Research On Quick Access In Database Of DTS

In this paper,data support platform supported by Oracle database is optimized in order to speed up the simulation in Dispatcher Training Simulator (DTS), which demand high real time requirement. In terms of inter-process communication, the shared memory, which can be wrote and read, is used to exchange a mass of data continually. We select the direct path load method of OCL to load the simulation data, through comparing several kinds of method between common database access technology and technology for Oracle only. And the OCL technology is improved in program, so as to it can suit the characteristic of data in DTS and speed up load simulation data. In terms of network of DTS, in order to reduce the redundancy in network, server thread, sending data to client on its own initiative, is presented, and the mode of communication in network is improved. At last, the Oracle database, which is optimized in physical structure and logic structure, reach its best performance in reading and writing.
