摘要： A database management system ensures consistency between primary and mirrored backup copies of a database, despite occurrence of a suspending condition interrupting the normal process of mirroring the primary database. One or more primary controllers are provided, each having a data storage unit with multiple primary data storage devices. Multiple secondary controllers each have multiple associated secondary data storage devices, each secondary controller being coupled to one primary controller. One or more primary databases reside on the primary devices, with a corresponding number of secondary databases residing on the secondary devices. Each secondary database mirrors a corresponding primary database. Either a host, attached to a primary controller, or one of the primary controllers itself, maintains a map cross-referencing each primary and secondary database with the primary and secondary devices containing portions thereof. If a predefined “suspending condition” affecting data mirroring occurs, the host or primary controller consults its map to identify all primary and secondary devices affected by the condition. Then, each primary controller stops all ongoing and future read/writes with each of its affected primary devices. Each primary controller also directs each secondary controller having an affected secondary device to stop mirroring the primary databases stored on that device. Then, the primary controller starts intermediate change recording and resumes read/writes with its primary devices. When the suspending condition ends, each primary controller applies the appropriate logged changes to its secondary database(s) and then reactivates each secondary database.
摘要翻译：数据库管理系统确保数据库的主镜像和镜像备份副本之间的一致性，尽管发生暂停条件中断镜像主数据库的正常进程。提供一个或多个主要控制器，每个主控制器具有具有多个主要数据存储设备的数据存储单元。多个次级控制器各自具有多个相关联的辅助数据存储设备，每个辅助控制器耦合到一个主控制器。一个或多个主数据库驻留在主设备上，相应数量的辅助数据库驻留在辅助设备上。每个辅助数据库镜像相应的主数据库。连接到主控制器的主机或主控制器本身之一的主机维护一个交叉参考每个主数据库和辅助数据库的映射，其中主要和次要设备包含其部分。如果发生影响数据镜像的预定义的“暂停条件”，则主机或主控制器将查看其映射，以识别受该条件影响的所有主设备和辅助设备。然后，每个主控制器将停止其每个受影响的主设备的所有正在进行的和将来的读/写。每个主控制器还指示具有受影响的辅助设备的每个辅助控制器停止镜像存储在该设备上的主数据库。然后，主控制器启动中间更改记录，并恢复其主要设备的读/写。当暂停条件结束时，每个主控制器将适当的记录更改应用到其辅助数据库，然后重新激活每个辅助数据库。
