Campaign web application server clustering
You can deploy the Campaign web application server in a clustered environment to support load balancing.
Before you begin the installation, be sure to read HCL Campaign web application clustering.
Campaign listener server clustering
Listener (analytic) server clustering, also referred to as back-end clustering, involves the use of multiple listeners for the purpose of high availability and load balancing. Listener clustering is important because flowchart runs happen at the back end.
Before you begin the installation, be sure to read Installing a clustered listener environment.
