Hi,
We have MQ set up as below.
Server1
QM1
QLOCAL_A
Server2
QM2
QLOCAL_A
Server3
QM3
QLOCAL_B
Queue managers are not clustered ( using remote queue definitions)
Request messages come from QM1 or QM2 to QLOCAL_B of QM3.
Application will be triggered when the message comes to QLOCAL_B which has to process the message and send the response back to QLOCAL_A of QM1 or QM2 depending on where the request message came from. Request message have ReplyToQueue and ReplyToQueueManager name on MQMD.
In some cases our application will not send the response message back
immediately. So we need to store ReplyToQueue and ReplyToQueueManager name in SQl server database. Now the question is which is the best way to send the response message to the appropriate queue manager.
Do I have to use 2 remote queue definitons on QM3 with the name QM1
and QM2 and in the application instead of giving
.........................................................
Set QueueRes = QMgr.AccessQueue(ResQueueName, _
MQOO_OUTPUT + MQOO_FAIL_IF_QUIESCING)
where ResQueueName is the name of the remote queue defintion
..........................................................
do I have to set MQQueue.RemoteQueueManagerName
MQQueue.RemoteQueueName and then issue put call??
os win 2000
Queue managers are not clustered ( using remote queue definitions)
MQ5.3
VB program is used to process the message
Can anyone let me know the best way to do this.
Thanks

Why don't you send your reply back through transmisson queues instead of remote queues
define transmissons queues QM1 and QM2 on QM3
Based on the ReplyToQueueManager you can send the mesaage to either
QM1 or QM2
This scenario should definitely work |

Prahasith,
If I create 2 transmisson queues QM1 and QM2 on QM3, in my application do I have to pull the replyToQueueManagerName and then access the transmisson queue as below?
Set QueueResponse = QMgr.AccessQueue(replyToQueueManagerName,
_ MQOO_OUTPUT + MQOO_FAIL_IF_QUIESCING)
Thanks

I don't "do" VB, so I could be wrong on this, but in other languages you just use both the reply-to Queue Manager and Queue when openeing the Queue and it 'uses' the transmission queue. You don't refer to it explicitly.
Cheers,
