The <broker> element is used to configure the ActiveMQ broker.
Configuring the use of JMX
-
<broker xmlns= "Http://activemq.apache.org/schema/core" brokername= "broker" datadirectory= "${activemq.data}" Usejmx= "true" >


<destinationPolicy>
<policyMap>
<policyEntries>
<policyentry topic= ">" >
<!--the constantpendingmessagelimitstrategy is used to prevent
Slow topic consumers to block producers and affect other consumers
By limiting the number of messages that is retained
For more information, see:

<!--
The managementcontext is used to configure how ActiveMQ are exposed in
Jmx. By default, ActiveMQ uses the MBean server, which is started by
The JVM. For more information, see:


Http://activemq.apache.org/jmx.html
Configure Port connectorport=1099
-
<managementContext>
<managementcontext connectorport= "1099" createconnector= "true"/>

<!--
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
-
<persistenceAdapter>
&LT;KAHADB directory= "${activemq.data}/kahadb"/>

<!--
The Systemusage controls the maximum amount of space the broker would
Use before disabling caching and/or slowing down producers. For more information, see:
