Torsten, I just tried the configuration you suggested. I made my consumer Network Connectors duplex and I still don't see any messages making it to the consumers.
If I connect with JMX to the stand alone broker I can see under org.apache.activemq.broker.Connection.openwire my 3 producers connected, I can identify the IP addresses of the servers. Under org.apache.activemq.broker.NetworkBridge I see my two duplex clients, I see in the connection attributes CreatedByDuplex=true. I also see under org.apache.activemq.brokerQueue.<name-of-my-queue>.Attributes.Subscriptions my consumers as subscribers. I implemented listeners for the queue advisories on the embedded brokers. After I place a new message on the producer side I see the size of the queue growing on the producer embedded broker but I don't see dequeueCount or inflightCount ever changing from 0, only size changes. On the stand alone broker queue stats I don't see EnqueueCount, DispatchCount, InFlightCount or QueueSize ever changing from 0 either. I also see on the stand alone broker's log messages like this one, one per duplex consumer: 2012-08-20 21:40:03,574 | INFO | Started responder end of duplex bridge connection_to_nob-10.17.163.168-8080@ID:mc02-48630-1345498803060-0:1 | org.apache.activemq.broker.TransportConnection | ActiveMQ Transport: tcp:///10.17.163.168:56989 2012-08-20 21:40:03,576 | INFO | Network connection between vm://broker#2 and tcp:///10.17.163.168:56989(localhost) has been established. | org.apache.activemq.network.DemandForwardingBridgeSupport | StartLocalBridge: localBroker=vm://broker#2 Do you guys have any other ideas? Would it be handy to submit configuration files or log files on a specific log level to help solve this issue? It's very strange that if I test the topology you suggested to test first, to have only embedded brokers on the producer side but the consumers connected directly messages actually flow. But if they both have embedded brokers messages just don't flow to the consumers. -- View this message in context: http://activemq.2283324.n4.nabble.com/Store-and-Forward-with-embedded-brokers-stand-alone-broker-tp4655028p4655340.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
