Joining a node to a load balancing cluster
You can configure a Tivoli Integrated Portal Server to join an existing load balancing cluster.
Before you begin
- If you are joining a stand-alone Tivoli Integrated Portal Server instance to a cluster, ensure that you first export all of its data. Once you have joined it to the cluster, you can then import the previously exported data. Other nodes in the cluster should not contain any custom data and should effectively be new installed instances.
- Make sure you have successfully enabled load balancing following the steps in Setting up a load balancing cluster.
- Tivoli Integrated Portal should be installed to the node using the same cell name that is designated for the cluster.
- All console modules deployed to the cluster must be already deployed to the node that you intend to join.
- You should deploy any wires or transformations used by the nodes in the cluster.
- If the cluster is using any customization changes in consoleProperties.xml you must copy these changes and this file to the same location on the node that you intend to join.
- The node must be configured to the same LDAP with the same user and group definitions as all other nodes in the cluster.

What to do next
Add another node to the cluster, or if you have completed adding nodes, enable server to server trust for each node to every other node in the cluster.
Depending on the network dispatcher (for example, IBM HTTP Server) that you use, you might have further updates to get session requests routed to the new node. Refer to the documentation applicable to your network dispatcher for more information.
