连接到IBM MQ

Question

当我执行下面的代码时，出现以下错误。你能告诉我为什么吗？这听起来问题在于频道，但我验证了，但我没有找出问题的原因。我在网上尝试了很多例子，但这个问题仍然存在。

   import java.io.IOException;
import java.util.Hashtable;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.ibm.mq.MQAsyncStatus;
import com.ibm.mq.MQException;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQPutMessageOptions;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQQueueManager;
import com.ibm.mq.constants.MQConstants;

public class MQClientTest2 {

    private static final Logger LOGGER = LoggerFactory.getLogger(MQClientTest.class);

    public static void main(String args[]) {
        // Create a connection to the queue manager
        Hashtable<String, Object> props = new Hashtable<String, Object>();
        props.put(MQConstants.CHANNEL_PROPERTY, "WM.SVRCONN.001");
        props.put(MQConstants.PORT_PROPERTY, 1414);
        props.put(MQConstants.HOST_NAME_PROPERTY, "localhost");

        String qManager = "QM1";
        String queueName = "LQ1";
        MQQueueManager qMgr = null;
        try {
            qMgr = new MQQueueManager(qManager, props);

            // MQOO_OUTPUT = Open the queue to put messages. The queue is opened for use with subsequent MQPUT calls.
            // MQOO_INPUT_AS_Q_DEF = Open the queue to get messages using the queue-defined default.
            // The queue is opened for use with subsequent MQGET calls. The type of access is either
            // shared or exclusive, depending on the value of the DefInputOpenOption queue attribute.
            int openOptions = MQConstants.MQOO_OUTPUT | MQConstants.MQOO_INPUT_AS_Q_DEF;

            // creating destination
            MQQueue queue = qMgr.accessQueue(queueName, openOptions);

            // specify the message options...
            MQPutMessageOptions pmo = new MQPutMessageOptions(); // default
            // MQPMO_ASYNC_RESPONSE = The MQPMO_ASYNC_RESPONSE option requests that an MQPUT or MQPUT1 operation
            // is completed without the application waiting for the queue manager to complete the call.
            // Using this option can improve messaging performance, particularly for applications using client bindings.
            pmo.options = MQConstants.MQPMO_ASYNC_RESPONSE;

            // create message
            MQMessage message = new MQMessage();
            // MQFMT_STRING = The application message data can be either an SBCS string (single-byte character set),
            // or a DBCS string (double-byte character set). Messages of this format can be converted
            // if the MQGMO_CONVERT option is specified on the MQGET call.
            message.format = MQConstants.MQFMT_STRING;
            message.writeString("<message>Hallo Vinh</message>");
            queue.put(message, pmo);
            queue.close();

            MQAsyncStatus asyncStatus = qMgr.getAsyncStatus();
            System.out.println("valor do asyncStatus: " + asyncStatus.putSuccessCount);

        } catch (MQException e) {
            LOGGER.error("Die Verbindung zum Message Broker mit den "
                    + "Eigenschaften {} und dem QueueManager {} konnte nicht hergestellt werden.", props, qManager, e);
        } catch (IOException e) {
            LOGGER.error("Fehler beim Schreiben der Message.", e);
        } finally {
            try {
                qMgr.disconnect();
            } catch (MQException e) {
                LOGGER.error("Die Verbindung konnte nicht geschlossen werden.", e);
            }
        }
    }
}

这是执行程序时发生的错误：

下面我从我配置频道的地方放置了图像。

删除所有队列管理器并重新创建新队列管理器后，我收到了这个新错误：

我安装IBM MQ的目录：

执行命令set | findstr MQ后：

Answer 1

  

MQJE001：CódigodeConclusão'2'，Razão'2540'。

您是否查找了原因代码2540？所有MQ原因代码都记录在MQ Knowledge中。这是2540 (MQRC_UNKNOWN_CHANNEL_NAME)

的RC

以下是包含所有MQ Reason Codes。

的页面

在您的示例中，您使用了端口＃1414，但您的PC上有3个队列管理器。您可能连接到错误的端口，因此队列管理器错误。如果您不记得为队列管理器设置的端口号，那么您只需单击“监听器”，然后查看“LISTENER.TCP”对象用于该特定队列管理器的端口号。每个队列管理器都需要一个UNIQUE端口＃。

所以基本上，当你没有注意到你正在做的事情时，你会通过删除你的队列管理员来解雇自己。

  

MQJE001：CódigodeConclusão'2'，Razão'2035'。

您是否查找了原因代码2035？这是2035 (MQRC_NOT_AUTHORIZED)

的RC

您是否使用正确的端口＃作为新队列管理器？您是否在新队列管理器中创建了频道？您是否正在使用SYSTEM。*频道或在'mqm'组中使用UserId运行，因为CHLAUTH止回规则可能会阻止您。阅读Morag关于CHLAUTH止回规则的帖子：
