[관리] Oracle 백업에 대하여 – 아랑
#### ORACLE BACKUP 절차 ######
1. 먼저 이전 DB_Server 의 환경을 검사한다.
# .bash_profile 의 환경설정 검사
# $ORACLE_HOME/dbs/파라메타(*.ora)파일 검사
–> init<SID>.ora 은 DB_name 과 실질적인 server 환경의
DB의 경로를 지정한다.
# $ORACLE_HOME/oradata/DB_name/*.ctl –> contralfile 검사 # $ORACLE_HOME/oradata/DB_name/*.log –> logfile 검사 # $ORACLE_HOME/oradata/DB_name/*.dbf –> databasefile 검사 # 기타 databasefile 검사
#테이블 스페이스 와 데이터 파일 정보
