The Apache ActiveMQ team has just released the new ActiveMQ 5.9 release<\/a>.<\/p>\n

\"Apache<\/a>
Apache ActiveMQ 5.9 released<\/a><\/figcaption><\/figure><\/p>\n

This release is 8 months of hard work since the previous 5.8 release.<\/p>\n

In this release we have as usual more hardening of the broker, and the recent new protocols such as AMQP and MQTT. Also very interesting is the hardening of the leveldb persistent store<\/a>, which now also includes a new replication functionality<\/a>. Over time level db is planned to be default out of the box persistent store, instead of the current kahadb store<\/a>. Though we are not there yet, so kahadb is still the default store.<\/p>\n

Another great new functionality is the ability to do runtime configuration changes<\/a> to the broker without having to restart the broker. You cannot change everything yet, but you can for example update network connectors when you have clustered brokers etc. The documentation details which parts can be updated.<\/p>\n

For the Camel users then there is a new broker component<\/a> which allows lighter inter broker routing. Rob Davies have previously blogged about that, and provides an interesting use-case which allows to use Camel routing logic to decide if sending a message to a queue should go into the queue, or to another queue, depending on the current queue depth.<\/p>\n

Last but not least Apache ActiveMQ now ships with hawtio<\/a> as its new web console out of the box. The old web console is still there, but is considered deprecated.

<\/div> <\/div><\/p>\n

We also cleaned up in the conf directory, moving all the example configurations into examples\/conf.<\/p>\n

Apache ActiveMQ 5.9 release notes is here<\/a>.<\/p>\n

Starting Apache ActiveMQ<\/h2>\n

To try out Apache ActiveMQ is easy. You go to the activemq.apache.org web site and click the download link. Then you can download a zip or tgz file of the distribution. Then you unzip\/untar the file and then you can start the broker from the command line as shown below:<\/p>\n

davsclaus:\/opt$ tar xf ~\/Downloads\/apache-activemq-5.9.0-bin.tar.gz\r\ndavsclaus:\/opt$ cd apache-activemq-5.9.0\/\r\ndavsclaus:\/opt\/apache-activemq-5.9.0$ bin\/activemq console<\/pre>\n
When the broker is staring up it now logs all the transport connectors it provides and their urls.<\/p>\n
From the logs below we can see that …<\/p>\n
INFO | Listening for connections at: tcp:\/\/davsclaus.air:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600\r\n INFO | Connector openwire started\r\n INFO | Listening for connections at: amqp:\/\/davsclaus.air:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600\r\n INFO | Connector amqp started\r\n INFO | Listening for connections at: stomp:\/\/davsclaus.air:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600\r\n INFO | Connector stomp started\r\n INFO | Listening for connections at: mqtt:\/\/davsclaus.air:1883?maximumConnections=1000&wireFormat.maxFrameSize=104857600\r\n INFO | Connector mqtt started\r\n INFO | Listening for connections at ws:\/\/davsclaus.air:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600\r\n INFO | Connector ws started<\/pre>\n
