BUG #: 406357 (SQLBUDT)



Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.



SYMPTOMS
When you run a package that calls other child packages in Microsoft SQL Server 2005 Integration Services (SSIS), one or more of the child packages may fail. Additionally, you may receive the following error message:

Error: 2005-09-06 15:07:47.14

Code: 0xC001402C

Source: @PR018_SS8PR032 Connection manager &quot;ETC&quot;

Description: The SSIS Runtime has failed to enlist the OLE DB connection in a distributed transaction with error 0x8004D00A &quot;Unable to enlist in the transaction.&quot;.

End Error

This problem occurs when the following conditions are true:
 * The TransactionOption property is set to the Required value.
 * You use the Microsoft OLE DB Provider for SQL Server on the source database and on the destination database. The databases are on the same server computer.
 * The Microsoft Distributed Transaction Coordinator (MS DTC) service is enabled.



CAUSE
This problem occurs because only one request can own a transaction at a time. Therefore, when a transaction enlistment request occurs on the specific transaction that is running, the transaction enlistment fails.



Service pack information
To resolve this problem, obtain the latest service pack for SQL Server 2005. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

913089 How to obtain the latest service pack for SQL Server 2005



WORKAROUND
To work around this problem, you can rely on implicit transaction management and set the TransactionOption property to the Supported value.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section. This problem was first corrected in SQL Server 2005 Service Pack 1.



MORE INFORMATION
The scope of the fix is the Data Flow task level. If you have multiple Data Flow tasks that will join a distributed transaction, you may still encounter the error described in the Symptoms section. After you install the hotfix or SQL Server 2005 Service Pack 1, you can avoid the problem and use the fix by moving these connections and tasks that are spread across multiple data flow tasks into a single data flow task. This hotfix will still use parallel execution and avoid the problem. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
