When the coordinator has received all the acknowledgements, the transaction is considered complete. The second possible path occurs if any of the transaction managers returned a Failure message in the Prepare phase. A single failure means that all the updates should be rolled back, so the transaction coordinator sends out an Abort request to the transaction managers. The managers perform a rollback of the updates under their control and send an acknowledgement to the coordinator. This is the basic flow through the two-phase commit process. Naturally, there are a number of other options.
