Sun Cluster HA for Siebel provides Fault Monitoring and automatic failover for the Siebel application. High availability is provided for the Siebel gateway and Siebel server. With a Siebel implementation, any physical node running the Sun Cluster agent cannot be running the Resonate agent as well. Resonate and Sun Cluster can co-exist within the same Siebel enterprise, but not on the same physical server.
