A concurrent control mechanism based on OO in collaborative design 协同设计中基于面向对象方法的并发操作控制机制
Lotus Domino/ Notes is an excellent GroupWare System which is widely used in developing OA systems. But the concurrent control mechanism of the Domino Database can not satisfy the requirements of applications. LotusDomino/Notes是当今比较优秀的群件系统,广泛运用于OA系统的开发,但Domino数据库对事务并发操作的处理机制不能满足开发应用的要求。
Special emphasis is put on the management of field directory, the concurrent control mechanism and the two-phase-submit protocal which ensures the consistency of multiple copy data. 文章着重讨论了文件目录和管理,并发控制机构以及为保证多付本数据一致性的两步提交协议。
The related performance index and judging methods are given, and the general concurrent redundancy control mechanism is designed based on Producer/ Consumer model. 给出了CCRP相关性能指标和判断方法,基于生产者/消费者模型提出了通用并发重复控制机制。
