CHANGED DATA TRACING METHOD IN ELECTRONIC EXCHANGE

摘要

The change information is output to an external terminal automatically when main data of an electronic exchange is changed. The method comprises the steps of: (a) checking a man machine communication data and generating an inter-processor communication message; (b) sending the message to a corresponding processor; (c) sending the message to a data base management system block of an object processor when the message is valid; (c) registering or removing the data to be traced from a table according to the message; (d) increasing or decreasing a trace variable; (e) checking the trace variable at every data change and sending the change information to a corresponding processor when the trace variable is not zero; and (f) generating an error message when an error occurs at every step.
