Add vertical cluster members to a static cluster

You can add vertical cluster members to share the workload demands of the cluster across multiple members running on the same physical machine. Add a vertical cluster member to the clustered environment:

  1. Open a browser and enter http://DM01:9060/ibm/console in the address bar to access the administrative console on the deployment manager, where DM01 is the deployment manager node or host name.

    The port number might differ based on your installation.

  2. Depending on your version of WAS, make the appropriate selection from the navigation:

    • For WAS v6.1:

      Click Servers > Clusters in the console navigation tree, select the cluster name, and then click Cluster members from the list of additional properties.

    • For WAS v7:

      Click Servers > Clusters > WebSphere appserver clusters > cluster_name > Cluster members.

  3. Click New to create the cluster member.

    1. Define the name of cluster member.

      Do not use spaces in the cluster member name.

    2. Select an existing node where WebSphere Portal is installed.

    3. Check the box Generate Unique HTTP Ports.

    4. Click Add Member and then click Next to view the summary.

    Update the virtual host entries for the new port created when adding a cluster member. You can do this by updating the default_host virtual host in the administrative console and adding a new alias entry for the port number (use an "*" wildcard character for the host name). See Configure virtual hosts.

  4. Click Finish, and save the changes.

    • The new cluster topology can be viewed from the Servers > Cluster Topology view. If using WAS v7.0, the new cluster topology can be viewed from the Servers > Clusters > Cluster Topology view.

    • The Servers > Application Servers view will list the new server cluster members.

      If using WAS v7.0, the Servers > Server Types > WebSphere appservers view will list the new server cluster members.

  5. To enable cache replication:

    1. From the deployment manager Administrative Console, navigate to Servers > Application servers and then click the new vertical cluster member(s). If using WAS v7.0, navigate to Servers > Server Types > WebSphere appservers and then click the new vertical cluster member(s).

    2. Click Dynamic cache service under Container services.

    3. Change Cache size to 3000 entries.

    4. Check the Enable cache replication check box.

    5. Select Push only from the Replication type drop-down menu.

    6. Click OK.

    7. Click Save to save your changes to the master configuration.

  6. Perform the following steps on each vertical cluster member to clean up the server-scoped resources, caches, and resource providers:

    1. Run...

        ./ cluster-node-config-vertical-cluster-setup -DServerName=unique vertical cluster servername -DWasPassword=password



      ...where unique vertical cluster servername is generated by the Deployment Manager when the vertical cluster member is created.

    2. Restart the vertical cluster member referenced in the cluster-node-config-vertical-cluster-setup task.

  7. Save changes and resynchronize the nodes.

    1. In the administrative console for the deployment manager, click Save on the task bar, and save your administrative configuration.

    2. Select System Administration > Nodes, select the node from the list, and click Full Resynchronize.

  8. Regenerate the Web server plug-in.

    1. Regenerate the Web server plug-in using the deployment manager administrative console.

    2. For a remote Web server, copy the updated plug-in configuration file (plugin-cfg.xml) to the Web server's plug-in configuration directory.

  9. Stop and start the Web server.
