In the Admin Console, you can set JMS properties using the Java Message Service node for a particular configuration. You can set properties such as Reconnect Interval and Reconnect Attempts. For more information, see Chapter 4, Configuring Java Message Service Resources, in Sun GlassFish Enterprise Server v2.1.1 Administration Guide.
The JMS Hosts node under the Java Message Service node contains a list of JMS hosts. You can add and remove hosts from the list. For each host, you can set the host name, port number, and the administration user name and password. By default, the JMS Hosts list contains one MQ broker, called “default_JMS_host,” that represents the local MQ broker integrated with the Enterprise Server.
Configure the JMS Hosts list to contain all the MQ brokers in the cluster. For example, to set up a cluster containing three MQ brokers, add a JMS host within the Java Message Service for each one. Message Queue clients use the configuration information in the Java Message Service to communicate with MQ broker.
