Read: TIBCO Administrator Fault tolerence

"TIBCO Administrator offers fault tolerance capabilities by allowing a client application to be served by multiple servers. Fault tolerance is implemented through the use of the TIBCO Rendezvous distributed queue protocol (RVDQ). Each logical server has a distributed queue based on the server name. The servers in a distributed queue group share the same server name. The TIBCO Administrator client just sees one logical server."
