How do I Update Cluster Configuration Using XML When DB is Used for Configuration?

Once a cluster is enabled in server_config.xml, the cluster topology and properties are defined in the cluster_config.xml. Cluster nodes, topology, persistence (EJB/Web), and Load Balancer will be specified here. After the initial configuration of the cluster, the cluster configuration may be modified using the Console or the XMLs.

In a file-based persistence, once the config XMLs are modified in any of the nodes and the cluster is restarted, the new configuration takes effect and is synched-up with all other nodes.

When DB is used for configuration persistence, use the following steps need to update the configuration in the DB, using local XMLs to provide the information:

• The cluster must be stopped.
• In any of the nodes, update the required config XML.
• Start the node, where the XMLs were modified:
• After any change in the configuration, to update the database, start the cluster node with the following option: com.pramati.Server -node <NODENAME> -updatelocalconfig.
  This updates all of the configuration files.
• To update specific configuration changed manually, start the cluster node with the following startup option: com.pramati.Server -node <NODENAME> -updatelocalconfigfor <SERVICENAME><SERVICENAME>.

Note: Only this node needs this option and the rest automatically use the updated configuration.
