Symptoms
Consider the following scenario:
-
You run Distributed Transaction Coordinator (DTC) transactions in Microsoft SQL Server 2017.
-
A transaction is started, and SQL Server successfully prepares the transaction.
-
A transaction commit request is sent to SQL Server.
-
The database that is involved in the transaction is restarted.
In this scenario, the transaction commit request from DTC fails because the database restarted. However, in some cases, SQL Server communicates to DTC that the transaction commit request was successful even though the request failed.
Resolution
This fix is included in Cumulative Update 1 for SQL Server 2017.
