Cluster with vertical cluster members

After federating your WebSphere Commerce environment, you can configure vertical clustering. Clustering provides failover protection and provides workload balancing.

Cluster with vertical cluster members refers to the practice of defining cluster members of an application server on the same physical machine. Experience has shown that a single application server, which is implemented by a single JVM process, cannot always fully utilize the processor power and RAM of a large multiprocessor machine. Clustering with vertical cluster members provides a straightforward mechanism to create multiple JVM processes, that together can fully use all the processing power and memory available.

Before clustering a WebSphere Commerce instance, it strongly recommended that you backup the WebSphere Application Server administrative configuration. Backing up the administrative configuration will allow you to restore the original configuration if clustering fails during the clustering process.

To create a cluster with vertical cluster members:

  1. Complete the installation of a WebSphere Commerce node using the custom install option of the installation wizard. For instructions, refer to the WebSphere Commerce Installation Guide.

  2. Create a WebSphere Commerce instance. For instructions, refer to the WebSphere Commerce Installation Guide.

  3. Federate the WebSphere Commerce node into a deployment manager cell.

  4. Create a WebSphere Commerce Cluster.

  5. Add additional cluster members.

  6. Regenerate the Web server plug-in and copy the plug-in to the Web server:

  7. Start the WebSphere Commerce cluster.
