CONTROL AND COORDINATION OF HETEROGENEOUS TRANSACTION PROCESSING SYSTEMS

Transaction processing systems (TPS) applications are a large componen t of most business organizations' investment in computer technology. H eterogeneous and distributed computing environments have become essent ial and beneficial to most corporations. Thus, there is a need for too ls to support the development of new distributed TPSs and the migratio n of existing TPSs to distributed environments. This paper presents th e design and construction of a software tool that provides the functio nalities necessary for the construction, operation and management of h eterogenous distributed TPS applications. The tool design is based on object-orientation and real-time control and is implemented using Prol og and C. We anticipate that the tool will provide practical and signi ficant benefits to the operators and maintainers of large-scale TPSs.
