Patent ID: 8898271

Claim:
A system for supporting load balancing in a transactional middleware machine environment with a plurality of transactional middleware machines, comprising: a plurality of service response time tables, wherein each transactional middleware machine in the transactional middleware machine environment includes at least one transactional server and a service response time table, wherein each said service response time table includes service response times for each said transactional server deployed in the transactional middleware machine environment; wherein each said service response time table is usable by a client on the associated transactional middleware machine to make routing decisions for a service request; and a plurality of synchronization servers, wherein each said synchronization server is associated with a transactional middleware machine in the transactional middleware machine environment; wherein the plurality of synchronization servers operates to periodically synchronize the transactional server response times included in the plurality of service response time tables in the transactional middleware machine environment.
