Cluster with horizontal cluster members

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

Cluster with horizontal cluster members refers to the traditional practice of defining cluster members of an application server on multiple physical machines, allowing a single application to span several machines while presenting a single system image. Clustering with horizontal cluster members can provide increased throughput and high availability.

Before clustering a WebSphere Commerce instance, it strongly recommended that you backup the WAS 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 horizontal cluster members:

  1. Complete the installation of a WebSphere Commerce node. 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. Prepare additional nodes for each node that you want to add to the cluster.

  5. Define the JDBC provider path for each node that contains a server that is or will be a member of the WebSphere Commerce cluster..

  6. Create a WebSphere Commerce Cluster.

  7. Add additional cluster members if required.

  8. Regenerate the Web server plug-in and copy the plug-in to the Web server.

  9. Start your WebSphere Commerce cluster.
