Title:
DISTRIBUTED CHECK POINT GENERATION METHOD AND COMPUTER SYSTEM TO WHICH THE METHOD IS APPLIED
Document Type and Number:
Japanese Patent JP3154942
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To generate the distributed check points of plural processes executing inter-process communication and to shorten process stop time accompanying the generation of the distributed check points.
SOLUTION: Communication control parts 11 controlling inter-process communication and local check point generation parts 12 are provided for respective plural processes P1-Pn. The check points of the respective processes are generated after inter-process communication is stopped. Thus, the processes do not execute communication in the local check point setting timing of the processes P1 and P2, and the distributed check points can be generated in a state where consistency is held. Thus, the operation stop time of the whole processes can be shortened compared to a conventional case where the local check points are generated after all the processings of the related processes are synchronously stopped.
