1.3.1.2.3 One-Pipe Model

In this model, after an XA Resource Manager is enlisted in an OleTx transaction, an implementation-specific enlistment in the OleTx transaction makes the calls necessary for the Two-Phase Commit Protocol, using the XA Interface specified in [XOPEN-DTP], to the XA Resource Manager.

If a transient failure occurs and recovery is necessary, the XA Resource Manager Bridge Facet drives the recovery process with all registered XA Resource Managers.
