Message consumers
Message consumers can be classified as durable and non-durable
subscribers and synchronous and asynchronous message consumers.
Sub-topics
Durable subscribers
A durable subscriber is a message consumer that receives
all messages published on a topic, including those published while
the subscriber is inactive.
Non-durable subscribers
A non-durable subscriber is a message consumer that only
receives messages that are published while the subscriber is active.
Messages delivered while the subscriber is inactive are lost.
Asynchronous message consumers
The asynchronous message consumer receives message from
a queue asynchronously. The message listener registered by the application
is invoked whenever a new message is available on the queue.
Poison messages
A poison message is one which cannot be processed by a
receiving MDB application. If a poison message is encountered, the
XMS MessageConsumer object can requeue it according to two queue properties,
BOQUEUE, and BOTHRESH.
