Design And Implementation Of Uninterruptible Service Cluster System Based On Data Synchronization

Presently, in order to ensure the banking system processing capability and reliability, the domestic commercial bank widely used the core system of IBM mainframe technology to construct the core system. With the growth in use of time and the increasing of business, many problems of IBM mainframe technology expose including inflexibility, closure, high cost of operation and maintain and so on, while the monopoly status of IBM mainframe technology becomes more and more obvious. With the rapid development of information technology and the deeply research of removing "IOE"(removing IBM minicomputer, Oracle database and EMC storage device, replaced by self development system basing on open source software), the major commercial banks are trying to adopt open platform to construct high reliability cluster system which can improve the system flexibility, reduce the cost of system construction, operation and maintenance, gradually replace the monopoly status of1IBM mainframe technology.This thesis mainly solves the technical monopoly problems of IBM mainframe technology in banking system, adopting open platform to construct the cluster system with high reliability performance, constructing bank business processing system. The main work includes:1. Deeply analysing the channel management platforma of a large domestic commercial bank, determing the minimum data synchronization time and the core technology platform to construct the "double active"("double active" is the abbreviation of the most advanced disaster recovery).2. Fully consider the flexibility, versatility and high efficiency, adopting cluster architecture design to construct a real time trade system which can provide7*24hours uninterrupted service and support a large quantity of concurrent operation.3. Achieve data synchronization on the base of message oriented middleware EMS(Express Messages Service, TIBCO ESB message oriented middleware),and ensure the "double active" of cluster system".4. Achieve system load balancing and continuous service basing on F5load balancer.The design and implementation of channel management platform in this thesis has been put into practical use. This platform is designed based on cluster architecture, which can achieve uninterrupted service of concurrent business. Since the platform puting.into operation, the platform is stable and reliable. According to the statistics of Chinese UnionPay, the interbank transaction success rate of this bank is among the fifteen commercial banks highest, which achieving the desired goals. The completion of the platform, has laid a solid foundation for achieving the mainframe replaced by minicomputer cluster technology.
