MSDTC Dependencies tab.With the dependencies added you can bring the MSDTC service online. For this service to
failover correctly when you add additional nodes, you must also map MSDTC to a service.
This is done from the command line.To map MSDTC as a service, follow the next steps:- Open an elevated command prompt, and run MSDTC with the following switches:
■ (^) -tmMappingSet
■ (^) -name: “<any unique name is fi ne here, recommend DTC_SQLNetworkName>”
■ (^) -service: “<the actual service, for a default install this would be MSSQLSERVER;
otherwise it would be MSSQL$INSTANCENAME>”
■ (^) -ClusterResourceName: “
If the mapping is successful, another screen pops up stating Operation Succeeded.
Figure 29-13 illustrates the command line syntax and the result screen.
