Add a server to a PolicyCenter cluster

Procedure

  1. Deploy the current cluster configuration WAR or EAR file to the server that you intend to add to the PolicyCenter cluster.
  2. Verify that this configuration has parameter ClusteringEnabled set to true in the configuration’s config.xml file.
  3. If using the config.xml server registry, you must set the serverid attribute for this server to a unique value within the cluster.
    If you use a non-unique serverid value, the server with the duplicate ID does not start and does not join the cluster. See Understanding the PolicyCenter server environment.
  4. Start the new server.

Results

After you start the new server, it connects to the cluster and compares its configuration with the cluster configuration stored in the PolicyCenter database. It performs a checksum of the config.xml file and checks the config subdirectories. If the configurations differ, the server fails startup and PolicyCenter writes failure messages to the log file.
