Problem(Abstract) |
When using XA data source to connect to SQL Server 2000,
running on Windows® 2003, you receive the following exception:
"java.sql.SQLException: [IBM][SQLServer JDBC Driver][SQLServer]xa_open (0)
returns -3" |
|
|
|
Cause |
Microsoft® Windows Server 2003, Microsoft Distributed
Transaction Coordinator (MS DTC) requires the creation of registry values
for all XA DLLs that you plan to use.
XA transactions are disabled by default on Windows Server 2003.
You might see the following exceptions in WebSphere Application Server
SystemOut.log:

Resolving the
problem |
Connect JDBC Drivers (DataDirect Connect JDBC, IBM®
WebSphere® embedded Connect JDBC) have the XA DLL sqljdbc.dll
that is normally installed on
SQLServer_Install_Root\MSSQL\Binn; for example:
c:\Program Files\Microsoft SQL Server\MSSQL\Binn). The registry
values required for XA transactions are not created automatically. You
must create the values manually as follows:
- Turn on support for XA transactions:
- Open Component Services.
- Expand the tree view to locate the computer where you want to turn on
support for XA transactions; for example, My Computer.
- Right-click the computer name, then click Properties.
- Click the MSDTC tab, then click Security Configuration.
- Under Security Settings, click the check box for XA Transactions to
turn on this support.
- Click OK, then click OK again.
- Create a registry named-value:
- Use Registry Editor and navigate to registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\XADLL
- Create a new registry named-value:
Name is the file name of the XA DLL (in the format dllname.dll)
Type is String (REG_SZ)
Value is the full path name (including the file name) of the DLL
file
Name |
Type |
Value |
sqljdbc.dll |
String (REG_SZ) |
c:\Program Files\Microsoft SQL
Server\MSSQL\Binn\sqljdbc.dll |
Note: You must create an entry for each XA DLL file that you plan to
use. Also, if you are configuring MS DTC on a cluster, you must create
these registry entries on each node in the cluster.
For more details, see the following Microsoft document:
INFO:
Registry Entries Are Required for XA Transaction Support |
