JMSWMQ2020：无法连接到队列管理器

Question

我正在尝试使用 ccdt.tab 文件连接到队列管理器。这是我尝试过的：

String CHANNEL_TABLE_PATH = "/usr/dev/ccdt.tab";
URL chanTableUrl = new URL("file://"+ CHANNEL_TABLE_PATH);
connectionFactory.setCCDTURL(chanTableUrl);
connectionFactory.setQueueManager("*");
MQQueueConnection connection = (MQQueueConnection) connectionFactory.createQueueConnection();
connection.start();

这是我的 ccdt.tab

里面的内容

DIS CHL(*) QMNAME CONNAME
Display Channel details.
   CHANNEL(C.TEST.1)                     CHLTYPE(CLNTCONN)
   CONNAME(host1.test.com(1511), host2.test.com(1512))   QMNAME(QQ)
Display Channel details.
   CHANNEL(C.TEST.2)            CHLTYPE(CLNTCONN)
   CONNAME( )                              QMNAME( )

但是，我确实在队列连接上遇到了错误：线程 "main" java.lang.Exception 中的异常：JMSWMQ2020：无法使用连接模式 'Client' 和提供的 CCDT URL 'file:/use/test/ccdt.tab' 连接到队列管理器“*”，请参阅链接异常获取更多信息。

我尝试更改为：setQueueManager("*QUEMANAGER") 或 setQueueManager("*") 或 setQueueManager("QMGRNAME") 它返回相同的错误。我还检查了 ssl 连接，它运行良好。

此外，我尝试使用此代码连接到 MQ 服务器，它工作得很好：

connectionFactory.setConnectionNameList("host1.test.com(1511), host2.test.com(1512)");
connectionFactory.setClientReconnectOptions(67108864);
connectionFactory.setClientReconnectTimeout(1800);
connectionFactory.setQueueManager("QQ");
connectionFactory.setChannel("C.TEST.1");
MQQueueConnection connection = (MQQueueConnection) connectionFactory_.createQueueConnection();
connection.start();

有谁知道出了什么问题以及如何解决？

Answer 1

当您指定 setQueueManager("*") 时，错误是：

AMQ9204: Connection to host '' rejected.

这是因为 IBM MQ 可以解析 CCDT 中两个通道中的任何一个。通道 C.TEST.2 没有 CONNAME 因此当 MQ 选择通道时会导致上述错误。如果您尝试多次连接，如果它选择频道 C.TEST.1.

，您可能会成功几次

当您指定 setQueueManager("QQ") 时，错误是：

JMSCMQ0001: WebSphere MQ call failed with compcode '2' ('MQCC_FAILED') reason '2058' ('MQRC_Q_MGR_NAME_ERROR').

这是因为远程队列管理器名称不是 QQ。

您有两种选择来解决此问题：

使用setQueueManager("*QQ")，这将导致 MQ 使用 QQ 通道，但使用前导 * 它将允许您连接到任何队列管理器侦听 CONNAME
如果需要，您也可以使用 setQueueManager("*")，但您需要使用 MQ v8 或更高版本 runmqsc 来编辑 CCDT 并删除第二个通道 DELETE CHL(C.TEST.2).通过这样做，* 只能解析到剩下的单个通道 QQ，并且还允许您连接到侦听 [=14= 中指定的主机和端口的任何队列管理器]
