| 1. | However , the farther analysis in the paper indicates that the strategy of parameter configuration in current connection pool technique is static state with 1 - order enactment while initializes connection pool without self - optimized adjustment according as the variety of application demand , the operation results of high use frequency database are not cached and users visit the same database independently . the multi - propose connection strategy cannot control the database operation for the same transaction and cannot ensure the acid attribute , etc . in according with the defections mentioned above , the service technique of self - optimized connection pool is presented in this paper and the composing structure for self - optimized connection pool is designed , then , some strategy in dynamic parameters adjustment , transaction management and data cache for connection pool is improved 然而,通过本文的研究分析,现有数据库连接池技术的参数配置策略是静态的,连接池初始化时进行一次设定,不能根据应用需求的变化而动态调整;连接池的核心管理机制中,没有对使用频率较高的数据库操作结果进行缓存,多个用户依然各自独立地完成相同的数据库访问;使用的连接复用策略无法控制属于同一个事务的多个数据库操作,不能保证事务的acid属性等。 |
