Adding Modules to a Cluster

After installing a cluster you may decide to add additional modules. This procedure describes how to add one or more modules to an existing cluster.

  1. Shut down all the Spectrum™ Technology Platform nodes in the cluster.
  2. Choose a node where you will first install the module. On that node, open the following file in a text editor: server/app/conf/spectrum-container.properties.
  3. Set spectrum.cluster.enabled to false.
  4. Save and close the file.
  5. Install the module or modules you want to add. For instructions, see the Spectrum™ Technology Platform Installation Guide.
  6. Start the server.

    The server starts up in standalone (non-clustered) mode.

  7. Wait for the server to fully start up, then stop the server.
  8. Open server/app/conf/spectrum-container.properties in a text editor and set spectrum.cluster.enabled to true.
  9. Save and close the file.
  10. Start the server.

    You now have a cluster of one with the new module installed.

  11. Start up each of the other nodes.
