    • A transaction is divided into a subset of a resumable unit and is transmitted when the transaction is performed in a single server and clustering database environment. The received transaction unit is rolled back in a reverse order of a unit when performing rollback due to a server failure. A point of detecting the transaction unit securing consistency is set as a resumable point and the rollback is stopped. Transaction information received up to a resumable point is reserved. Thereby, data transmission efficiency is improved by resuming the transaction after the resumable point without performing the transaction from the beginning again.

    • 事务分为可恢复单元的子集,并且在单个服务器和集群数据库环境中执行事务时传输。 由于服务器故障执行回滚,接收到的事务处理单元以单位的相反顺序回滚。 检测事务单元保护一致性的一点被设置为可恢复点,并且回滚停止。 保留到达可恢复点的事务信息。 因此,通过在可恢复点之后恢复事务而不再从开始执行事务来提高数据传输效率。 (102,152)通信单元; (104)单元成型单元; (108,158)控制单元; (110,160)存储单元; (116)缓存单元; (154)数据处理单元; (156)回收单位; (AA)通信网络
