Oracle 10g RAC On Linux Using VMware Server
http://www.oracle-base.com/articles/10g/OracleDB10gR2RACInstallationOnCentos4UsingVMware.php
전체 설치를 했으면 기본적으로 추가 설치는 필요가 없습니다.
설치가 필요한 경우는 -q 옵션 명령으로 확인하고 없으면 -Uvh 옵션으로 설치합니다.
CD에 iso가 그대로 있다면 /media/RHEL_5.3 i386 DVD/Server 에 가면 RedHat5에서 제공하는 rpm 들이 있습니다.
확인 : rpm -q 패키지명
설치 : rpm -Uvh 패키지명
필요한 패키지들은 다음과 같습니다.
rpm -q gcc glibc-devel glibc-headers glibc-kernheaders cpp compat-libstdc++ openmotif
glibc-kernheaders 와 compat-libstdc++ 가 설치안되었다고 나오는데 일단 넘어갑니다.

호스트 윈도우에서 D:\VMware\rac\shared 에 생성한 두 개의 disk를 fdisk로 분할합니다.
root 계정으로 작업합니다.
raw 시스템으로 생성하며,
Clusterware에서 사용하는 voting (200MB), OCR (200MB) 을 만들고,
control (200MB X 4), redo (300MB X 6), data (2GB X 5) 를 만들겁니다.
각각 만들어진 파티션에는 하나의 tablespace만이 들어갈 수 있습니다.
반드시 나중을 위해서 어떤 파이션에 어떤 tablespace가 있는지 엑셀로 따로 정리를 해 두어야 합니다.
# cd /dev
# ls sd*
sda sda1 sda2 sdb sdc
sdb, sdc가 두개의 Shared Disk 입니다.
fdisk로 분할합니다. sdb는 13개로 분할하고, sdc는 5개로 분할합니다. (disk당 최대 15개까지 가능)
[root@rac1 dev]# fdisk /dev/sdb
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n

Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
n : 새로 파티션을 만듭니다.
1 : 1번 파티션
+200M : 200MB로 생성
p 또는 e : primary 또는 extended
w : 저장
전부 4개의 파티션을 만들 수 있는데 extended를 사용하려면
마지막 4번째의 파티션을 extended로 전체 할당하고, 4번째 파티션을 다시 10개로 나눕니다. (최대 12개까지 가능)
이렇게 sdb를 13개의 파티션으로 나눕니다. ( P 200M, P 200M, P 200M, E 나머지전체 ( 200M, 200M, 200M, 300M, 300M, 300M, 300M, 300M, 300M, 나머지전체 ) )
sdc는 5개로 나눕니다. (2G, 2G, 2G, 2G, 2G)
종료전에 w로 저장을 꼭 해야합니다.

공유 Disk 설정
RAC1을 shutdown하고 RH5Rac1폴더에 Red Hat Linux.vmx 에 다음을 추가합니다.
disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"

RAC2를 만들기 위해서 리눅스를 다시 설치할 필요가 없습니다.
복사만 해주면 되는데 그 전에 해야할 것이 있습니다.
- RAC1 리눅스를 shutdown하고 RH5Rac2 폴더를 만들고 안에 있는 모든 파일을 복사합니다.
- Red Hat Linux.vmx 파일에 displayName만 변경하면 됩니다.
displayName = "RH5Rac2"
- RAC1과 RAC2를 모두 시작합니다.
eth0.bak과 eth1.bak은 삭제합니다.
eth0은 192.168.89.102
eth1은 192.168.206.102로 셋팅합니다. 셋팅후, 비활성화, 활성화를 하여 반영합니다.
DNS 탭에서 호스트명을 rac2로 변경합니다.
저장하고 종료합니다.
rac1과 rac2에서 서로 ping이 되는지 확인합니다.
hostname 변경 적용을 위한 rebooting
clusterware 설치시 서버 통신하기 위해서 셋팅이 필요합니다.
