基于中间件的潜艇作战系统数据库访问技术

在分析国外典型潜艇作战系统体系结构的基础上,针对基于VxWorks的嵌入式应用系统访问Oracle数据库问题,提出了一种基于中间件的跨平台数据库访问方案,解决了分布式异构系统下多用户并发访问数据库的问题;设计开发了基于CORBA的数据库访问中间件,并对中间件的实时性、并发性进行了测试。测试表明:该方案可以解决嵌入式应用系统对Oracle数据库的跨平台访问,并且性能指标满足应用需求。

Technology of Database Access in Submarine Combat System Based on Middleware

Analyzing the architecture of foreign typical submarine combat system. In view of the difficulty of accessing Oracle database in embedded real-time environment based on VxWorks, the paper puts forward a method based on middleware to solve the problem. It supports general query database cross platform, and can concurrently respond multi-client requires in heterogeneous distributed system. The access database middleware based on CORBA has been designed, and its real-time performance and concurrentness testing have been done. The results show that the middleware above is feasible with the solution of the problem.
