The following are the requirements to implement Tomcat load balancing:
  • A properly configured web server.

    If you run one or more web application available to the public, then install the Tomcat web server in a DMZ with the PAS for OpenEdge instances running behind a second firewall.

  • A PAS for OpenEdge instance that is dedicated to load balancing.

    Do not deploy any web applications to the load balancer.

  • A workers.properties file.

    The workers.properties file specifies the existence of a load balancer, the workers (instances) that are available to the load balancer as servers that can handle requests, and an optional status worker that monitors the run-time status of the other workers.

    You can create a workers.properties file with the TCMAN workers action.
