Multiple OpenSSO Enterprise Server Load Balancers in a Single Site, No Session Failover

The following figure illustrates a deployment with multiple OpenSSO Enterprise server load balancers in front of redundant OpenSSO Enterprise servers. In this example, both OpenSSO Enterprise server load balancers are specified in each Policy Agent bootstrap configuration. The load balancers are also configured as login URL's in each Policy Agent configuration. Policy Agent configuration can reside on the same host as the Policy Agent, or can reside in the OpenSSO Enterprise embedded configuration data store. Regardless of where the configuration is hosted, when one OpenSSO Enterprise server load balancer is inaccessible, all requests are automatically routed to the other load balancer.

The following figure illustrates the session handling part of the process flow. See Figure 17–2 for a detailed illustration of steps 1 through 13.
