+          <p>Durable queues keep messages around persistently for any suitable consumer to consume them. Durable queues do not need to concern themselves with which consumer is going to consume the messages at some point in the future. There is just one copy of a message that any consumer in the future can consume.</p>
+
+<p>Durable topics however are different as they must logically persist an instance of each suitable message for every durable consumer - since each durable consumer gets their own copy of the message.</p>
+
+<p>For example imagine a durable subscriber S starts up subscribing to topic T at time D1. Some publisher sends messages M1, M2, M3 to the topic and S will receive each of these messages. Then S is stopped and the publisher continues to send M4, M5.</p>
+
+<p>When S restarts at D2, the publisher sends M6 and M7. Now S will receive M4, M5 followed by M6 and M7 and all future messages. i.e. S will receive all messages from M1..M7.</p>
+
+<p>This is the difference between durable and non-durable publishing. If S were a non-durable pubisher then it would only have received M1, M2, M3 and M6, M7 - not M4 and M5. i.e. because the subscription is durable, S will receive every message sent to T whether the subscriber is running or not. For non-durable topics, only messages delivered to the topic T when S is running are delivered.</p>
+
+<p>So for durable topic subscription, the JMS provider needs to be able to identify S when it shuts down and later on in the future reconnects, so it can know what messages to send to it while it was not running. JMS specification dictates that the identification of S is done by a combination of the clientID and the durable subscriber name. This is so that the JMS connection S uses can have many different durable subscriptions on different topics or on the same topic with different selectors - yet the JMS provider can know which message for which subscription to keep around for it.</p>
+
+<p>So setting the clientID on a JMS connection is vital (along with using a sensible durable consumer name) for durable topic subscription. Its not an issue for other <a href="/QoS" title="QoS">QoS</a></p>

+
+<p>There are 2 kinds of transaction support in ActiveMQ. </p>
+
+<ul>
+	<li>JMS transactions - the commit() / rollback() methods on a Session  (which is like doing commit() / rollback() on a JDBC connection)</li>
+	<li>XA Transactions - where the <span class="nobr"><a href="http://activemq.codehaus.org/maven/apidocs/org/activemq/ActiveMQXASession.html">XASession</a></span> acts as an <span class="nobr"><a href="http://java.sun.com/j2ee/1.4/docs/api/javax/transaction/xa/XAResource.html">XAResource</a></span> by commmunicating with the Message Broker, rather like a JDBC Connection takes place in an XA transaction by communicating with the database.</li>
+</ul>
+
+
+<p>They are both implemented fairly similarly. When operations are carried out on a transacted (or XA transacted) session, a transaction command is sent to the broker, with a unique transaction ID which is then followed by all the usual commands (send message, acknowledge message etc). </p>
+
+<p>Then when a commit() or rollback() is called on the Session, this command is sent to the broker for it to commit or rollback the transaction.</p>
+
+<p>Now the operations carried out on a transacted session inside a transaction, like a send message or acknowledge message, do not really perform a real send or acknowledge until the commit occurs. So the Broker explicitly handles these cases separately - essentially buffering up the commands until the commit occurs when the messages are really sent or acknowledged.</p>
+
+<p>If you wanna see the code, take a look at the methods</p>
+
+<ul>
+	<li><span class="nobr"><a href="http://activemq.codehaus.org/maven/apidocs/org/activemq/broker/Broker.html#acknowledgeTransactedMessage(org.activemq.broker.BrokerClient,%20java.lang.String,%20org.activemq.message.MessageAck)">acknowledgeTransactedMessage</a></span></li>
+	<li><span class="nobr"><a href="http://activemq.codehaus.org/maven/apidocs/org/activemq/broker/Broker.html#sendTransactedMessage(org.activemq.broker.BrokerClient,%20java.lang.String,%20org.activemq.message.ActiveMQMessage)">sendTransactedMessage</a></span></li>
+</ul>
+
+
+<p>Which differ from the normal operations</p>
+
+<ul>
+	<li><span class="nobr"><a href="http://activemq.codehaus.org/maven/apidocs/org/activemq/broker/Broker.html#acknowledgeMessage(org.activemq.broker.BrokerClient,%20org.activemq.message.MessageAck)">acknowledgeMessage</a></span></li>
+	<li><span class="nobr"><a href="http://activemq.codehaus.org/maven/apidocs/org/activemq/broker/Broker.html#sendMessage(org.activemq.broker.BrokerClient,%20org.activemq.message.ActiveMQMessage)">sendMessage</a></span></li>
+</ul>
+
+
+<p>The only real difference with XA transactions is that at the PREPARE stage we MUST write every command we have received (the send message or acknowledge message commands) to a persistent store so that we can recover properly.</p>
+
+<p>For this we write the commands to the <span class="nobr"><a href="http://activemq.codehaus.org/maven/apidocs/org/activemq/store/PreparedTransactionStore.html">PreparedTransactionStore</a></span></p>

+          <p>There are some similarities between the two; they both support JMS 1.1 and run inside <a href="/JBoss+Integration" title="JBoss Integration">JBoss 4.x</a>.</p>
+
+<p>However ActiveMQ does offer some specific differences and advantages (at least from our perspective)</p>
+
+<ul>
+	<li>ActiveMQ works great in any JVM not just inside the JBoss application server</li>
+	<li>ActiveMQ supports distributed destinations across networks</li>
+	<li>ActiveMQ supports reliable connections with <a href="/Configuring+Transports" title="Configuring Transports">configurable</a> automatic reconnection</li>
+	<li>ActiveMQ has great <a href="/Spring+Support" title="Spring Support">Spring Support</a></li>

+	<li>ActiveMQ is very fast; often 10x faster than JBossMQ.</li>
+</ul>
+

+<p>We have a performance report comparing ActiveMQ against a number of other commercial and open source JMS providers. You can get the report <span class="nobr"><a href="http://logicblaze.com/product_information.jsp">here</a></span> alternatively if you'd like a copy of our performance report comparing ourselves against various other open source and commercial JMS providers please send an email to <b>dev at logicblaze.com</b>.</p>
