4 Protocol Examples

The following sections describe several examples of common scenarios to illustrate the function of the MSDTC Connection Manager: OleTx Transaction Protocol Logical Unit Mainframe Extension. These protocol examples assume that an OleTx transports session (as specified in [MS-CMPO]) has already been established between the two participants.

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 to the underlying OleTx multiplexing layer, as specified in [MS-CMP] section 2.2.2.
