Connection Failover

To specify whether the GlassFish Server tries to reconnect to the primary broker if the connection is lost, set the reconnect-enabled attribute in the JMS service. To specify the number of retries and the time between retries, set the reconnect-attempts and reconnect-interval-in-seconds attributes, respectively.

If reconnection is enabled and the primary broker goes down, the GlassFish Server tries to reconnect to another broker in the AddressList. The AddressList is updated whenever a JMS host configuration changes. The logic for scanning is decided by two JMS service attributes, addresslist-behavior and addresslist-iterations.

You can override these settings using JMS connection factory settings. For details, see Chapter 19, Administering the Java Message Service (JMS) , in Oracle GlassFish Server 3.0.1 Administration Guide.

The Message Queue software transparently transfers the load to another broker when the failover occurs. JMS semantics are maintained during failover.
