input queue duplication
|
|
| masoud bayan 2004-07-09, 3:32 pm |
| We have a strange problem with BizTalk input queue. Our application sends
events on different times to BizTalk but occasionally BizTalk process some
of these events twice. We checked BizTalk input queue and we found some
events twice at the exactly same time in input queue. Although we are sure
that our application sent them only once for some reason BizTalk receives
them twice. We use BizTalk Server Interchange Application for doing an
asynchronous submit (we use Interchange.Submit method).
Any advice is welcomed.

| I assume "events" means "messages", right?
What BizTalk are you using, BizTalk 02 or BizTalk 04? Also, queue indicates
that the transport is either MSMQ or MQ SEries, right? Which one?
It's hard to tel anything without this information,

| Eldar thanks for you Reply.
BizTalk 2002
events=messages
We use BizTalk Server Interchange Application for doing an
that means that the client computer is calling the biztalk server using
BizTalk.Interchange COM component.
queue doesn't mean MSMQ or MQ Series. We spotted the duplicate messages in
InterchangeDTA database, tables dta_interchange_details and
dta_interchange_data, where BizTalk stores all its messsages.

| That's tough, I did not worked with it. From what you describe, the problem
is likely to be in the code calling the API for this COM component, unless
some exotic configuration is involved. If you have a preprocessor - it's
unlikely to result in such an effect because these APIs and code are widely
used/tested.
Hope somebody else seen that before and can help,
