How to Remove a J2EEInstaller Component from a Cluster

When an Oracle App Server instance leaves the cluster, the cluster repository is copied into the file-based repository of the instance. From this point on, the instance uses its own repository and commands issued to this instance to modify OC4J instances or applications only affect this instance.

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

Your target instance is not a member of the cluster.
One ClusterMember component is uninstalled in the selected vhost.
One Oc4jHolder instance is installed in the instance that left the cluster.
One Oc4jHolderHT vhost is created by the Oc4jHolder component.
One Oc4jInstance (home) is installed in the Oc4jHolderHT vhost.

Note –

The application server instance leaving the cluster inherits a copy of all the OC4J instances and applications that were deployed in the cluster. N1 Grid SPS limitations cannot represent this change, therefore, this instance will be out of sync with the Oracle application. The home OC4JInstance will be created, but other OC4J instances in the cluster and the applications that they contain will be missing. To resynchronize this component with Oracle, you must use a markOnly install or set the full Install parameter to false when you run plans.

Before You Begin

To remove a J2EEInstaller component from a cluster, the component must be a member of a cluster. See How to Add a J2EEInstaller Component to an Existing Cluster.

Steps

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

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

On the Plans Details page, click Run.

On the Plans Details Run page, select the virtual host that you want to remove from the cluster.

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.

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 remove components in the host set plus the hosts that you selected in the previous step

Click Run Plan (includes preflight).
