METHOD FOR CORRECTING FUNCTION OF SYSTEM ON ONLINE STATE

摘要

PURPOSE: A method for correcting a function of a system on an online state is provided to add a new function, modify a corrected part, and delete an error part while not occurring or minimizing a system failure on the online state, and change/operate a memory without replacing a package during system operation. CONSTITUTION: An MCR(Memory Correction Recovery) extractor(21) extracts the MCR information by extracting a corrected address and the corrected particulars from a current source program and the corrected source program. An MCR editor(22) receives a memory correction request signal from the MCR extractor and performs an editing function. An MCR loader(23) corrects the memory by using the MCR input output from the MCR editor. The MCR loader checks a memory state, recognizes/starts a correction program, confirms the correction, and performs recording/backup of the correction particulars.
