1. ASM 구성

A) ASM 인스턴스 및 디스크 그룹 생성

ASM 인스턴스 및 디스크 그룹 생성

ASM 영역으로 이관된 파라미터 파일을 적용하기 위해 데이터베이스를 재기동해야 합니다.

우선은 다른 파일들도 이관을 해야 하므로 1번 노드의 데이터베이스만 기동합니다.

E) 컨트롤 파일 ASM으로 이관

콘트롤 파일 위치 변경 및 No Mount 모드로 기동
alter system set control_files='+DATA','+FRA' sid='*' scope=spfile;
startup force nomount;
SQL> alter system set control_files='+DATA','+FRA' sid='*' scope=spfile;

System altered.
