Add vertical cluster members to a static cluster on AIX

We 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. Log into the dmgr console.

2. 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 IBM 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. We can do this by updating the default_host virtual host in the WAS admin console and adding a new alias entry for the port number (use an "*" wildcard character for the host name). See Configure virtual hosts for information.

4. Click Finish, and save the changes.

   • The new cluster topology can be viewed from the Servers > Clusters > Cluster Topology view.

   • The Servers > Server Types > WebSphere appservers view lists the new server cluster members.

5. To enable cache replication:

   1. From the dmgr console, go 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 NOT_SHARED from the Replication type drop-down menu.

   6. Click OK.

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

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

   1. On the node where createdd the vertical cluster...
      ./ConfigEngine.sh cluster-node-config-vertical-cluster-setup -DServerName=unique vertical cluster servername -DWasPassword=foo

      unique vertical cluster servername is the name you specified when createdd the cluster member.

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

7. Save the changes and resynchronize the nodes.

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

   2. If we are using 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.
