Dynamic Destinations
Dynamic destinations are created on-the-fly by the EMS server, as required by client applications. Dynamic destinations do not appear in the configuration files and exist as long as there are messages or consumers on the destination. A client cannot use JNDI to lookup dynamic queues and topics.
When you use the show queues or show topics command in the administration tool, you see dynamic topics and queues have an asterisk (*) in front of their name in the list of topics or queues. If a property of a queue or topic has an asterisk (*) character in front of its name, it means that the property was inherited from the parent queue or topic and cannot be changed.
See Dynamically Create Topics and Queues for details on topics and queues can be dynamically created by the EMS server.
