Resource manager can proxies use the IDtcToXaHelper 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.

This interface differs from the IDtcToXaSinglePipeHelper interface in that it requires that the resource manager proxy developer explicitly use the IResourceManager interface.

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.
