Set Up a Load Balancer for Orchestrator Clustering › F5 Load Balancer Prerequisites › Create an F5 iRule for CA Process Automation › The iRule Definition

The iRule Definition

Type the following definition in the Definition text box for your new iRule. Tailor the values for the set statements as needed.

• Set the PAMPOOL variable to values specific to the current pool with port as 8080 for basic (unsecure) communication.
• Set the IP addresses for NODE1 and NODE2 to values of the servers in the PAMWSPOOL pool.
• Use set WSPORT "80" for HTTP or set WSPORT "443" to use the secure (HTTPS) port for simplified communication.

  Important! For the 11.3.0, 11.2.1, 11.2.0, 11.1.0, 11.0.0 versions of F5 load balancer with simplified communications mode enabled for the agents, follow these steps:

  1. Add the following line in the when HTTP_REQUEST block:

     if { [string tolower [HTTP::header Upgrade]] contains "websocket" }{
        	   HTTP::disable
     }
     

  2. Restart the agents.
