Adding Nodes to a Cluster

This procedure describes how to add one or more nodes to an existing cluster.

  1. Install Spectrum Technology Platform and modules on the server that you want to add to the cluster.
  2. Open the following file in a text editor:


  3. Edit the properties in this file as described in Cluster Properties.
  4. Save the file.
  5. Open the server/conf/ on all other servers in the cluster, and in each file add the host name or IP address of the new server added to the cluster (spectrum.cluster.seeds).
  6. Stop all the Spectrum Technology Platform nodes in the cluster. For more information, see Stopping a Cluster. If your cluster has a separated configuration database cluster, you only need to stop the server cluster, not the configuration database cluster.
    Warning: To prevent data loss you must stop the cluster by following the procedure described in Stopping a Cluster.
  7. Start all nodes in the cluster consecutively.
    Note: Make sure that you start node 2 within only a few seconds after starting node 1, and repeat this for each remaining node.
