[!INCLUDE SQL Server - ASDB] Use the DTCTransaction event class to monitor the state of [!INCLUDEssDEnoversion] transactions coordinated through [!INCLUDEmsCoName] Distributed Transaction Coordinator (DTC). This includes transactions involving two or more databases in the same instance of the [!INCLUDEssDE], or distributed transactions involving two or more instances of the [!INCLUDEssDE].
| Data column name | Data type | Description | Column ID | Filterable |
|---|---|---|---|---|
| ApplicationName | nvarchar | Name of the client application that created the connection to an instance of [!INCLUDEssNoVersion]. 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. [!INCLUDEssSqlProfiler] 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 [!INCLUDEssNoVersion] security login or the [!INCLUDEmsCoName] 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 [!INCLUDEssNoVersion] being traced. | 26 | No |
| SessionLoginName | nvarchar | Login name of the user who originated the session. For example, if you connect to [!INCLUDEssNoVersion] using Login1 and execute a statement as Login2, SessionLoginName shows Login1 and LoginName shows Login2. This column displays both [!INCLUDEssNoVersion] 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 |
