오라클 ASM 에서 filesystem으로 복사 하는 3가지 방법

1) Using ASMCMD Utility ( Latest method )
2) Using RMAN ( alternative method )
3) Using DBMS package ( old method )

=============================================================

 

 ASM 에서 filesystem으로 복사 하는 3가지 방법이 있습니다.

위 3가지 방법 중에서는 1,2번(asmcmd cp,rman copy) 방법이 제일 간단히 할 수 있겠습니다.

감사합니다.
