Securities Firms Trading System "homogeneity" Research Of Fault

Now the centralized transaction system which is the core business system of the security market participants uses the "main system, backup system, disaster recovery" recovery system based on redundant mechanisms; homologous, isomorphic with the structure of "no single point of failure". It’s the primary principle of safe operation in centralized transaction system of the security companies. Focus from the design of system,it has dealt with the issues of hardware, network and applications, but there is no publicly accepted solution to the design of "no single point of failure" for operations system, database and all app. Therefore the current disaster recovery system has no feasible fault-tolerance approach to the problems caused by the software code.The subject is to get the preliminary solutions to single point of homologous failure caused by the potential software code problems from the application system, operation system and core database of current recovery system for centralized transaction system in domestic security industry. Therefore, building the isomerization disaster recovery system for the centralized transaction system becomes the approach to solve the single point of homologous failure from the homology and isomorphism. To set up centralized transaction system by heterogeneous method, could be an approach to implement the system of the industry and an expansion of currently recovery system with mechanisms of hardware redundancy and deployment redundancy.The proposition of heterogeneous disaster recovery system consists of two parts, order processing issue and order form issue:●Order process system issue1. Adopting heterogeneous disaster recovery system which is different from existing main production system, to build order processing system.2. Simplifying the order process system binding to the accepted principals to lower the complexity of business logic in the heterogeneous system and to ensure continuity of the core real-time bidding business.3. Applying the Shanghai Stock Exchange’s EzOes and Shenzhen Stock Exchange’s dbf interface library declaration/return real-time data recovery mechanisms, and financial transactions data recovery mechanism by third-party depository RMB interfaces, to reduce the data exchange complexity between heterogeneous systems, and to achieve data consistency of capital and shares.●Order generation system issues 1. The trading platform consisting of several sets of heterogeneous trading system by technical means is transparent and seamless for end-user. It can automatically switch when one of the terminals breaks down with fatal error.2. Tracking and maintaining different order generating systems at the client terminal by setting the software module steward of trading platform to reach the goal of centralized administration and intelligence upgrade.As the proposition of heterogeneous disaster recovery system applies the recovery design of real time data from the standard interface of shanghai stock exchange and bank, it significantly reduces structure complexity, enables the heterogeneous expansion of the current homology and isomorphism disaster recovery system, and immunes the integrated transaction system from single point of homologous failure.Referring to the specific design proposal and example of prototype systems, heterogeneous disaster recovery system can guarantee the centralized transaction system to continue its core business function and to void the disastrous impact from single point of homologous failure.
