Sending MSMQ messages to BizTalk 2004
|
|
| Mark Abrams 2004-05-30, 10:46 am |
| I have an orchestration that receives messages via the BizTalk Message Queuing (MSMQT) adapter for BizTalk 2004. The local queue is marked as being non-transactional. If a remote application sends a non-transactional MSMQ message to the BizTalk queue ever
ything is fine.
However, if the remote application sends a transactional message to the BizTalk queue, an event is logged in the application log stating that "The message was sent to a non-transactional queue within a transaction.". This is what I would expect. However,
the actual message that was sent has vanished. It is not in HAT, nor does it appear in any dead queue. The MSMQ Help states that sending a transactional message to a non-transactional queue, or a non-transactional message to a transactional queue, the me
ssage will be diverted to the Dead-Letter queue. But in MSMQT, there does not appear to be a dead-letter queue.
Has anyone come across this "feature" of MSMQT ?? I find it a bit worrying that the MSMQ message vanishes, after all, it is supposed to be a reliable transport protocol.
Thanks for any help,
Mark.

| Mark,
I'm a little confused about this. If you are using an MSMQT receive location you do not create a real MSMQ queue. You only need to create a queue when you are sending from BizTalk and it seems that only remote
queues are supported in this scenario.

| MSMQ messages do not go to the dead-letter queue by default, you need to
ask for for it.
If you send the messages using System.Messaging, use the following:
MessageQueue queue = new MessageQueue(@"....");
Message msg = new Message("test");
msg.Label = "some label";
msg.Body = "body";
msg.UseDeadLetterQueue = true;
If you are using MSMQ com objects, set the Journal property of the
MSMQMessage to MQMSG_DEADLETTER.

| Not sure I understand your response, Tim.
MSMQT does connect to a queue. How would you send a message to MSMQT
without a queue (albeit a remote one)?

| Hi Nick,
I can confirm that when you are submitting messages to BizTalk using MSMQT you do not create a queue, quote from the documentation:
"a queue in BizTalk Message Queuing is a virtual entity" (see Help ms-help://BTS_2004/Operations/htm/ebiz_ops_adapt_file_doxf.htm). What happens is that MSMQT listens on the standard MSMQ port and intercepts any messages that are destined for queues that
are defined as MSMQT receive locations and submits them into the Message Box. That's why you can't see the queues or the messages in the MSMQ explorer. I have not tried creating an MSMQ queue with the same name as an MSMQT receive location queue, but I
don't think the results will be very pretty!
When sending from BizTalk using MSMQT you do need a really MSMQ queue to post to and this must be a remote queue. I'm not sure if this is documented, but it took me a long time to figure this out and it has been confirmed by an on-site MS consultant.
I think the reason you have the vanishing message in HAT is that as far as BizTalk is concerned it didn't receive the message because of the clash of transaction support
