java 读取ibm mq消息,我无法使用java从IBM MQ读取消息(I cant read the messages from IBM MQ using java)...

I am using IBM MQ version 7.5 (trial version)

I have created a two queue managers (QM1 and QM2)

Under the QM1:

port : 1421

Queues: q1(local queue)

channel: ch1 (receiver)

Under the QM2:

port :1422

Queues:q2(transmission queue),q3(remote queue)

channel:ch1 (sender)

I can send the messages through QM2's queue q3 to QM1's queue q1. I can also receive and browse the messages through the q2.

But when I use the java to read the messages from q1 I have an error

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

When I check with the IBM site they said it can cause the due to the below reasons

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

A firewall has terminated the connection.

An IOException caused the socket to be closed.

An explicit action caused the socket to be closed by one end.

The queue manager is offline.

The maximum number of channels allowed by the queue manager are already open.

A configuration problem in the Queue Connection Factory (QCF).

But all of the above are looks good in my system. what I missing , Kindly let me know.

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();

}

Adding:

version of the jar :

C:\Program Files (x86)\IBM\WebSphere MQ\java\lib>java -cp ./com.ibm.mq.jar com.ibm.mq.MQJavaLevel

Name: WebSphere MQ classes for Java

Version: 7.5.0.2

Level: p750-002-130627

Build Type: Production

After changing the channel I have received the below error

----- 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.

VRMF(7.5.0.2) QMgr(Receiver)

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.
