Abstract: PURPOSE: A method for controlling duplication of distribution main memory database is provided to maintain a consistency with respect to duplicate data and increase a reading availability thereof. CONSTITUTION: It is checked whether a reading transaction with respect to 'A','B','C' data items is generated(401) and all locks are obtained(402). If all locks are not obtained, it is checked whether a copy is a primary copy(403). If the copy is not a primary copy, it is checked whether a secondary copy is the latest version(409). If a secondary copy is the latest version, a shared lock is requested(410). It is checked whether the lock is successful(411). If the lock is not successful, a delay is processed(412) and it is checked whether all locks are obtained(402). If a secondary copy is not the latest version, a lock request is transmitted and a lock is waited(413). It is checked whether lock acquisitions from all primary copies are successful(414). If the lock acquisitions are successful, a transmission is prepared(416). The preparation is checked(417) and the transmission is completed(418), and the completion is checked to all primary copies(419).
Abstract translation: 目的：提供一种用于控制分配主存储器数据库的重复的方法，以保持与重复数据的一致性并增加其读取可用性。 构成：检查是否生成关于“A”，“B”，“C”数据项的读取事务（401），并获得所有锁（402）。 如果没有获得所有锁，则检查副本是否是主副本（403）。 如果副本不是主副本，则检查副本是否是最新版本（409）。 如果辅助副本是最新版本，则请求共享锁（410）。 检查锁是否成功（411）。 如果锁不成功，则处理延迟（412），并检查是否获得所有锁（402）。 如果辅助副本不是最新版本，则发送锁定请求并等待锁定（413）。 检查所有主拷贝的锁获取是否成功（414）。 如果锁获取成功，则准备传输（416）。 检查准备（417），传输完成（418），并检查完成所有主拷贝（419）。
