Upgrading claster

When you're upgrading from a version prior to 4.5.0 (and after 3.0.0), you should follow the high-level steps listed here. Note that you must upgrade from version 4.0.0 or later.

To upgrade a cluster:

  1. Stop all application server nodes in the cluster.
  2. Use the application package (such as the RPM on Linux) to set up a cache server on a separate machine. For more information, see Setting up cache server. Note the cache server address for use later in setting up application servers.
  3. Before proceeding, make sure the cache server you set up is running. It must be running while you set up application server nodes.
  4. On each node in the cluster, upgrade the application instance by using the package, but don't run the Setup wizard yet.

    For more information on upgrading the package, see Upgrading Jive package.

  5. Start one node and navigate to its instance with a web browser. Work through the upgrade tool, allowing it to run the upgrade tasks it lists.
  6. Restart the application server you've upgraded, then go to it with a web browser again.
  7. Enter the address of the cache server you installed, then complete the Setup wizard.
  8. After you've finished with the Setup wizard, restart the application server.
  9. Start the application server on each of the other nodes. Because it's connecting to the same database used by the server on the node you've already set up, the server on each subsequent node detects that clustering is enabled. Each also picks up the configuration you set on the first node.
  10. After setting up all of the application server nodes and running them once, restart all servers in the cluster to ensure that the address of each node in the cluster is known to all the other nodes. The entire cluster must be bounced after all the nodes are set up.
