Adding vertical cluster members

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

Before you begin

  1. Complete the installation of a WebSphere Commerce node by using the custom installation option of the installation wizard.
  2. Create a WebSphere Commerce instance.
  3. Before you cluster, it strongly recommended that you back up the WebSphere Application Server administrative configuration. If clustering fails during the clustering process, you can restore the backup. For more information, see Backing up and recovering the application server environment.
  4. Federate the WebSphere Commerce node into a deployment manager cell.
  5. Create a WebSphere Commerce Cluster.

About this task

Clustering with vertical cluster members refers to the practice of defining cluster members of an application server on the same physical machine. Tests show that a single application server, which is implemented by a single JVM process, cannot always fully use 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.
