THE DESIGN AND THE IMPLEMENTATION OF A DOSTP- A DISTRIBUTED OBJECT ORIENTED SYSTEM BASED ON TRANSACTIONS PROCESSING

Abstract. This paper presents an experimental object oriented system that provides operating system level support for distributed transactions that operate on share objects. Transactions are a common construct that distributed programming environments provide in order to maintain the consistency of distributed information in the presence of partial failure and concurrency. The goal of constructing a transactions support in a distributed object oriented system is to make transactions available as a fundamental programming constructs for reliable distributed computing � on the other hand, the distributed environment can be used to exploit the parallelism in some computation within transactions. This paper presents the basic components of a distributed object oriented system based on transactions processing and its implementation on a local network of DEC Stations 3000 under OSF/1 vers 1.32 and Zenith PC under Linux 1.2.8 and on a NOVELL network under NetWare 3.11. Basic transport{level communication is performed by TCP/IP, UDP/IP via an Ethernet and by IPX, respectively. 1
