.NET and UDB2 Transaction Manager

[Yaro]

We are running on W2k3, DB2v8 Enterprise Srv, FP8.

On our server we have one DB2 instance and 2 databases.
On another stations we have .NET applications which use DB2 Connection, DB2
Command,....components. ADO.NET use OLE DB.NET Data Provider. We are
interesting how we can realize distributed transactions on two databases
(DB1 and DB2). We do not need Microsoft Transaction Server. We are
interesting rather DB2 Transaction Manager.

What we should do to realize that? What we shoud configure on the server
side, how we should write an application, what we should set in another
places? It is possible?

In a documentation I found only CLI examples. Can anyone help me?

Thanks
Yaro
