제1도는 본 발명의 전전자 교환기의 DBMS의 데이타 베이스 백업 및 회복 기능 구조도, 제2도는 전전자 교환기의 DBMS에서 데이타 베이스 백업 및 회복 기능을 구현하기 위한 블럭간의 구성과 메세지 흐름 구성도.1 is a block diagram of the database backup and recovery function of the DBMS of the electronic switchgear of the present invention, and FIG. 2 is a block diagram and message flow diagram for implementing a database backup and recovery function of the DBMS of the electronic switchgear.

Claims (1)

전전자 교환기의 데이타 베이스 관리 시스템(DBMS)에서의 데이타 베이스 백업 및 회복하는 방법에 있어서, 응용 프로그램으로 부터 백업 데이타 변경 요구를 받아 변경 내용을 로그로 제작해 로그 화일에 저장하는 제1단계, 상기 제1단계후 백업 요구(운용자로 부터의 백업 요구, 로그 화일 크기의 임계치를 넘을때 백업요구, 및 회빈시일때 백업 요구)를 받으면 백업에 요구된 해당 로드 화일의 내용을 디스크에 있는 해당 데이타 베이스에 백업하는 제2단계, 상기 제2단계후 다운된 프로세서로부터 회복 요청을 받아 해당로그 화일에 대한 정보를 요구하는 제3단계, 상기 제3단계후 로그 화일에 있는 로드를 메모리에 있는 데이타 베이스에 적용하는 제4단계로 구성된 것을 특징으로 하는 전전자 교환기의 DBMS의 데이타 베이스 백업 및 회복하는 방법.A method for backing up and restoring a database in a database management system (DBMS) of an electronic switchgear, the first step of receiving a backup data change request from an application program, making a change log, and storing the change in a log file. After the first stage backup request (backup request from the operator, backup request when the log file size threshold is exceeded, and backup request when the server is busy), the contents of the load file required for backup are stored in the corresponding database on disk. A second step of backing up to the second step; receiving a recovery request from the downed processor after the second step; requesting information on the log file; and loading the log file after the third step into a database in the memory. A method of backing up and restoring a database of a DBMS of an electronic switchgear, comprising a fourth step of applying. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
