The Research And Application Of ATS Server In Urban Rail Transit

In recent years, under the attention and efforts by the government, the CBTC system begans to appear in our country and develops rapidly, to alleviate the urban traffic pressure, and make great contribution to the development of the economy.Urban rail transit has the following advantages, such as:a fast speed, large capacity,punctuality,security,environmental protection, energy and land saving, as a result, more and more cities want to join in the rail transit.The development of our CBTC has experienced from introduction, digestion, absorption, to fully grasp the core technology, walking out of a characteristic of high-speed development road. With the speeding up of urbanization development in our country, the people more and more demand for the subway’s stability, security, accurate and efficient and put forward higher requirements for it.The efficient and stable operation of the CBTC system depends on the efficiency and stability of each subsystem, data support is the core of the system. ATS server provides the high availability and stable operation for the database platform. Therefore, the efficient, stable and safe for ATS server is the significant particularly important.This paper mainly on the basis of CBTC system, focus on high availability of ATS server platform to do some design and research. First, this paper briefly introduces the CBTC system and ATS server, starting from the storage, management, analysis and demand of database, the server platform is designed which built a real dual-system hot standby system, based on the requirement of high efficiency, safety and stability for ATS server. Aimed at the defects of the dual-system hot standby, we virtual a RAC experiment platform in the PC. we come up with three kinds of performance tuning on the basis of the further study of its principle and also analysis for optimal performance, come to the conclusion on the basis of the awr physical examination report...
