Click Next>>. ‘Step 2 of 3: Add Nodes’ page appears.

To add more than one node, provide similar details in the fields provided.

Enter the Session Persistence details. Select whether EJB and Web will have session persistence ‘In

Memory’ or ‘Database’. This makes sure that the state of a stateful session bean is passivated into a

database, and that the state of the bean is replicated on any running node during failover. This

database can be different from the database that stores the cluster details. Click ‘Next’.

A successful node addition prompts ‘New Cluster Test created successfully.’ in the Status panel. The

third step is to set the Session properties in case a failover happens. In the new page, you can:

• Replicate data on all the nodes of the cluster, or

• Maintain a backup on selected nodes of the cluster

Click ‘Save’ to return to the Server Administration Service main page. The new cluster is seen listed

here.

Modifying Cluster

On the Server Administration Service, click ‘Configure’ against the cluster that is to be modified

under J2EE Server Clusters section. A screen displaying the cluster details and the nodes that define

the cluster appears.

You can:

• View configuration details of individual nodes by clicking on their names provided as links.

• Specify the weight of the cluster nodes. This value is used for Load Balancing.

Table Provide a table name for the database, say ‘emp’. This is a mandatory field.
