About Siebel Connection Broker (SCBroker)
The Siebel Connection Broker (alias SCBroker) is a background-mode server component that provides intraserver load balancing. By default, it is always enabled and online. At least one instance of SCBroker must be running on the Siebel Server hosting interactive components.
NOTE: If a Siebel Server hosts only batch-mode components, SCBroker can be disabled to prevent it from listening on a TCP port.
SCBroker listens on a configurable, static port for new connection requests from the Web server or a third-party load balancer. The parameter, Static Port Number (alias PortNumber), defines the port that SCBroker monitors. The default value for this parameter is 2321. After a request is received, SCBroker distributes it to the appropriate instance of an Application Object Manager (AOM) running on the Siebel Server.
