Configure MSDTC on SQL Server and adapter client
The operations performed on SQL Server using the SQL adapter (through BizTalk Server, the WCF service model, or the WCF channel model) can be performed within a transaction scope. If the client program has more than one transactional resource as part of the same transaction, the transaction gets elevated to an MSDTC transaction. To enable the adapter to perform operations within the scope of an MSDTC transaction, you must configure MSDTC both on the computer running the SQL adapter and SQL Server. Also, you must add MSDTC to the exceptions list of Windows Firewall. This section provides information about how to perform these tasks on computers running the adapter client and SQL Server.
Performing operations on SQL Server using BizTalk Server always involves two resources—the adapter connecting to SQL Server and the BizTalk Message Box residing on SQL Server. Hence, all operations performed using BizTalk Server are performed within the scope of an MSDTC transaction. So, to use the SQL adapter with BizTalk Server, you must always enable MSDTC.
For operations where the adapter client does not write any data to the SQL Server database, such as a Select operation, you might not want the additional overhead of performing the operations inside a transaction. In such cases, you can configure the SQL adapter to perform operations without a transactional context by setting the UseAmbientTransaction binding property to false. For more information about the binding property, see Read about the BizTalk Adapter for SQL Server adapter Binding Properties. In such cases, you do not need to configure MSDTC as well.
Open Component Services.
Or, In Server Manager, select Tools, and then select Component Services.
Expand Component Services, expand Computers, expand My Computer, expand Distributed Transaction Coordinator, right-click Local DTC, and select Properties.
Select the Security tab. In this tab, select all of the following:
- Network DTC Access
- Allow Remote Clients
- Allow Inbound
- Allow Outbound
- No Authentication Required
Select OK to save your changes.
If prompted to restart the MSDTC service, select Yes. After the MSDTC service is restarted, close the properties and the Component Services MMC.
Add MSDTC to Windows Firewall exceptions list
Microsoft Distributed Tansaction Coordinator (MSDTC) may already be allowed in your firewall. If so, it is listed as an Inbound Rule. If it's not listed, use this section to allow MSDTC.
Open Windows Firewall, and select Advanced Settings on the left.
Or, In Server Manager, select Tools, and then select Windows Firewall with Advanced Security.
Right click Inbound Rules, and select New Rule.
In the wizard:
- Select Program, and select Next.
- Set the program path to
%SystemRoot%\system32\msdtc.exe, and select Next.
- Allow the connection, and select Next.
- Select Domain, and select Next.
- Enter any name, such as
MSDTC for Oracle EBS, and select Finish.
Complete the wizard, and close Windows Firewall.
