4 Protocol Examples
The following sections describe several examples of common scenarios to illustrate the function of the MSDTC Connection Manager: OleTx XA Transaction Protocol Extension. These protocol examples assume that an OleTx transports session, as specified in [MS-CMPO], has already been established between the two participants.
In these examples, the abbreviation "gtrid" is used for "XA Global Transaction Identifier" to conserve space.
Participants communicate with each other using OleTx multiplexing connections (as specified in [MS-CMP]) that are in turn layered on top of the OleTx transports infrastructure (as specified in [MS-CMPO]). In these examples, messages are sent from one participant to another by submitting a MESSAGE_PACKET (section 18.104.22.168) to the underlying OleTx multiplexing layer, as specified in [MS-CMP].
