4.3.5 Defining the Cluster Nodes
Once you have completed the operations in Installing Node 1 for Repository and Admin Servlets, Installing Additional Nodes for Repository Servlets, and Installing the Load Balancer Proxy, you must start up the cluster and define each cluster node on the 'Clustering' page of Enterprise Manager. Follow the steps below.
1. Start the server on Node 1.
2. Start the servers on Node 2 through Node N.
3. Start the Load Balancer (Proxy) node.
4. Launch Enterprise Manager on Node 1.
Each cluster node must have an unique license key.
5. Open Enterprise Manager on Node 1. On the 'Server' > 'Cluster' page, add Node 2 through Node N to the 'Cluster Servers' panel if not already listed.
6. If you want a node to be used by the Scheduler to process scheduled reports, select 'Use this server for scheduled reports'. See Using a Clustered Environment for instructions on running the Scheduler.
To manage a node, select it from the list of existing cluster nodes. You can prevent new sessions from being sent to the node by pausing it (click the 'Pause'/'Resume' button). Then you can wait until the existing users logoff. This is useful if a node requires maintenance, and you do not wish existing users to be negatively impacted. You can remove the node by clicking the 'Delete' button. To reload the sree.properties file for all nodes, click the 'Restart All' button.
