ON-LINE SYNCHRONOUS SCHEDULE RECOVERY SYSTEM AND PROCESSING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To solve the following conventional problem related to a management method of a synchronous schedule processed from a plurality of on-line systems and synchronous recovery processing technology: when there is not transmission/reception history information of a synchronous command, a schedule state becoming inconsistent cannot be recovered.

SOLUTION: This on-line synchronous schedule recovery system comprises: a schedule information requirement part 210 requiring schedule information transmission of another on-line system; a schedule information notification part 220 notifying the other on-line system of schedule information; and a schedule synchronization recovery part 240 recovering synchronization of a schedule becoming inconsistent from command processing position comparison with another on-line.
