| 摘 要： | 针对常规数据库连接池由于参数静态设置所致适应能力较弱及可扩展性较差等问题,提出和设计了管家式自适应数据库连接池方案。该方案的管家方式以单例模式和双向链表为基础,通过引入日志动态分析策略和对数据库连接的预建方式,实现了数据库连接池的自适应。在云南小水电系统的应用表明,该方案比常规连接池更为高效实用。

| Abstract: | A self-adaptive scheme on database connection pool in a stewardship way is proposed in this paper because of the poor adaptability and scalability of normal database connection pool which are caused by parameters' static setting. Based on singleton pattern and doubly linked list, the scheme realizes its self-adaptation by adopting the strategy of log dynamic analysis and pre-built method of database connection. The application in small hydropower system in Yunnan power grid shows that the scheme is more efficient and practical than normal connection pool. |
