in-doubt xact resolution option changes the behavior of the default outcome for transactions that the Microsoft Distributed Transaction Coordinator (MS DTC) is unable to resolve. This helps prevent MS DTC–related downtime and provides clarity to transaction outcomes across database servers. A value of
1 is a presume commit directive. In other words, any MS DTC in-doubt transactions are presumed to have committed. A value of 2 is a presume abort directive, which means any MS DTC in-doubt transactions are presumed to have aborted.
The following is an example of this option:
exec sp_configure 'in-doubt xact resolution', 2goRECONFIGUREgo
