An object-based approach to implementing distributed concurrency control

Steven S. Popovich, Shyhtsun Felix Wu, Gail E. Kaiser

Abstract: Distributed concurrency control has been implemented by representing in-progress transactions as simulated objects, called transaction objects, that use normal message passing facilities. The implementation of an optimistic mechanism has been completed using transaction objects and a two-phase locking mechanism has been designed. The tradeoffs made and lessons learned, dealing with transactions both on objects and as objects, are discussed.<>
