要: 提出一种自优化数据库连接池的设计方式。它可根据应用规模动态地调整设置参数, 进而选取对应的
管理策略, 其中策略可以存储在连接池的配置文件中或作为知识库保存。在对连接资源进行有效管理的同时,
可以对连接池的最大连接数与最大等待时间进行动态调整, 并在每次初始化时将优化的配置参数读入, 实现连
接池的自优化, 提高数据库运行效率。

Abstract: A new design approach on database connection pool, self-optimized connection pool, is proposed in the paper. By
using this method, connection pool can dynamic adjust configuration parameters and choose accordingly management strate-
gies, which can be stored in configuration file or repository. Furthermore, this paper has implemented a case about database
connection pool, which is of the function of adjusting preferences. The case of self-optimized connection pool improves greatly
the performance for connection pool as a result of loading the optimized configuration parameters when every initializing the
pool.
