我使用的是IBM版本7.5 (试用版)

我创建了两个队列管理器(QM1和QM2)

在QM1:下

港口: 1421

队列:q1(本地队列)

频道: ch1 (接收机)

在QM2:下

港口:1422

队列:Q2(传输队列)，q3(远程队列)

频道:CH1(发件人)

我可以通过QM2的队列q3向QM1的队列q1发送消息。我还可以通过q2接收和浏览消息。

但是，当我使用java从q1读取消息时，会出现一个错误。

MQJE001: An MQException occurred: Completion Code 2, Reason 2009   
MQJE016: MQ queue manager closed channel immediately during connect    
Closure reason = 2009    
MQJE001: Completion Code 2, Reason 2009

当我查看IBM站点时，他们说这可能会导致以下原因

http://www-01.ibm.com/support/docview.wss?uid=swg21226703

防火墙已经终止了连接。
IOException导致套接字关闭。
显式操作导致套接字由一端关闭。
队列管理器脱机。
队列管理器允许的最大通道数已经打开。
队列连接工厂(QCF)中的配置问题。

但在我的系统中，以上所有的一切看起来都很不错。我错过了什么，请告诉我。

public static void main(String[] args) throws MQException {

MQEnvironment.hostname="localhost";
MQEnvironment.channel="ch1";
MQEnvironment.port=1421;
MQQueueManager qMgr= new MQQueueManager("QM1");
MQQueue outputQueue =qMgr.accessQueue("q1", MQC.MQOO_INQUIRE | MQC.MQOO_BROWSE | MQC.MQOO_INPUT_AS_Q_DEF);


//Checking for messages in queue
int i=outputQueue.getCurrentDepth();
System.out.println("Number of messages in  queue: "+i);


outputQueue.close();
qMgr.close();
qMgr.disconnect();
}

增加：

jar的版本：

C:\Program (X86)\IBM\ MQ\java\lib>java MQ\java\lib>java -cp ./com.ibm.mq.jar com.ibm.mq.MQJavaLevel

名称: WebSphere MQ类

版本: 7.5.0.2

等级:P 750-002-130627

建造类型:生产

更改通道后，我收到以下错误

    ----- amqrmrsa.c : 898 --------------------------------------------------------
10/20/2017 02:17:37 - Process(16340.40) User(MUSR_MQADMIN) Program(amqrmppa.exe)
                     Host(user1) Installation(Installation1)
                     VRMF(7.5.0.2) QMgr(Receiver)

AMQ9777: Channel was blocked

EXPLANATION:
The inbound channel 'SYSTEM.DEF.SVRCONN' was blocked from address '127.0.0.1'
because the active values of the channel matched a record configured with
USERSRC(NOACCESS). The active values of the channel were 'CLNTUSER(fresher)'.
ACTION:
Contact the systems administrator, who should examine the channel
authentication records to ensure that the correct settings have been
configured. The ALTER QMGR CHLAUTH switch is used to control whether channel
authentication records are used. The command DISPLAY CHLAUTH can be used to
query the channel authentication records.

AMQ9999: Channel 'SYSTEM.DEF.SVRCONN' to host 'user1 (127.0.0.1)' ended
abnormally.

EXPLANATION:
The channel program running under process ID 16340(5348) for channel
'SYSTEM.DEF.SVRCONN' ended abnormally. The host name is 'user1
(127.0.0.1)'; in some cases the host name cannot be determined and so is shown
as '????'.
ACTION:
Look at previous error messages for the channel program in the error logs to
determine the cause of the failure. Note that this message can be excluded
completely or suppressed by tuning the "ExcludeMessage" or "SuppressMessage"
attributes under the "QMErrorLog" stanza in qm.ini. Further information can be
found in the System Administration Guide.
