METHOD FOR PROCESSING DUPLICATED RELATION DURING BACKING UP IN EXCHANGE

摘要

PURPOSE: A method for processing a duplicated relation backing up in an exchange is provided to prevent the occurrence of disagreement of PLD(Programmable Logic Device) data in order to minimize the break off time of a system and exchange a version at the same time. CONSTITUTION: A method for processing a duplicated relation during backing up in an exchange is made to exchange the version using a standby loading function able to minimizing the break off time of the system, when applying a package backed up in an MT(Magnetic Tape) instead of a package being operated at present due to the obstacle during system operation. The method includes the processes of: inspecting whether a backup command is a PLD backup request signal; performing a duplicated relation processing by requesting the duplicated relation processing in the case of a PLD backup request signal; and performing backup by transporting the result of the duplicated relation processing.
