The Operation Console cluster typically consists of the following components:

Browser clients.
B2B Data Exchange
users log in to the browsers and perform actions in the Operation Console.
Load balancer. Receives requests from each Operation Console browser and forwards the requests to the available Tomcat server instance.
Tomcat Operation Console server. Receives and processes forwarded requests from the load balancer.

The following figure shows an example of the Operation Console cluster configuration:

This cluster consists of three browser clients, one load balancer, and two Tomcat instances that run the Operation Console and the Dashboard. The communication lines between the components represent actions that users perform in the Operation Console that the load balancer distributes between the Tomcat instances. Synchronize the clocks of all machines in the cluster to within 30 seconds of each other to ensure proper handling of browser requests.
