Abstract: A system and a method for keeping two versions of a mirrored database in sync is provided. A connection is monitored between a primary database and a secondary database. When a loss of the connection between the primary database and the secondary database is detected, the primary database is monitored for changes. When a modification is detected to at least one row in the primary database, a value of a change indicator is changed for the corresponding row indicating that the row was modified. Once the connection between the primary and the secondary databases is restored, the primary database is queried for the value of the change indicator indicating the corresponding row was modified to obtain a current value for data in the corresponding row of the primary database, and the corresponding row in the secondary database is updated with the current value for the corresponding row.
