Patent number: 10831741Abstract: Techniques for data replication from a primary system to a standby system. A first buffer portion of a transaction log buffer is allocated to a first transaction at a primary system. Upon determining that the first buffer portion is fully formed, before the log data is written to the storage on the primary system, and before the transaction log buffer is entirely full, the log data in the first buffer portion is transmitted to the standby system, from the primary system. Upon writing the log data to the storage on the primary system and after the log data in the first buffer portion is transmitted to the standby system, a notification is transmitted to the standby system, from the primary system, where the standby system is configured to process the received log data responsive to receiving the notification from the primary system.Type: GrantFiled: December 4, 2017Date of Patent: November 10, 2020Assignee: International Business Machines CorporationInventors: Xun Xue, Steven R.
