How to Add a J2EEInstaller Component to an Existing Cluster

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

• Your target instance is a member of the cluster.

• One ClusterMember component is installed in the selected vhost

• The Oc4jHolder component and all its Oc4jInstance components are removed, because the instance now belongs to the cluster.

• The OC4J instances and applications of any member of the cluster are represented by the components installed in the Oc4jHolder component that belongs to the application server instance holding the ClusterMaster component.

Before You Begin

To assign a J2EEInstaller component to a cluster, the cluster must already exist. See How to Create a Cluster.

Steps

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

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

3. On the Plans Details page, click Run.

4. On the Plans Details Run page, 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. Type the value for the ORACLE_HOME_NAME of the J2EEInstaller component that contains the ClusterMaster of the cluster you want to join.

7. Type the name of the physical host on which the ClusterMaster component is installed.

8. Click Run Plan (includes preflight).
