Error handling 无法模拟MQ原因代码2009

我试图模拟WebSphere MQ原因代码2009，以便在下面的JMS代码中处理，但无法获得它。相反，我得到了2059英镑。我所做的就是在进行连接调用时断开SVRCONN通道。如何在示例代码中获得2009。 我在再次建立连接和使用事务会话之前添加了睡眠时间。为了正确处理原因代码2009，队列管理器最终不会因为频繁的不成功连接尝试而崩溃，还可以做些什么。 请找到密码

2009

是

MQRC\u连接断开的。您是否考虑过拔掉网络电缆或关闭连接通过的网络接口？在笔记本电脑上运行代码时，这很容易。对于服务器，您可以尝试通过SSH代理或其他可以关闭的虚拟接口路由连接

要回答问题的第二部分，请确保程序在重新连接尝试之间休眠几秒钟。或者，最好使用现代版本的WMQ客户端并使用自动重新连接选项。这将进行几次快速重试，然后在后续重试时稍微降低速度。
您可以将通道的空闲连接超时设置为某个较小的值。创建连接，等待连接超时，然后尝试使用它。你将得到2009年。
