Connection Pooling and Failover

Enterprise Server supports JMS connection pooling and failover. The Enterprise Server pools JMS connections automatically. By default, Enterprise Server selects its primary MQ broker randomly from the specified host list. When failover occurs, MQ transparently transfers the load to another broker and maintains JMS semantics.
