Setting up network of brokers without shared database or file
system
I am using ActiveMQ 5.2 with following configuration:
<broker brokerName="US_Integ_RSP" persistent="true" useJmx="true"
xmlns="http://activemq.apache.org/schema/core">
<!-- Destination specific policies using destination names or
wildcards -->
<destinationPolicy>
<policyMap>
<policyEntries>
<policyEntry queue=">" memoryLimit="512mb">
<deadLetterStrategy>
<individualDeadLetterStrategy queuePrefix="DLQ." />
</deadLetterStrategy>
</policyEntry>
<policyEntry topic=">" memoryLimit="128mb">
<dispatchPolicy>
<strictOrderDispatchPolicy/>
</dispatchPolicy>
<subscriptionRecoveryPolicy>
<lastImageSubscriptionRecoveryPolicy/>
</subscriptionRecoveryPolicy>
</policyEntry>
</policyEntries>
</policyMap>
</destinationPolicy>
<!-- Use the following to configure how ActiveMQ is exposed in JMX
-->
<managementContext>
<managementContext createConnector="true"/>
</managementContext>
<persistenceAdapter>
<journaledJDBC journalLogFiles="5" dataDirectory="./var/" />
</persistenceAdapter>
<transportConnectors>
<transportConnector name="openwire" uri="tcp://localhost:61616"
discoveryUri="multicast://default"/>
</transportConnectors>
<networkConnectors>
<networkConnector name="default-us-integ-rsp"
uri="multicast://default" dynamicOnly="true" conduitSubscriptions="false"
decreaseNetworkConsumerPriority="false" />
</networkConnectors>
I am using two activemq servers and connecting to them from Spring using URL
prod.USAmazon.JmsBrokerUrl="failover://(tcp://rspp-prod-na-0104.sea3.amazon.com:61616,tcp://rspp-prod-na-1007.vdc.amazon.com:61616?trace=false)?initialReconnectDelay=100";
and then registering listener as
<bean
class="org.springframework.jms.listener.DefaultMessageListenerContainer"
init-method="start" destroy-method="stop">
<property name="connectionFactory"
ref="staticJmsConnectionFactory"/>
<property name="destination" ref="responseQueue"/>
<property name="messageListener" ref="asyncResponseAdapter"/>
<property name="concurrentConsumers" value="1"/>
<property name="sessionTransacted" value="true"/>
</bean>
However, I am getting connected to only one of the server. If I increase
concurrentConsumers to higher value, I see that I am connected to both, but
is there a way to connect to both servers with only 1 consumer. Now, the
publisher might connect to one of the server and add the message to the
queue, but listener is on the other side. My question is that how do I setup
network of brokers to pass message to the right consumer.
