Abstract
A method includes reading, by a capture engine, log data. The log data can be synchronously hardware-replicated. The log data reflects that an update was started for a database of a first site. The capture engine corresponds to a capture engine of a second site. The method also includes identifying, by the capture engine, the update. The method also includes determining whether the update was committed to the database of the first site. The method also includes replicating, by an apply engine, the update to a database of the second site based on the determining. The update is replicated to the database of the second site based on a determination that the update was committed to the database of the first site. The committed update corresponds to a consistent replication of updates across two or more databases that reside in multiple database management systems.
