Configuring J2EE Cluster Using Server Administration Service

• Configure nodes for Lookup, HTTP and HTTPS Port values.

• Add new nodes to the cluster by providing values as Name, Type, Host, Lookup, HTTP and

HTTPS Port values.

• Delete existing nodes.

• Edit the failover details for the Cluster.

Click ‘Save’.

Starting Cluster

To start the cluster:

1 On the Server Administration Service, click ‘Start’ against the required cluster under J2EE Server

Clusters section. This displays details of the nodes that are defined for the cluster along with an

option to specify JVM options, and the Login details of the user.

2 Select all the nodes that you want to start.

Note: You can click on the name of the node to view the node details.

3 Enter the password for the relevant realm. The default value for the ‘system’ realm is pramati.

4 Click ‘Start’.

The Status panel displays the related messages as the specified cluster nodes start. A successful start

displays the option to ‘Connect’ to the cluster.

Connecting to Cluster

To connect to the cluster:

1 Click ‘Connect’ against the cluster. The login page appears.

2 Enter the username and password for the realm. For the system realm, the default values are root

and pramati.

3 Click ‘Login’.

You are connected to the selected node and details related to the connected node are displayed on

the Console Home page.

Deploying an application on Cluster node

Deploying an application on a cluster node is the same as deploying it on a Standalone Server.

However:

• An application deployed on one node is available to all the running nodes of the cluster.

• Even if a cluster node (say N2) is shutdown when the application is deployed on another cluster

node (say N1), the application is available on N2 after you start it.

• All resources used by an application, such as Datasources, Connector, Mail, etc. are available on

all the nodes of a cluster.

To deploy an application on a cluster node:
