Configure Apache Load Balancer for Agent Scalability

You can configure the Apache load balancer to increase the number of agents in a cluster setup for secure and non-secure communication.

Follow these steps:

1. Make the following changes in the workers.properties file:
   • 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

2. Change the value of the following entries to "uiloadbalancer" in the uriworkermap.properties file:
   • /jmx-console
   • /jmx-console/*
   • /web-console
   • /web-console/*
   • /itpam/*
   • /itpam
   • /c2orepository/oasisHelp
   • /c2orepository/oasisHelp/*
   • /c2orepository/htmlFile/aboutUs/*
   • /c2orepository/htmlFile/language/*
   • /itpam/OasisPrimary
   • /itpam/JNLPRequestProcessor/installation
   • /itpam/clientproxy/c2oresourceaction
   • /itpam/clientproxy/c2oreportaction

Note: A new installation of CA Process Automation does not require any manual changes in the workers.properties and uriworkermap.properties files. For more information, see Install a Load Balancer and Prepare Configuration Templates (Windows).
