Two-Phase Commit Terminology
A syncpoint tree is built by the coordinator of a unit of work. The syncpoint tree determines which process is in control of the commit/abort decision.
Each node in the syncpoint tree is the coordinator of its own resources and of the nodes below it on the syncpoint tree. Additionally, a node is a participant of the node directly above it in the syncpoint tree.
