摘　　要：在分析现有数据库连接池方法的基础上,提出了一种基于ADO技术、能自适应调节的数据库连接池优化策略。策略中记录下每一个被调用的连接信息,通过管理模块分析这些信息,优化并动态配置连接池参数,达到连接池参数的自适应调整目的。测试结果表明,提出的连接池策略在处理并发请求的性能上明显优于现有数据库连接池方法。On the basis of the analysis of the existing database connection pooling method, a database connection pool optimiza- tion strategy which is baseed on ADO technology and can do self-adaptive is put forward. In this strategy, each called connection information will be recorded, and then these information is analyzed through management module, optimizing and dynamic con figure the parameters of connection pool, which can reach the purposes of self-adjusting. The test results show that this strategy of connection pool is obviously superior to the existing database connection pool in dealing with the performance of concurrent requests.
