Abstract:
1. A method for synchronizing database files of a central node with database files of a local node in a network, wherein the central node is coupled to the local node via a communication link, the method comprising: initiating a monitoring signal to monitor the communication link between the central node and the local node for reestablishing the communication link therebetween responsive to a determination that the communication link is performing incorrectly, the monitoring signal being a periodic heartbeat signal which includes an initial signal from the central node to the local node and a corresponding return signal from the local node to the central node, wherein information indicative of the central node database files are incrementally included with sequential heartbeat signals such that each heartbeat includes information representing a different file; integrating information indicative of the files of the central node database with the monitoring signal; determining whether the files integrated with the monitoring signal corresponds with files of the local node database via indications in the monitoring signal; and generating a report including those central node database files determined not to correspond with a file of the local database.
