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.
Either call the DtcGetTransactionManager function with a riid of IID_IDtcToXaHelperFactory when initially connecting to DTC or call QueryInterface on any interface on the DTC proxy core object with a riid of IID_IDtcToXaHelperFactory.
