  • Method for validating transactions in a system that includes indeterministic ordering of change log events by using deterministic indicia
    Patent number: 11768822
    Abstract: A method is provided for validating transactions in a system that includes indeterministic ordering of change log events by using deterministic indicia. The system includes a plurality of nodes. Each node in the system includes an instance of a database used by an application, and a change log associated with the instance of the database used by the application. Each node executes transactions. Each transaction includes one or more data manipulation language (DML) or data definition language (DDL) operations. Results of the DML or DDL, operations are stored in the change log as change log events, wherein the order of the change log events stored in the change log on one node is in a different order than the order of change log events stored in the change log of at least one of the other nodes. For each transaction executing at each node, deterministic subunits of the change log events are defined. Indicia are then computed for each subunit of the change log events.

  • Methods for repairing a corrupted database to a new, correct state
    Patent number: 9830223
    Abstract: A corrupted database is returned to a correct state by rolling forward or backward through a change queue and applying changes to the database in a selective manner. Changes that did not cause the corruption are applied without modification when rolling forward or are skipped when rolling backward. Changes that caused corruption are addressed when rolling forward, such as by being ignored or modified and then applied. Changes that caused corruption are corrected when rolling backward.

  • Methods for returning a corrupted database to a known, correct state
    Patent number: 8903779
    Abstract: A corrupted database is returned to a correct state by rolling forward or backward through a change queue and applying changes to the database in a selective manner. Changes that did not cause the corruption are applied without modification when rolling forward or are skipped when rolling backward. Changes that caused corruption are addressed when rolling forward, such as by being ignored or modified and then applied. Changes that caused corruption are corrected when rolling backward.
