Abstract :
This paper describes transaction modeling and transactional recovery mechanism in Next Generation Trading System of Shanghai Stock Exchange. Stock trading systems belong to transactional information systems and require high performance and high availability. Firstly, a transaction model for stock trading is defined by a formal language. Secondly, a transactional audit model is proposed to support failover and restart scenarios of processes and hosts. Thirdly, several technologies in practice for performance enhancement are introduced, such as batch order processing, dual process switching, cache frame and audit index file, which extend the transaction model. This paper enriches the applications of transactional information system model and provides reference for architecture designers on enterprise systems with intensive transactions.
