Add vertical cluster members to a dynamic 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. To allow vertical clusters on your dynamic cluster:

    1. Navigate to Servers > Dynamic clusters and select the appropriate dynamic cluster.

    2. Select the Allow more than one instance to start on the same node check box under Vertical stacking of instances on node.

    3. Enter a new value in the Number of instances text box to determine the number of vertical cluster members allowed on each node.

    4. Click Apply and then click Save to save the changes to the master configuration.

    • 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.

    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.

  3. 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.

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

    1. Run...

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

      ...from...

        profile_root/ConfigEngine

      ...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.

  5. Access the Web Content Management content through an external Web server:

    1. Log on to the deployment manager administrative console.

    2. Select Environment > WebSphere Variables.

    3. From the Scope drop-down menu, select the Node=nodename, Server=servername option to narrow the scope of the listed variables, where Node=nodename is the node that contains the appserver.

    4. Update the WCM_HOST variable with the fully qualified host name used to access the WebSphere Portal server through the Web server or On Demand Router.

    5. Update the WCM_PORT variable with the port number used to access the WebSphere Portal server through the Web server or On Demand Router.

    6. To synchronize the node with the deployment manager:

      1. Select System Administration > Nodes.

      2. Select the node that you want to synchronize from the list.

      3. Click Full Resynchronize.

    7. Log off of the deployment manager administrative console.

  6. 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.

  7. Stop and start the Web server.
