集群缓存服务器和光盘库的通信实现

Implementation of Communication Between Cluster-based Cache Server and CD Jukebox

针对光盘库文件被客户大量访问的特点,在光盘库前端加入集群代理缓存服务器。使用数据库服务器作为光盘库和缓存服务器的通信中介,选择合适的数据库软件MySQL,建立合乎要求的关联表,用MySQL自带的函数和SQL语言编写程序实现和数据库、机械手的通信。

To meet the demand of mass visit by clients, this paper sets cluster-based cache servers before CD jukebox. Database server is selected properly to be the communication agency between the cluster cache server and CD jukebox. Then it chooses MySQL as the best database software and sets up the associated tables according to the requests. The program which is written with the functions provided by MySQL and SQL carries out the communication with the database server and machine hand.
