Abstract
본 발명의 목적은 교환기 백업 기능 조건에 만족되도록 데이타의 일치성 보장 및 빠른 속도를 갖는 실시간 DBMS에서의 백업 기능 구현 방법을 제공하는데 있는 것으로, 응용 프로그램내의 백업 릴레이션 변경 요구에 따라 메모리 DB변경후 디스크 백업을 위해 필요한 변경버퍼에 변경 내용을 기록하는 제1단계와, 상기 변경 버퍼를 기반으로 디스크에 적용하는 형태인 로그를 제작하는 제2단계와, 상기 제작된 로그를 전송 받아 로그 저장장소인 로프 스풀에 저장하는 제3단계와, 전송받은 로그를 저장하는 로그 스풀안에 로그의 존재 유무를 판단하여 로그가 존재하는 경우 디스크에 백업하는 제4단계와, 중복릴레이션의 변경요구인 경우에는 신속한 처리를 위해 마스터 프로세서에만 백업이 되게하고 타 프로세서들에게는 백업이 되지 않도록 하는 제5단계와, 시스템 재시동인 경우에는 중복 릴레이션 데이타의 일치를 위해 마스터 프로세서의 데이타 베이스(DB)내의 중복 릴레이션을 타 프로세서의 DB내 해당 중복 릴레이션 위치에 복사하는 제6단계를 구비한다.It is an object of the present invention to provide a method of implementing a backup function in a real-time DBMS that guarantees the consistency of data and has a high speed so as to satisfy a switch backup function condition. A first step of recording changes in a change buffer necessary for backup; a second step of producing a log in a form of applying to a disk based on the change buffer; and a rope storing a log as a log storage location by receiving the produced log The third step of storing the log on the spool, the fourth step of backing up the disk if the log exists by judging the existence of the log in the log spool storing the received log, and the rapid processing in the case of a request for changing the redundancy. 5th stage to make backup only to master processor and not to other processors And, in the case of system restart it has a sixth step of copying the DB within the overlapping relation to the location of the other processor overlapping relation in the database (DB) of the master processors for the matching of the overlapping relation data.
