The Two-Phase Commit (2PC) protocol allows an application program to update databases on multiple database management systems, ensuring data consistency on all systems involved. If an application runs in Two-phase commit mode, all the changes in a defined logical unit of work either commit or roll back. In a system set up to support Two-phase commit transactions, there must be a coordinator (such as CICS or IMS) and one or more participants (such as the Teradata server or IBM DB2).
