Adding vertical cluster members to a static cluster | HCL Digital Experience
You can add vertical cluster members to share the workload demands of your cluster across multiple members on the same physical server.
Procedure
- Log on to the deployment manager WebSphere® Integrated Solutions Console.
- Go to .
- Click New to create the cluster
member.
Important: Update the virtual host entries for the new port that is created when you added a cluster member. Update the default_host virtual host in the WebSphere® Integrated Solutions Console. Then, add an alias entry for the port number. Use an "
*
" wildcard character for the host name. Read Configuring virtual hosts for information. - Click Finish and save the changes.
- View the new cluster topology from .
- The view lists the new server cluster members.
- Complete the following steps to enable cache replication:
- From the deployment manager WebSphere® Integrated Solutions Console, go to .
- Click the new vertical cluster member.
- Click Dynamic cache service under Container services.
- Change Cache size to 3000 entries.
- Check the Enable cache replication check box.
- Select NOT_SHARED from the Replication type menu.
- Click OK.
- Click Save to save your changes to the master configuration.
- Open a command prompt.
- Change to the wp_profile_root/ConfigEngine directory.
-
Run the following command on each vertical cluster member to clean up the server-scoped
resources, caches, and resource providers:
- AIX® Linux™: ./ConfigEngine.sh cluster-node-config-vertical-cluster-setup -DServerName=unique vertical cluster servername -DWasPassword=password
- Windows™: ConfigEngine.bat cluster-node-config-vertical-cluster-setup -DServerName=unique vertical cluster servername -DWasPassword=password
The unique vertical cluster servername is the name that you specified when you created the cluster member. -
The binary cache that is used by the JCR cannot share files between Portal JVMs. Therefore,
each cluster member that is on a single host system must have its own directory that is specified
for the JCR binary file cache property. Complete the following steps to configure the
directories:
- Restart the vertical cluster member that is referenced in the cluster-node-config-vertical-cluster-setup task.
- Save your changes and resynchronize the nodes.
- In the deployment manager WebSphere® Integrated Solutions Console, click Save on the taskbar.
- Save your administrative configuration.
- Go to .
- Select the node from the list.
- Click Full Resynchronize.
- If you transferred your databases after you created the
cluster, complete the following steps on each vertical cluster member:
- Regenerate the web server plug-in.
- Log in to the deployment manager WebSphere® Integrated Solutions Console.
-
Copy the updated plug-in configuration file (
plugin-cfg.xml
) to the web server's plug-in configuration directory. - Stop and start the web server.
