[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
