Configure Apache Load Balancer

Make the changes in the workers.properties and uriworkermap.properties files to configure Apache load balancer to increase the number of agents in a cluster setup for secure and non-secure communication.

• workers.properties
  • Add "uiloadbalancer" in the list of workers that are used for mapping requests as follows:

    worker.list=uiloadbalancer, loadbalancer, status

  • Add the following entries to define load balancing behaviour for UI calls:

    worker.uiloadbalancer.type=lb

    worker.uiloadbalancer.balance_workers=node1

    worker.uiloadbalancer.sticky_session=1

    worker.uiloadbalancer.retries=1

  • Change the value of the following entry to "0":

    worker.loadbalancer.sticky_session=0

• uriworkermap.properties

  Change the value of the following entries to "uiloadbalancer"

  • /jmx-console
  • /jmx-console/*
  • /web-console
