摘要: This paper describes two efficient distributed transaction commit protocols, the Presumed Abort (PA) and Commit (PC) which have been implemented in data base system R* [DSHLM82, LHMWY83]. PA PC are extensions of well-known two-phase (2P) protocol [Gray78, Lamp80, LSGGL80]. is optimized for read-only transactions a class multi-site update transactions, other classes transactions. The optimizations result reduced inter-site message traffic log writes, and, consequently, better response time such We derive new protocols step-wise fashion by modifying 2P protocol.
