common Tasks page, click Create.

3. On the Plans Details page, click Run.

4. Select the virtual host that you want to target.

   The host must be a member of the ClusterHostSet. Also, the host must not contain a ClusterMaster component or a ClusterMember component. You can select more than one virtual host.

5. Verify that the target host set is not selected.

   The checkbox in front of the target host set should be empty. Otherwise, the plan will try to install in the host set plus the hosts that you selected in the previous step

6. Click Run Plan (includes preflight).
