DTCTransaction Event Class
Applies to: 
SQL Server
Azure SQL Database
Use the DTCTransaction event class to monitor the state of SQL Server Database Engine transactions coordinated through Microsoft Distributed Transaction Coordinator (DTC). This includes transactions involving two or more databases in the same instance of the Database Engine, or distributed transactions involving two or more instances of the Database Engine.
DTCTransaction Event Class Data Columns
| Data column name | Data type | Description | Column ID | Filterable |
|---|---|---|---|---|
| ApplicationName | nvarchar | Name of the client application that created the connection to an instance of SQL Server. This column is populated with the values passed by the application rather than the displayed name of the program. | 10 | Yes |
| BinaryData | image | Binary representation of the Unit of Work ID (UOW) that uniquely identifies this transaction within DTC. | 2 | Yes |
| ClientProcessID | int | ID assigned by the host computer to the process where the client application is running. This data column is populated if the client provides the client process ID. | 9 | Yes |
| DatabaseID | int | ID of the database specified by the USE database statement or the default database if no USE database statement has been issued for a given instance. SQL Server Profiler displays the name of the database if the ServerName data column is captured in the trace and the server is available. Determine the value for a database by using the DB_ID function. | 3 | Yes |
| DatabaseName | nvarchar | Name of the database in which the user statement is running. | 35 | Yes |
| EventClass | int | Type of event = 19. | 27 | No |
| EventSequence | int | Sequence of a given event within the request. | 51 | No |
| EventSubClass | int | Type of event subclass. 0=Get address 1=Propagate Transaction 3=Close connection 6=Creating a new DTC transaction 7=Enlisting in a DTC transaction 9=Internal commit 10=Internal abort 14=Preparing Transaction 15=Transaction is prepared 16=Transaction is aborting 17=Transaction is committing 22=TM failed while in prepared state 23=Unknown |
21 | Yes |
| GroupID | int | ID of the workload group where the SQL Trace event fires. | 66 | Yes |
| HostName | nvarchar | Name of the computer on which the client is running. This data column is populated if the client provides the host name. To determine the host name, use the HOST_NAME function. | 8 | Yes |
| IntegerData | int | Isolation level of the transaction. | 25 | Yes |
| IsSystem | int | Indicates whether the event occurred on a system process or a user process. 1 = system, 0 = user. | 60 | Yes |
| LoginName | nvarchar | Name of the login of the user (either the SQL Server security login or the Microsoft Windows login credentials in the form of DOMAIN\username). | 11 | Yes |
| LoginSid | image | Security identification number (SID) of the logged-in user. You can find this information in the sys.server_principals catalog view. Each SID is unique for each login in the server. | 41 | Yes |
| NTDomainName | nvarchar | Windows domain to which the user belongs. | 7 | Yes |
| NTUserName | nvarchar | Windows user name. | 6 | Yes |
| RequestID | int | ID of the request containing the statement. | 49 | Yes |
| ServerName | nvarchar | Name of the instance of SQL Server being traced. | 26 | No |
| SessionLoginName | nvarchar | Login name of the user who originated the session. For example, if you connect to SQL Server using Login1 and execute a statement as Login2, SessionLoginName shows Login1 and LoginName shows Login2. This column displays both SQL Server and Windows logins. | 64 | Yes |
| SPID | int | ID of the session on which the event occurred. | 12 | Yes |
| StartTime | datetime | Time at which the event started, when available. | 14 | Yes |
| TextData | ntext | Textual representation of the UOW that uniquely identifies this transaction within DTC. | 1 | Yes |
| TransactionID | bigint | System-assigned ID of the transaction. | 4 | Yes |
| XactSequence | bigint | Token used to describe the current transaction. | 50 | Yes |
