Question

我正在使用Web sphere版本7.5，这是否需要System Broker来启动MQ服务。如何通过Java代码访问时启动MQ服务。目前，通过代码

访问时，我遇到以下异常

MQJE001：发生MQException：完成代码2，原因2009 MQJE016：MQ队列管理器在连接期间立即关闭通道关闭原因= 2009

com.ibm.mq.MQException：MQJE001：发生MQException：完成代码2，原因2009

MQJE016：MQ队列管理器在连接期间立即关闭通道关闭原因= 2009

我使用的代码如下所示

我收到了以下错误日志 9/24/2016 14:09:24 - 进程（1956.7）用户（MUSR_MQADMIN）程序（amqrmppa.exe）主机（ABHI-PC）安装（安装1） VRMF（7.5.0.2）QMgr（QM_ORANGE）

AMQ9208：从主机Aneesh（192.168.0.7）收到错误。

说明：通过TCP / IP从Aneesh（192.168.0.7）接收数据时发生错误。这个可能是由于通信故障。行动：来自TCP / IP recv（）调用的返回码是10054（X'2746'）。记录这些值并告诉系统管理员。

Answer 1

您的应用程序正在_queueManager.disconnect()方法中调用read。这将关闭与队列管理器的连接。然后，您的应用程序使用相同的disconnected _queueManager对象调用accessQueue方法。这将因连接错误而失败。

建议您从queueManager.disconnect()方法中删除read，然后尝试。

<强> 更新

一些建议：

1）通过添加此行MQEnvironment.properties.put(MQConstants.TRANSPORT_PROPERTY,CMQC.TRANSPORT_MQSERIES_CLIENT)

将传输类型设置为客户端

2）确保您使用的频道QM_ORANGE.QM_APPLE是服务器连接（SVRCONN）类型频道。

这个问题可能有所帮助：MQ queue manager closed channel immediately during connect
