从MQ本地队列获取消息时，我收到以下异常。这是我的连接代码。运行代码后我遇到异常
MQJE001: An MQException occurred: Completion Code 2, Reason 2009
MQJE016: MQ queue manager closed channel immediately during connect
Closure reason = 2009

答案 0 :(得分：1)
评论员是正确的，基于看起来像MCA频道而不是MQI频道的命名。但是，当我测试到RCVR频道的客户端连接时，我会回来2539=MQRC_CHANNEL_CONFIG_ERROR。
另一方面，当使用连接到MQI通道的客户端时，2009年有很多原因。几乎所有这些都出现在QMgr的错误日志中，所以问题是“如何解决2009年？”答案是“通过重新创建错误并立即查看QMgr的AMQERR01.LOG文件。”
一些可能性包括......
许多MQ开发问题只能通过查看队列管理器生成的诊断消息来解决。除其他原因外，限制可能泄露给攻击者的信息是安全设计的一部分。 MQ管理员可以知道详细信息，但攻击者应该得到一个相当模糊的结果。在合法的应用程序开发环境中，开发人员可以访问攻击者不会访问的QMgr诊断。所以去获取错误日志。
如果由于某种原因您无法说服MQ管理员提供日志数据或者无法访问日志数据，您可以在桌面上设置自己的全功能，完全许可的免费MQ服务器。有关如何下载MQ Advanced for Developers的信息，请参见ibm-mq标记wiki。 （将鼠标悬停在代码上，然后点击弹出式对话框中的“信息”即可转到此处。）
您还可以观看No-Cost, Fully Licensed IBM MQ Sandbox这是一个视频教程，解释如何使用MQ Advanced for Developers创建专用的Red Hat虚拟机，使用所有免费和完全许可的软件，包括在何处获取虚拟化软件和Red Hat OS。
完成设置后，创建一个QMgr，配置为像Integration Test QMgr重新创建错误并检查日志。如果你连接OK并且至少无法重新创建错误，你可以回到MQ管理员，因为知道你的代码不是问题。
