java - IBM MQ Server 8.0.0.4 客户端库

Question

我在使用 IBM MQ 8.0.0.4 时遇到了一个奇怪的问题。我的命令行应用程序(Java 8)从Windows环境连接到Linux服务器中安装的MQ服务器。应用程序在消息到达时从特定队列中读取消息。我使用以下 jar 作为客户端库 (8.0.0.4-WS-MQ-Install-Java-All.jar):-

com.ibm.mq.allclient.jar
com.ibm.mq.traceControl.jar
fscontext.jar
jms.jar
JSON4J.jar
providerutil.jar

应用程序照常运行，没有任何问题。可以通过“control+c”来停止。完成后，调用 ThreadGroup.interrupt() 并且应用程序按预期停止。不期望的是:-

1) 以下堆栈跟踪

2) 创建名为 FFDC 的文件夹，其中包含名为 JMSCC0001.FDC、JMSCC0002.FDC 等的文件。

我之所以说堆栈跟踪是意外的，是因为它说“java.library.path 中没有 mqjbnd”，这意味着应用程序正在以绑定(bind)模式连接 MQ 服务器。但我正在客户端模式下连接，如您所见:

当我使用属于 Websphere MQ 7.0 的客户端库时，没有遇到上述堆栈跟踪。请帮忙。

Answer 1

事实上，您有 MQRC_UNEXPECTED_ERROR 和 FDC 文件，这意味着您确实应该为此向 IBM 打开一个 PMR。这是不应该发生的。
