Abstract: Technologies are described for performing replication of data within a database environment having a source node and a replica node. The source node executes a database operation on at least one database table stored by the source node. The source node asynchronously sends the database operation to the replica node. A prepare commit request is synchronously sent from the source node to the replica node. The source node receives a synchronous precommit acknowledgement from the replica node. The precommit acknowledgement indicates that the database operation was executed at the replica node. The source node commits a transaction associated with the database operation.

Method and system for implementing from asynchronous copy to synchronous copy by data
Xiao Yang,Enhua Zhang,Guobin Zheng +2 more
- 18 Mar 2009
TL;DR: In this paper, a method for converting an asynchronous copy of data to a synchronous copy and a system is proposed, which mainly comprises the following steps: receiving requirements of the asynchronous copy by an asynchronous Copy Unit of a standby node, transmitting requests of the async-copy to the asynchronous Copy unit of a source node, submitting a journal to the standby node by the source node and judging the submitted journal of the submitted submitted journal in real-time and judging whether the deviation of the synchronous journal of a journal which is synchronized to the SU satisfies the appointed range of the system
