Question

我的下面是代码适用于MQ6，但对于MQ7，它给出异常

'package javaapplication1;

import java.io.*;
import java.net.*;
import java.util.*;
import java.util.TimerTask;
 import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQException;
    import com.ibm.mq.MQQueue;
    import com.ibm.mq.MQQueueManager;
    import com.ibm.mq.constants.CMQC;
class Connectivity 
{
    public static void main(String args[]) throws MQException
    {
       String qManager="";
       int port_num=0;
    int openOptions =  CMQC.MQOO_FAIL_IF_QUIESCING + CMQC.MQOO_INPUT_SHARED;

    MQEnvironment.hostname = "Host_name";
    MQEnvironment.port = port_num;
    MQEnvironment.channel = "Chn_name";
    System.out.println("Connecting to queue manager: " + qManager);
            Hashtable props = new Hashtable();

            // Change the host name to your host name. Leave it as it is if 
            // queue manager is on the same machine
            props.put(CMQC.HOST_NAME_PROPERTY, "Host_name"); 
            props.put(CMQC.PORT_PROPERTY, port_num);
            props.put(CMQC.CHANNEL_PROPERTY, "Chn_Name");

            MQQueueManager qMgr = new MQQueueManager(qManager, props);
    //MQQueueManager qMgr = new MQQueueManager("SW1_QM");

    MQQueue destQueue = qMgr.accessQueue("Q_Name",   openOptions);

    System.out.println("E_RETRY size:" + destQueue.getCurrentDepth());
    destQueue.close();
    qMgr.disconnect();
    }


}'

我在线上得到例外

＆＃39; System.out.println（＆＃34; E_RETRY size：＆＃34; + destQueue.getCurrentDepth（））;＆＃39;

，异常消息是

'MQJE001: Completion Code 1, Reason 2068
Exception in thread "main" com.ibm.mq.MQException: MQJE001: Completion Code 1, Reason 2068
    at com.ibm.mq.MQManagedObject.inquire(MQManagedObject.java:257)

    at com.ibm.mq.MQQueue.getCurrentDepth(MQQueue.java:1478)
    at javaapplication1.Connectivity.main(Connectivity.java:36)
Java Result: 1'

请帮帮我......

您的打开选项不包含MQOO_INQUIRE，这是获取队列深度所必需的。我期望MQRC 2038，因为没有指定MQOO_INQUIRE选项。

还不确定为什么要初始化MQEnvironment，并且要将属性哈希表传递给MQQueueManager构造函数。

无论如何，这里是获取本地队列队列深度的示例代码。

public static void getQueueDepth()
{
            String qManager="QM1";
    int port_num=1414;
    int openOptions =  CMQC.MQOO_FAIL_IF_QUIESCING + CMQC.MQOO_INPUT_SHARED + CMQC.MQOO_INQUIRE;

    try {
            Hashtable props = new Hashtable();

            props.put(CMQC.HOST_NAME_PROPERTY, "localhost"); 
            props.put(CMQC.PORT_PROPERTY, port_num);
            props.put(CMQC.CHANNEL_PROPERTY, "SYSTEM.DEF.SVRCONN");

            MQQueueManager qMgr = new MQQueueManager(qManager, props);

            MQQueue destQueue = qMgr.accessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE",   openOptions);

            System.out.println("E_RETRY size:" + destQueue.getCurrentDepth());
            destQueue.close();
            qMgr.disconnect();
    }catch(MQException mqe){
        System.out.println(mqe);
    }
}

v6和v7队列管理器之间的队列属性是否可能不同？ documentation for the error message表示解析到队列的远程实例的群集队列可能会发生这种情况。

您是否确认destQueue实际上是一个有效的队列？

需要访问MQ 7的队列深度
