racdb_1 인스턴스가 rac1 노드에서 실행 중임
온라인 재배치: INACTIVE



One Node RAC는 클러스터 내에서 단 하나의 인스턴스만 가동되는 형태로 운영됩니다.

여러가지 이유로 가동 중인 데이터베이스를 다른 서버로 재배치할 수 있습니다.

1번 노드에서 Open된 데이터베이스를 2번 노드로 재배치하는 작업을 진행합니다.

2번 노드로 Relocate

srvctl 명령어의 relocate 옵션을 사용해서 racdb를 2번 노드로 재배치합니다.

재배치하는 과정을 상세히 보기 위해 v 옵션(verbose)을 사용하였습니다.

racdb_2 인스턴스가 정지되었습니다.
하나의 인스턴스에 대한 구성이 업데이트되었습니다.



srvctl 명령어를 사용해서 2번 노드의 데이터베이스를 다시 1번 노드로 재배치합니다.

해당 명령어는 클러스터가 동작하는 One Node RAC가 구성된 노드 어디에서든 수행할 수 있습니다.

1번 노드 Relocate 결과 확인
