Actually, I also reached around and found the same answer that the store-forward makes sure that a message exists in a single broker at a given point in time. The source of my original doubt was lack of explanation on how store forward works in the 'ActiveMQ in action' book, which I believe is an excellent reference.The link http://activemq.apache.org/how-do-distributed-queues-work.html explains the process pretty well. -- View this message in context: http://activemq.2283324.n4.nabble.com/Broker-Networks-and-duplicate-message-delivery-tp4201147p4211610.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
