  • Data replication system and method
    Patent number: 6304882
    Abstract: A data replication processing system includes a source database system and one or more target database systems all of which are coupled through a network. The replication processing system provides a replication protocol that allows for the source database and the target databases to remain consistent and in agreement. A method for the replication processing system includes having a target database request a refresh of its subset of the source database from the source database system. The source database system receives the refresh request message and constructs a refresh reply message that includes transactions from the source and the target. The target database system receives the refresh reply message from the source database system and applies the changes to its subset of the source database so that the two databases are in agreement with respect to their appropriate data sets.
