Single OpenSSO Enterprise Server Load Balancer in Single Site, No Session Failover

This is the most basic high-availability configuration. The single OpenSSO Enterprise server load balancer increases transaction throughput. When one OpenSSO Enterprise server is inaccessible, requests are automatically routed to other servers. However, the single load balancer can be a single point of failure. When this load balancer is inaccessible, no OpenSSO Enterprise services or session data are available to the Policy Agents.
