Hi,
We run activemq web console + broker as a war app in tomcat, with "-Xms2048m
-Xmx8192m -XX:MaxPermSize=3072m -Xss256k".
We did follow JDBC persistence tutorial, and we use :
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>/etc/myfolder/activemq-persistence.properties</value>
</property>
</bean>
<bean id="storeDataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName"
value="${broker.store.jdbc.driverClass}"/>
<property name="url"
value="${broker.store.jdbc.url}?relaxAutoCommit=true"/>
<property name="username" value="${broker.store.jdbc.user}"/>
<property name="password" value="${broker.store.jdbc.password}"/>
<property name="poolPreparedStatements" value="true"/>
</bean>
<broker brokerName="web-console" useJmx="true"
xmlns="http://activemq.apache.org/schema/core"; persistent="true"
deleteAllMessagesOnStartup="false" schedulerSupport="false"
advisorySupport="true">
<persistenceAdapter>
<jdbcPersistenceAdapter dataSource="#storeDataSource" />
</persistenceAdapter>
<systemUsage>
<systemUsage>
<memoryUsage>
<memoryUsage limit="0"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="0"/>
</storeUsage>
<tempUsage>
<tempUsage limit="256mb"/>
</tempUsage>
</systemUsage>
</systemUsage>
And we regularly obtain :
