How does the requesting app on QMD understand which reply (response) goes with the request?

Hmm, interesting, I had read the OP as suggesting that QMD was the responding app, not the requesting app.

Hisham, can you confirm which way round is the setup.

Is it:-

QMD is requesting app, then either QMA or QMB is responding app
QMA or QMB is requesting app, QMD is responding app

Cheers,
Morag

QMA or QMB is requesting app, QMD is responding app

Thanks, now please take a look at my earlier question too?

T24 Application has configuration file that must be filled with below, so what suppose to type in MQQUEUE OUT field the QR name ESBMQ01STGDC1 or the LQ_T24_OUT

BACKOUTQUEUE: N/A

Are you telling us that the T24 application does not use the MQMD.ReplyToQ and MQMD.ReplyToQMgr fields when sending its reply back and instead always puts the response message to the queue in the configuration file attribute MQQUEUE OUT?

Cheers,
Morag

Yes T24 application uses these configuration before send the response

Where is queue LQ_T24S_IN? This is your first reference to this queue name.

Exactly and precisely, how does T24 app uses these configuration before the send? Does "send" = MQPUT? Or, is there a send-exit that manipulates the XQH before the SENDER channel transmits (sends) the message?

Exactly and precisely, how does the T24 app use this configuration to determine whether A or B is the destination for the response?

The below scenario still under testing as it is new setup:

There is TCServer in between the MQ "QMgr D ""T24STGDC1"" which is installed on the same T24 server and tne T24 application, once the msg arrived in QMgr D the TCServer pull the msg and process on it then puts the response again in QMgr D then send it to back to the requester Qmgr A "ESBIIB01STGDC1" or B "ESBIIB02STGDC1" via QMgr C

The request sent successfully to T24 application throw out QR defined on QMgr A & B to send the request to gateway QMgr C "GWYMQ01STGDC1" and there is QMgr alias defined on it to deliver the request to IN Q on QGgr D then TCServer pull the msg to process on it, Hereunder the defined QRs for the request.

QMgr A:
DEFINE QREMOTE(RQ_GW_T24_OUT) RNAME(LQ_T24S_IN) RQMNAME('RQ_T24_IN') XMITQ(' ') CLUSTER('GTWYCLUSTER') REPLACE ;
QMgr B:
DEFINE QREMOTE(RQ_GW_T24_OUT) RNAME(LQ_T24S_IN) RQMNAME('RQ_T24_IN') XMITQ(' ') CLUSTER('GTWYCLUSTER') REPLACE ;
QMgr C:
DEFINE QREMOTE('RQ_T24_IN') RNAME(' ') RQMNAME('T24STGDC1') XMITQ('TQ_T24_IN') CLUSTER(' ') REPLACE ;
QMgr D:
DEFINE QLOCAL(LQ_T24T_IN) MAXDEPTH(50000) DEFBIND(NOTFIXED);

@hughson @bruce2359, I found another solution but I'm not sure is it will make workload balance or will send the response to the requester?, I tested it by the MQ explorer and MSGs sent successfully to QMgr A & B, I could not test it in real msg as the developer in vacation to change the code accordingly.
So please can tell me, Is it will make workload balance or will send the response msg to the requester?

QMgr D "T24STGDC1":
DEFINE QREMOTE('RQ_T24_To_ESB') RNAME(LQ_T24_OUT) RQMNAME('RQ_T24_01S_OUT') XMITQ('TQ_T24_IN') CLUSTER(' ') REPLACE ;

QMgr C "GWYMQ01STGDC1":
DEFINE QREMOTE('RQ_T24_01S_OUT') RNAME(' ') RQMNAME(' ') XMITQ('TQ_T24_IN') CLUSTER('GTWYCLUSTER ') REPLACE ;

In order to answer that, you'll have to tell us how you tested it in Explorer, specifically, what did you fill in on the MQPUT in Explorer. How did you tell MQ Explorer you wanted to go to QMA or QMB for example.

And how did you tell it you wanted it to go to QMA or QMB? If you didn't, then the answer to your question is that it is round-robining, and I don't believe that is what you need.

You need your application to put to MQMD.ReplyToQ and MQMD.ReplyToQmgr.

So as per your advise I have to define below on QMgr D "T24STGDC1" only and the response will be forwarded to the XMITQ on gateway QMgr C "" to send the response back the requester QMgr A or B based on the MQMD.ReplyToQ and MQMD.ReplyToQmgr. AM I understand right?

For clarity, How the QMgr D will forward the response to gateway QMgr according to below definition?

DEFINE QREMOTE(ESBMQ01STGCD1) RNAME(' ') RQMNAME(ESBMQ01STGCD1) XMITQ(TQ_IN)

DEFINE QREMOTE(ESBMQ02STGCD1) RNAME(' ') RQMNAME(ESBMQ02STGCD1) XMITQ(TQ_IN)

DEFINE QREMOTE(ESBMQ02STGCD1) RNAME(' ') RQMNAME(ESBMQ02STGCD1) XMITQ(TQ_IN)

QMgr D will see that the MQPUT is targeted to ESBMQ01STGCD1 for example, because that will be in the MQOD.ObjectQMgrName field. This will mean it knows to put the message on XmitQ TO_IN as per the definition above. Once it gets to QMC, QMC will know what to do with it because it is aware of queue manager ESBMQ01STGCD1 by name (due to being in a cluster with it).

Make sure when testing this that you fill in both queue name and queue manager name on your test MQPUT. I can't remember whether MQ Explorer can do that, but I showed you the amqsput way of doing it before.

Morag

I've asked you if this is a new app? I don't understand what you mean by "scenario" and "new setup".

Please be precise in your answers. Is this is an entirely NEW application - both requesting and responding are new apps? The qmgrs are new? This entire system has never been in production before? No other versions of this are currently in production or pre-prod?

I/we are trying to determine what exactly "new setup" means to you. I'm trying to determine if you are creating something new OR fixing something that previously worked, but now is broken.

I previously asked you if you have attended IBM MQ training - in a classroom or online? What experience, if any, you have with IBM MQ product? MQ things like sample programs for testing, name-resolution, queue types, message routing, DLH, XQH, and such, are discussed in basic training, and with hands-on lab exercises to demonstrate. I encourage you to get training so that you can help yourself resolve these and other problems.

Are you are an application developer, MQ administrator, or something else?

I think you need:-

i.e. you want to connect to T24STGDC1 and put to the equivalent of ReplyToQ on ReplyToQMgr
