<h1>ActiveMQ Artemis Clustering with JGroups Example</h1>
|
|
|
|
<pre>To run the example, simply type <b>mvn verify</b> from this directory, <br>or <b>mvn -PnoServer verify</b> if you want to start and create the server manually.</pre>
|
|
|
|
<p>This example demonstrates the working of a two node cluster using JGroups as the underlying topology broadcasting/discovery
|
|
technique.</p>
|
|
<p>We deploy a queue on to the cluster, then create a consumer on the queue on each node, and we create a producer on only one of the nodes.</p>
|
|
<p>We then send some messages via the producer, and we verify that <b>both</b> consumers receive the sent messages
|
|
in a round-robin fashion.</p>
|
|
<p>This example uses JNDI to lookup the JMS Queue and ConnectionFactory objects. If you prefer not to use
|
|
JNDI, these could be instantiated directly.</p>
|
|
<p>To enable ActiveMQ Artemis to use JGroups you need to configure JGroups configuration file and make sure it is on the classpath
|
|
by placing in the configuration directory, the file test-jgroups-file_ping.xml is the configuration used in this
|
|
exaample</p>
|
|
<p>You then configure the jgroups file used by the broadcast and discovery groups in the configuration along with the
|
|
channel name which you want this cluster to share.</p>
