Add vertical cluster members to a static cluster on AIX
Overview
Add vertical cluster members to share the workload demands of a cluster across multiple members running on the same physical machine.
Add a vertical cluster member
- Log onto the dmgr console and go to...
Servers | Clusters | WebSphere application server clusters | cluster_name | Cluster members | NewDefine the name of cluster member. Do not use spaces.
Select an existing node where WebSphere Portal is installed.
Check the box:
Generate Unique HTTP Ports
- 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, adding a new alias entry for the port number. Use "*" for host name.
- Click Finish, and save the changes.
The new cluster topology can be viewed from:
Servers | Clusters | Cluster TopologyTo list the new server cluster members:

- To enable cache replication, navigate to:
Servers | Server Types | WebSphere application servers | new vertical cluster member(s) | Container services | Dynamic cache serviceChange Cache size to 3000 entries.
- Check the box:
Enable cache replicationSelect NOT_SHARED from the Replication type drop-down menu.
- Save changes to the master configuration.
Click OK | Save
- To clean up the server-scoped resources, caches, and resource providers, on each vertical cluster member run:
cd WP_PROFILE/ConfigEngine
./ConfigEngine.sh cluster-node-config-vertical-cluster-setup -DServerName=vertical_cluster_servername -DWasPassword=foo.and restart the vertical cluster member referenced in the cluster-node-config-vertical-cluster-setup task.
- Save to master repository
- Resynchronize the nodes:
System Administration | Nodes | node | Full Resynchronize
- Regenerate the web server plug-in (plugin-cfg.xml)
- For remote web servers, copy the updated plug-in configuration file to the web server's plug-in configuration directory.
- Restart the web server.
