The code below works well for putting messages into MQ. The load balancing works perfect. I tried to obtain the report but no report is generated. How do I solve the problem?. Did I miss something?.

Java code

qMgr = new MQQueueManager(qManager);
int openOptions = MQC.MQOO_OUTPUT ;
MQQueue MQ1_RQSTIN = qMgr.accessQueue("QM1.RQSTIN",openOptions);
MQMessage hello_world = new MQMessage();
hello_world.putApplicationName = "src_mqsample.txt";
hello_world.report = MQC.MQRO_COA ;
hello_world.replyToQueueName = "QM1.REPLY";

File file = new File("C:
Documents and Settings
My Documents
JCreator LE
MyProjects
MQSample
src_mqsample.txt");
StringBuffer contents = new StringBuffer();
BufferedReader reader = null;
reader = new BufferedReader(new FileReader(file));
String text = null;


while((text = reader.readLine())!= null)
{
contents.append(text).append(System.getProperty("line.separator"));
}

hello_world.writeObject(contents);
MQPutMessageOptions pmo = new MQPutMessageOptions();
MQ1_RQSTIN.put(hello_world,pmo);

You should also define replyToQueueManager beside replyToQueueName

But no report is return to the queue manager QM1 queue QM1.REPLY

You have not received COA because your message has NOT been delivered.

The target Q refer a Q on QM2
 DEFINE QREMOTE(QM1.RQSTIN) RNAME(QM1.RQSTIN) RQMNAME(QM2)
which refer an unexisting Q
 DEFINE QREMOTE(QM1.RQSTIN) RNAME(QM1.RQSTIN) RQMNAME(ANY.QMGR)

Try a simple structure first.
Make a drawing on it, signing the references and message paths.

Actually the mq script is a load balancing script. At QM3 it decides to route the message to QM4 or QM5.

In QM4 and QM5 I have:
DEFINE QREMOTE(QM1.REPLY) RNAME(QM1.REPLY) RQMNAME(QM3) XMITQ('') CLUSTER(CLUS2)
so why cant the QM4 and QM5 use this remote queue to send a COA to QM1?

I repeat: You have not received COA because your message has NOT been delivered.
DEFINE QREMOTE(QM1.RQSTIN) RNAME(QM1.RQSTIN) RQMNAME(ANY.QMGR) XMITQ(Q3.XMIT)

The original message is not deliverable, you have no queue manager "ANY.QMGR".
All messages are  transmitted to QM3, where you can find them in the dead letter queue
(which is probably your DEAD.QUEUE, if defined so, or in a default transmission queue
if it is declared.)

How do I resolve this problem without affecting the load balancing capability of the MQ script?.

I check the DEAD.QUEUE and Transmission Queue but the current depth is 0.

I also did the following:

Java code:

hello_world.report = MQC.MQRO_COD ;
hello_world.replyToQueueName = "ANY.QMGR";
hello_world.replyToQueueManagerName = "QM3";

For QM4 and QM5 I:

DEFINE QALIAS(ANY.QMGR) TARGQ(QM1.REPLY) CLUSTER(CLUS2)

But no report is sent to QM1.

I even check SYSTEM.DEAD.LETTER.QUEUE and found that the currentdepth is 0.

ANY.QMGR does not exist, can I declare one with no queue and channel definition declared.
