E. ASM 라이브러리 및 DB Engine 설치.

Oracle Enterprise Linux 4 버전에는
ocfs2 나 oracleasm 이 전부들어있어서 설치하기는 편하다.

본인들이 다른OS에서 설치할때는 오라클사이트에서 직접 커널버전에 맞는 RPM을 찾아서 설치를
해야한다.

1. ASM 라이브러리 설치 (두노드에서)

3. oracleasm configure(두노드에서)
[root@ocm1 /]# /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
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver:                     [  OK  ]
Scanning the system for Oracle ASMLib disks:               [  OK  ]

4. oracleasm 디스크그룹 생성(둘중 한노드에서)
[root@ocm1 /]# /etc/init.d/oracleasm createdisk data1 /dev/sdc1
Marking disk "data1" as an ASM disk:                       [  OK  ]
[root@ocm1 /]# /etc/init.d/oracleasm createdisk data2 /dev/sdd1
Marking disk "data2" as an ASM disk:                       [  OK  ]
[root@ocm1 /]# /etc/init.d/oracleasm createdisk flash1 /dev/sde1
Marking disk "flash1" as an ASM disk:                      [  OK  ]
[root@ocm1 /]# /etc/init.d/oracleasm createdisk flash2 /dev/sdf1
Marking disk "flash2" as an ASM disk:                      [  OK  ]
[root@ocm1 /]#

data1 , data2 는 오라클데이터로
flash1 , flash2 는 플래시 백 복구영역으로 사용할예정이다.

[root@ocm1 rpm]# /etc/init.d/oracleasm listdisks
DATA1
DATA2
FLASH1
FLASH2
[root@ocm1 rpm]#
ASM으로 인식하는 리스트들을 확인하고 나머지 다른노드에서도 확인해본다.
