1. Standby DB Instance 기동
A) nomount 모드로 DB 시작

2. RMAN을 이용한 DB 복제
A) RMAN 접속
RMAN 으로 Primary와 Standby 동시 접속
rman TARGET sys/[sys 계정 암호]@[primary 네트워크 서비스명] AUXILIARY sys/[sys 계정 암호]@[standby 네트워크 서비스명]

B) Duplicate 명령으로 DB 복제
운영 중인 DB를 RMAN으로 standby 서버에 복제
DUPLICATE TARGET DATABASE
FOR STANDBY
FROM ACTIVE DATABASE -- 운영 primary로부터 복제
-- BACKUP LOCATION '[백업 저장 경로 (디스크)]' -- 백업으로부터 복제 (디스크 저장)
-- FROM FILE '[백업 메타 정보 XML 파일]' -- 백업으로부터 복제 (테이프 장치)

SET cluster_database='FALSE'
SET db_unique_name='[standby 글로벌 DB명]' COMMENT 'Is standby'
SET FAL_SERVER='[primary 글로벌 DB명]' COMMENT 'Is primary'
