The &lt;broker&gt; element is used to configure the ActiveMQ broker.
--&gt;
&lt;broker xmlns=&quot;http://activemq.apache.org/schema/core&quot; brokerName=&quot;localhost&quot; dataDirectory=&quot;${activemq.data}&quot;&gt;
&lt;destinationPolicy&gt;
&lt;policyMap&gt;
&lt;policyEntries&gt;
&lt;policyEntry topic=&quot;&gt;&quot; &gt;
&lt;!-- The constantPendingMessageLimitStrategy is used to prevent
slow topic consumers to block producers and affect other consumers
by limiting the number of messages that are retained
For more information, see:
http://activemq.apache.org/slow-consumer-handling.html
--&gt;
&lt;pendingMessageLimitStrategy&gt;
&lt;constantPendingMessageLimitStrategy limit=&quot;1000&quot;/&gt;
&lt;/pendingMessageLimitStrategy&gt;
&lt;/policyEntry&gt;
&lt;/policyEntries&gt;
&lt;/policyMap&gt;
&lt;/destinationPolicy&gt;
&lt;!--
The managementContext is used to configure how ActiveMQ is exposed in
JMX. By default, ActiveMQ uses the MBean server that is started by
the JVM. For more information, see:
http://activemq.apache.org/jmx.html
--&gt;
&lt;managementContext&gt;
&lt;managementContext createConnector=&quot;false&quot;/&gt;
&lt;/managementContext&gt;
&lt;!--
Configure message persistence for the broker. The default persistence
mechanism is the KahaDB store (identified by the kahaDB tag).
For more information, see:
http://activemq.apache.org/persistence.html
--&gt;
&lt;persistenceAdapter&gt;
&lt;kahaDB directory=&quot;${activemq.data}/kahadb&quot;/&gt;
&lt;/persistenceAdapter&gt;
&lt;!--
The systemUsage controls the maximum amount of space the broker will
use before disabling caching and/or slowing down producers. For more information, see:
http://activemq.apache.org/producer-flow-control.html
--&gt;
&lt;systemUsage&gt;
&lt;systemUsage&gt;
&lt;memoryUsage&gt;
&lt;memoryUsage percentOfJvmHeap=&quot;70&quot; /&gt;
&lt;/memoryUsage&gt;
&lt;storeUsage&gt;
&lt;storeUsage limit=&quot;100 gb&quot;/&gt;
&lt;/storeUsage&gt;
&lt;tempUsage&gt;
&lt;tempUsage limit=&quot;50 gb&quot;/&gt;
&lt;/tempUsage&gt;
&lt;/systemUsage&gt;
&lt;/systemUsage&gt;
&lt;!--
The transport connectors expose ActiveMQ over a given protocol to
clients and other brokers. For more information, see:
http://activemq.apache.org/configuring-transports.html
--&gt;
&lt;transportConnectors&gt;
&lt;!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB --&gt;
&lt;transportConnector name=&quot;openwire&quot; uri=&quot;tcp://0.0.0.0:61616?maximumConnections=1000&amp;amp;wireFormat.maxFrameSize=104857600&quot;/&gt;

&lt;/transportConnectors&gt;
&lt;!-- destroy the spring context on shutdown to stop jetty --&gt;
&lt;shutdownHooks&gt;
&lt;bean xmlns=&quot;http://www.springframework.org/schema/beans&quot; class=&quot;org.apache.activemq.hooks.SpringContextHook&quot; /&gt;
&lt;/shutdownHooks&gt;
&lt;/broker&gt;
&lt;!--
Enable web consoles, REST and Ajax APIs and demos
The web consoles requires by default login, you can disable this in the jetty.xml file
Take a look at ${ACTIVEMQ_HOME}/conf/jetty.xml for more details
--&gt;
&lt;import resource=&quot;jetty.xml&quot;/&gt;
&lt;/beans&gt;
