Question

我有一个ActiveMQ实例将传入的消息桥接到WebsphereMQ。如何控制ActiveMQ连接到WebsphereMQ所使用的连接数？

根据http://www-01.ibm.com/support/docview.wss?uid=swg21665128，似乎我必须编写自己的连接池，但那么默认行为是什么？

My Spring配置桥：

<bean id="wmqConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
    <property name="queueManager" value="queueManager"/>
    <property name="connectionNameList" value="connectionNameList"/>
    <property name="channel" value="channel"/>
    <property name="transportType">
        <util:constant static-field="com.ibm.msg.client.wmq.WMQConstants.WMQ_CM_CLIENT"/>
    </property>
    <property name="clientID" value="clientID"/>
</bean>

<bean id="cachedWmqConnectionFactory"
      class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="targetConnectionFactory">
        <ref local="wmqConnectionFactory" />
    </property>
    <property name="reconnectOnException" value="true" />
    <property name="sessionCacheSize" value="1" />
</bean>

<bean id="wmqPatchedJmsConnector" class="org.apache.activemq.network.jms.JmsQueueConnector">
    <property name="name" value="ActiveMq-WMQ-Bridge"/>
    <property name="outboundQueueConnectionFactory" ref="cachedWmqConnectionFactory"/>
    <property name="outboundQueueBridges">
        <list>
            <bean class="org.apache.activemq.network.jms.OutboundQueueBridge"><constructor-arg value="q1"/></bean>
        </list>
    </property>
    <property name="inboundQueueBridges"><list/></property>
</bean>

<amq:broker useJmx="true" brokerName="${activemq.brokername:my-amq}" dataDirectory="${activemq.datadirectory}" persistent="true">
    <amq:destinationPolicy>
        <amq:policyMap>
            <amq:policyEntries>
                <amq:policyEntry queue="&gt;" queuePrefetch="1">
                    <amq:deadLetterStrategy>
                        <amq:individualDeadLetterStrategy queuePrefix="DLQ." useQueueForQueueMessages="true" />
                    </amq:deadLetterStrategy>
                </amq:policyEntry>
            </amq:policyEntries>
        </amq:policyMap>
    </amq:destinationPolicy>

    <amq:jmsBridgeConnectors>
        <ref bean="jmsConnector"/>
    </amq:jmsBridgeConnectors>

    <amq:managementContext>
        <amq:managementContext createConnector="false" />
    </amq:managementContext>

    <amq:transportConnectors>
        <amq:transportConnector name="humble-transport"
            uri="${local.host}" discoveryUri="${multicastGroup}"
            updateClusterClients="true" rebalanceClusterClients="true"
            updateClusterClientsOnRemove="true" />
    </amq:transportConnectors>
</amq:broker>

谢谢！

默认行为是每次进行JmsConnection时都会创建一个新的MQ Connection。正如您所说，您可以实现自己的层来重用连接，而不是定期关闭它们并创建新连接。

如果通过＆＃34;控制＆＃34;你的意思是，＆＃34;停止过多的＆＃34;您应该查看SVRCONN上的MAXINST和MAXINSTC参数。

如何在ActiveMQ出站桥中设置maxConnections？
