I'm seeing the exact same behavior when using a javax.jms.MessageConsumer.
Whenever I'm powering off or unplugging the master broker machine,The slave
broker will take over the master role but the consumers will not reconnect to
the new master broker.
There are no logged errors or other type of messages on the consumer side. The
consumer behaves like it is still connected to the previous master instance and
it is waiting for the messages to arrive in the queue.
I was thinking of implementing a thread on my consumer side which will query
the JMS connection from time to time, hopefully this way the fail-over
mechanism will kick in. Although I'm not convinced that this is the right
approach.
The broker URL I'm using is:
failover:(tcp://server1:61616?keepAlive=true&wireFormat.maxInactivityDuration=0,tcp://server2:61616?keepAlive=true&wireFormat.maxInactivityDuration=0)?randomize=false&updateURIsSupported=false&jms.prefetchPolicy.all=1
The ActiveMQ version I'm using is 5.8.0
The client side libraries were 5.4.2, 5.7.0 and 5.8.0

> I've set up a durable topic with the default (persistent) delivery mode on
> one machine that is publishing a simple text message every 5 seconds. I
> created a durable subscriber that consumes messages published to the above
> topic on another machine. I am using broker to broker communication between
> the two machines.
> I start up the two programs on either machine and see the messages coming
> through to the subscriber. If I then pull the network cable to disconnect the
> network between the two machines, wait for a minute and then plug it back in,
> my subscriber doesn't receive the messages any more. I can see from the
> output that the publisher is still publishing them (Temporary topics,
> non-durable queues all continue to sync up in our production environment, it
> is only the durable topics that don't work after network reconnect)
> If I were to tweak a setting on the publisher's broker (that was introduced
> only in 5.5.0), suppressDuplicateTopicSubscriptions=false, then the topics
> work correctly after network reconnect. But this may have other unintended
> consequences and I was hoping to get a better idea of:
> - is this a known issue ? if so, then are there any specific challenges that
> have caused it not to be fixed?
> - are other people out there using durable topics and subscribers without a
> failover option that have run into this problem? What have they done to work
> around?
> Here is how my subscriber and publisher are set up:
> Topic Publisher (Machine 1)
> publisherConnection = connFactory.createConnection();
> publisherConnection.setClientID( "ProducerCliID" );
> publisherConnection.start();
> session = publisherConnection.createSession( true, -1 );
> Destination producerTopic = session.createTopic( TEST_TOPIC_NAME );
> producer = session.createProducer( (Topic)producerTopic );
> ....
> ....
> ....
> // On a timer, keep sending this out every 5 seconds
> String text = "HELLO " + count++;
> TextMessage msg = session.createTextMessage( text );
> System.out.println( "Sending TextMessage = " + msg.getText()
> );
> producer.send( msg );
> session.commit();
> Subscriber ( Machine 2):
> Connection clientConnection = connFactory.createConnection();
> clientConnection.setClientID("cliID");
> clientConnection.start();
> Session session = clientConnection.createSession( false,
> Session.AUTO_ACKNOWLEDGE );
> Destination topic = session.createTopic( topicName );
> MessageConsumer subscriber = session.createDurableSubscriber(
> (Topic)topic, "subName" );
> TestMessageListener msgListener = new TestMessageListener( 1000 );
> subscriber.setMessageListener( msgListener );
> .....
> .....
> // TestMessageListener's onMessage method simply outputs the message:
> public void onMessage(Message message)
> {
> if ( message instanceof TextMessage )
> {
> System.out.println( "Message received = " +
> ((TextMessage)message) );
> }
> }
> I can provide the jars for you to run the program if need be.
