Add vertical cluster members to a static cluster

1. Log on to the dmgr console and go to...
   Servers | Clusters | WebSphere application server clusters | cluster_name | Cluster members | New

   1. Define the name of cluster member.

      Do not use spaces in the cluster member name.

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

   3. Check the box...
      Generate Unique HTTP Ports

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

2. Click Finish and save the changes.

   • View the new cluster topology from...
     Servers | Clusters | Cluster Topology

   • To list the new server cluster members...
     Servers | Server Types | WebSphere application servers

3. Update the virtual host entries for the new port created when adding a cluster member.

   Update the default_host virtual host, then add an alias entry for the port number. Use an "*" wildcard character for the host name.

4. To enable cache replication:

   1. From the dmgr console, go to...
      Servers | Server Types | WebSphere application servers | vertical_cluster_member | Container services | Dynamic cache service

   2. Change Cache size to 3000 entries.

   3. Check the Enable cache replication check box.

   4. Select NOT_SHARED from the Replication type menu.

   5. Click OK.

   6. Click Save to save the changes to the master configuration.

5. To clean up the server-scoped resources, caches, and resource providers:
   cd WP_PROFILE/ConfigEngine
   ./ConfigEngine.sh cluster-node-config-vertical-cluster-setup -DServerName=vertical_cluster_member -DWasPassword=foo

6. Restart the vertical cluster member

7. Save the changes and resynchronize the nodes.

   1. In the dmgr console, click Save on the task bar.

   2. Save the administrative configuration.

   3. Select...
      System Administration | Nodes | node | Full Resynchronize

8. If we transferred the databases after creating the cluster, complete the following steps on each vertical cluster member:

   1. Log on to the dmgr console and go to...
      Environment | WebSphere Variables | Scope menu Node=nodename, Server=servername

   2. Update the WCM_DATASOURCE variable with the JCR data source name.

      For example...

      jdbc/wpdbds_jcr

   3. Save all changes and synchronize the nodes.

9. Regenerate the web server plug-in.

   1. Log in to the dmgr console.

   2. Copy the updated plug-in configuration file (plugin-cfg.xml) to the web server's plug-in configuration directory.

   3. Stop and start the web server.
