Oracle ASM 설정 및 시작

# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
 
This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.
 
Default user to own the driver interface []: oracle
Default group to own the driver interface []: oinstall
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y

디스크 생성

asmca create slient 스크립트 및 실행

(ORADATA라는 디스크그룹에 ASM01, ASM02를 넣어 생성)

$ cat asmca_create.sh 
asmca -silent -createDiskGroup \
  -diskGroupName ORADATA \
  -diskList 'ORCL:ASM01,ORCL:ASM02' \
  -redundancy Nomal \
  -au_size 4 -compatible.asm 11.2 \
  -compatible.rdbms 11.2 \
  -sysAsmPassword oracle
  
$ sh asmca_create.sh 
 
Disk Group ORADATA created successfully.

디스크 추가

asmca add slient 스크립트 및 실행

(ORADATA라는 디스크그룹에 FRA01이라는 디스크를추가)

$ cat asmca_add.sh 
asmca -silent -addDisk \
  -diskGroupName ORADATA \
  -diskList 'ORCL:FRA01' \
  -redundancy Normal \
  -au_size 4 -compatible.asm 11.2 \
  -compatible.rdbms 11.2 \
  -sysAsmPassword oracle
  
$ sh asmca_add.sh 
 
Disks added successfully to disk group ORADATA

디스크 삭제

개별 디스크 삭제옵션(deleteDisk)은 제공하지 않고 모든 ASM 인스턴스를 삭제하는 기능(deleteASM)만 제공한다.

Delete Oracle ASM Instances

-deleteASM deletes all the Oracle ASM instances that are present. 

The operation stops and an error is raised if there is a database using the Oracle ASM instance.

해석

-deleteASM 명령어 : 존재하는 모든 Oracle ASM 인스턴스를 삭제합니다. 

작업이 중지되고 Oracle ASM 인스턴스를 사용하는 데이터베이스가 있으면 오류가 발생합니다.
