Question

我正在尝试向IBM MQ（版本：9.0.0.0）发送消息，代码如下 *我试过没有用户名和密码的\。当我在我的机器（localhost）上安装IBM MQ时尝试相同的代码时，它可以顺利运行。

private static void foo() throws JMSException {
        Request request = new Request();
        request.setRequestKey("11-12347");
        request.setQueryString("This is a query string!");

        MQQueueConnectionFactory cf = new MQQueueConnectionFactory();
        cf.setHostName("192.168.1.107");
        cf.setPort(1414);
        cf.setAppName("WMQ Tester");
//        cf.createConnection(sccsid, sccsid)
        cf.setIntProperty(WMQConstants.WMQ_CONNECTION_MODE, WMQConstants.WMQ_CM_CLIENT);
        cf.setQueueManager("SanctionManager");
        cf.setChannel("system.def.sanction");

        MQQueueConnection connection = (MQQueueConnection) cf.createQueueConnection("hanash", "hanash1");
        MQQueueSession session = (MQQueueSession) connection.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);

        MQQueue queue = (MQQueue) session.createQueue("queue:///SanctionQueue");
        MQQueueSender sender = (MQQueueSender) session.createSender(queue);

        ObjectMessage objectMessage = session.createObjectMessage(request);
        connection.start();
        sender.send(objectMessage);
        session.commit();

    }

这给出了以下例外：

Exception in thread "main" com.ibm.msg.client.jms.DetailedJMSException: JMSWMQ0018: Failed to connect to queue manager 'SanctionManager' with connection mode 'Client' and host name '192.168.1.107(1414)'.
Check the queue manager is started and if running in client mode, check there is a listener running. Please see the linked exception for more information.

这个例外是什么意思？我该如何解决？

Answer 1

例外中的关键错误是：

Caused by: com.ibm.mq.jmqi.JmqiException: CC=2;RC=2195;AMQ6047: Conversion not supported. [1=720,5=???]
Caused by: java.io.UnsupportedEncodingException: 720

这似乎是以下APAR中记录的IBM MQ v9.0.0.0中的已知问题：

IT17154: Java client fails to connect to z/OS with exception 'AMQ6047: conversion not supported' in a non-IBM Java runtime

此APAR已在9.0.0.1中修复。我建议你使用9.0.0.3，这是当前的LTS（长期支持）版本。

如果您查看APAR并与您的问题进行比较，则区别在于您要连接到使用CCSID 720（MSDOS ARABIC）设置的远程队列管理器。问题是您使用的Java JRE不支持此CCSID，并且由于存在缺陷，客户端不会尝试将CCSID重新协商为JRE支持的CCSID，并且连接因2195错误而失败。

Answer 2

从JoshMC回答，看完后：
IT17154: Java client fails to connect to z/OS with exception 'AMQ6047: conversion not supported' in a non-IBM Java runtime

解决该问题的一种方法是使用IBM Java版本来构建应用程序。（我实际上是这样做的。）

IBM MQ调用失败，编译'2'（'MQCC_FAILED'）原因'2059'
