Info

If the bus member is a cluster of application servers, a queue point is created and associated with each messaging engine defined within the bus member. The queue destination is partitioned across the available messaging engines within the cluster. In this configuration, message ordering is not maintained on the queue destination. ► Publication points A publication point is the message point for a topic space. When creating a topic space destination, an administrator does not need to specify a bus member to hold messages for the topic space. Creating a topic space destination automatically defines a publication point on each messaging engine within the bus. Foreign bus and link A foreign bus is an external messaging product that is either another SIBus or a WebSphere MQ network. You can set up a link to it so that messages traverse from one bus to another. The WebSphere MQ network can be seen as a foreign bus by the WebSphere Application Server default messaging provider using a WebSphere MQ link. JMS and the default messaging provider Java Enterprise Edition (Java EE) applications (producers and consumers) access the SIBus and the bus members through the JMS API. JMS destinations are associated with SIBus destinations. A SIBus destination implements a JMS destination function. Session Enterprise JavaBeans (EJBs) use a JMS connection factory to connect to the JMS provider. Message Driven Beans (MDBs) use a JMS activation specification to connect to the JMS provider.
