In a Microsoft Host Integration Server 2010 environment, you configure a Transaction Integrator (TI) application to use the 2 Phase Commit (2PC) protocol. When you use the application for distributed transaction, the application does not enlist a transaction with the Microsoft Distributed Transaction Coordinator service (MSDTC). Additionally, you may receive the following exception:
The SNATransport, when processing method method-name, has failed when attempting to enlist in a transaction. Ensure that the remote LU name LU-name is configured to EnableSyncPoint.
