Hi all,

I am having a problem figuring out error handling with my serviced component. I am reading data from the database and I get deadlock errors. To solve deadlock, i catch that error and resubmit it and i get following error: "Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction." Any idea what i can do here? it seems like that the transaction is setting to complete. I have added code to disable setcomplete but it still doesnt work. Here is the psuedo code for what i am doing:

private sub GetData(...)

Try
GetDatafromDb()
Catch ex
if error = deadlock then
ContextUtil.DisableCommit()
GetData (resubmit)
else
throw ex
End If

End Try

End sub

Please let me know what I am doing wrong. Thank you.

Hi Arpan,

It looks like your database is aborting the transaction when it detects the
deadlock. Setting DisableCommit will not help. You need to bubble up the
error outside the layer that started the transaction. You can't do any
database work as part of this doomed transaction.

Regards,
