摘要： 分析了DB2分区数据库系统在典型的Shared-Nothing硬件环境中的请求处理机制,发现该系统在大量请求并同时访问同一数据库时其“目录节点”将成为系统的“瓶颈”,在原系统的基础上设计了一种新的系统体系结构框架,新的结构不仅可以解决原结构中存在的“瓶颈”问题,增强系统的处理能力,而且使系统配置更灵活,具有更强的扩展能力。

Abstract: Through analyzing the request process mechanism of the DB2 EEE in the typical shared-nothing architecture, it finds that found the catalog nodes would be bottlenecks of the system when massive request come. This paper presents a new parallel database system architecture based on DB2 EEE. The new architecture can remove bottlenecks of DB2 EEE and enhance performance of the database system, furthermore , it provides more flexible configure for the system . In addition, the new architecture has much power scalability.
