Investigation And Design Of Transaction Processing Middleware

The distributed application system with the character of network and different environment is the result of the network as a whole and the parallel processing for the distributed tasks.Transaction middleware is a typical kind of the distributed On-line Transaction Processing,becoming a major platform of enterprise information system, which offers communication of striding platform, loading balance, fault-tolerant and resumable ability, and strengthens a new generation middleware in common with 3-layer architecture provided with the strong security, excellent management and high availability in common. Numerous distributed system,different database and different network environment are closely linked up among an enterprise, offering the function of mutual operation on application layer.The Open Group is an international open systems organization that is leading the way in creating the infrastructure needed for the development of network-centric computing and the information superhighway. Formed in 1996 by the merger of the X/Open Company and the Open Software Foundation, The Open Group is supported by most of the world's largest user organizations, information systems vendors and software suppliers. The X/Open Distributed Transaction Processing (DTP) model is a software architecture that allows multiple application programs to share resources provided by multiple resource managements, and provides international standard for distributed application.This paper discusses systematicly a series of concept, evolution,structure of Transaction Processing Middleware and localization of middleware argumentation at first. Then based on synthetically analyzing X/OPEN DTP model and investigating approxitate result inland and aboard, combining TCP/IP protocol,From angle of operation system, deep analyses and build an Transaction Processing Middleware,which belongs to DTP model standard,and applies to asynchronous, fallible network and heterogeneous platforms. Secondly, deep analyses on integrality, loading balance,communication efficiency and structure about Transaction Processing Middleware are made in this paper,and combining the practical application, thebold transformation and optimization to technologies is separately carried on, which enhances systematic function in various degrees to meet the demand.Finally, this paper evaluates shortage of Transaction Processing Middleware,and prospects development trends of Transaction Processing Middleware in the future.
