I am running active MQ in master / slave mode against mySQL datastore.The two
brokers instances are broker-1 and broker -2 . The goal is to have broker-1
serve as the master and broker-2 as slave. I followed posts online and
configured borker-1 and broker-2 . I start broker-1 which completes startup
. broker-2 when started attempts to acquire lock and waits for the lock as
broker-1 holds it .
After about two hours broker-2 implicitly crashes by implicitly closing the
connection as explained by logs below .

This way broker-2 gets disengaged acting as a slave there by not achieving
the failover i am desiring in production.
in my activemq.xml mySQL datasource setting looks like
<bean id="mysql-ds" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url"
value="jdbc:mysql://######:####/######?relaxAutoCommit=true"/>
<property name="username" value="######"/>
<property name="password" value="######"/>
<property name="maxActive" value="200"/>
<property name="poolPreparedStatements" value="true"/>
</bean>
Please help if i am missing any configuration setting .
