DB 백업데이타로 타 서버 DB Recovery 방법(1. 아카이브 존재 시 정상복구, 2. 아카이브 유실시 비정상복구)

DR 전환 시 DB Recovery(1. 아카이브 존재 시, 2. 히든파라미터)

# DB Recovery (Archivelog 파일 존재할 시)

1. 복구 데이터를 Copy 하기에 앞서 아래 디렉토리 생성(소요시간 : 1분)

mkdir -p /orcl11/sysdata/orcl1/

mkdir -p /orcl11/ora_data/

mkdir -p /orcl12/ora_data/

mkdir -p /orcl13/ora_data/

mkdir -p /orcl14/ora_data/

mkdir -p /orcl13/bradmark/

mkdir -p /orcl14/archive

mkdir -p /export/home/orcl1/admin/orcl1/adump

mkdir -p /export/home/orcl1/admin/orcl1/bdump

mkdir -p /export/home/orcl1/admin/orcl1/cdump

mkdir -p /export/home/orcl1/admin/orcl1/udump

2. DAT TAPE에서 dbf 파일을 Restore 한 후 아래 cp 명령어 실행(Local à DBF 위치로 Copy소요시간 : 25분)
