ActiveMQ - delete/purge all queue via command line

Question

Is there a way to delete / purge all queues in ActiveMQ via the command line (win/linux)? I could only find the commands for a specific queue. Or maybe there\'s a way to do this

Answer 1

1- go to amq bin folder, in my case:

cd /opt/amq/bin

2- run amq client:

./client

3- run purge on desired queue

activemq:purge <QUEUE NAME HERE>

Answer 2

I developed my own ActiveMQ command line utility (activemq-cli) to do this. You can find it here: https://github.com/antonwierenga/activemq-cli (command 'purge-all-queues' or 'remove-all-queues').

Answer 3

You can do tweak your activemq.xml a bit:

<broker deleteAllMessagesOnStartup="true"  ...>

This works with KahaDB message stores (it has problems with JDBC message stores), all your messages get deleted and subsequently queues are cleared.

As you want all queues to be deleted, restarting the broker won't be a costly option to clean everything up.

The purge will happen on 'every' restart

Another possibility is to deploy a small Camel route in a container (e.g. Apache ServiceMix) or simply by executing a java program which contain the route.

For example here is the route I currently use on my development computer where I also have the ServiceMix installed:

            </handled>
            <to uri="activemq:queue:CLEANUP_DLQ" />
        </onException>

        <route id="drop-all-queues" autoStartup="true">
            <from uri="activemq:queue:*.>" />
            <stop/>
        </route>
    </camelContext>

    <bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
        <property name="brokerURL" value="${amq.local.url}" />
    </bean>
</blueprint>

As of version 5.0 it looks like this can be done using the CLI provided with ActiveMQ itself:

$ ActiveMQ/bin/activemq purge
