IBM MQ 调用失败，compcode“2”（'MQCC_FAILED'）原因“2059”

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 with\without 用户名和密码。当我使用安装在我的机器 (localhost) 上的 IBM MQ 尝试相同的代码时，它运行顺利。

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();

    }

这给出了以下异常：

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.

这个异常是什么意思？我该如何解决？

Answer 1

异常中的关键错误是：

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 中的一个已知问题：

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。我建议您使用当前的 LTS（长期支持）版本 9.0.0.3。

如果您查看 APAR 并将其与您的问题进行比较，不同之处在于您正在连接到使用 CCSID 720 (MSDOS ARABIC) 设置的远程队列管理器。问题是您正在使用的 Java JRE 不支持此 CCSID，并且由于缺陷，客户端不会尝试将 CCSID 重新协商为 JRE 支持的 CCSID，并且连接失败并出现 2195 错误。

Answer 2

来自 JoshMC 的回答，阅读后：
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 版本构建应用程序。（我确实做到了。）
