FIX: SQL Server Does Not Properly Inform the DTC of Aborted Transactions (248492)



The information in this article applies to:

  • Microsoft SQL Server 7.0

This article was previously published under Q248492
BUG #: 56751 (SQLBUG_70)

SYMPTOMS

Under some circumstances when using the Distributed Transaction Coordinator (DTC), a transaction may be aborted on one server yet committed on another. This can happen if a situation such as the following example exists:

Consider two servers, A and B. A transaction starts on Server A and uses DTC to call a stored procedure on Server B. If a transaction abort happens on Server B (for example, a deadlock occurs), it returns the error message to Server A, but does not tell DTC to abort the transaction. As a result, Server A commits the transaction when it should have aborted it, because it was aborted on Server B.

CAUSE

Under some circumstances SQL Server is not passing a transaction abort to DTC.

WORKAROUND

To work around this problem, the application must interpret the incoming error message and manage the transaction itself rather then relying on DTC to abort the transaction.

STATUS

Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
