Resource manager proxies can use the IDtcToXaHelperFactory interface to map between OLE Transactions and XA protocol when the XA is being used as the native protocol for distributed transactions. ODBC is an example of an RM proxy. The following sections use ODBC as a specific example to facilitate the understanding of what needs to be done in the resource manager proxy to map OLE Transaction to the XA protocol.
When to Implement
You do not need to implement this interface. It is implemented by the core object of the DTC Proxy.
When to Use
Use this interface to map between OLE Transactions and the XA protocol using the one-pipe connection model.
