Title: INFERRED DETECTION OF DATA REPLICATION ERRORS OF SOURCE APPLICATIONS BY ENTERPRISE APPLICATIONS
Abstract:
This disclosure provides an apparatus and method for inferred detection of data replication errors of source applications by enterprise applications, including but not limited to in industrial control systems and other systems. A method includes periodically generating and storing (302) a heartbeat data value by a site risk manager (RM) system (202). The method includes sending site data with the current heartbeat data value (304) by the site RM system (202) to an enterprise application (214) executing on an enterprise RM system (212). The enterprise RM system (212) periodically compares (308) a current time and the last received heartbeat data value to produce a calculated time difference. The enterprise RM system (212) determines that site data replication is not functioning correctly (310) when the calculated time difference is greater than a predefined threshold. When the replication is not functioning correctly, the enterprise RM system (212) notifies a user (312) that replicated site data may be inaccurate.
