19cRAC 2Node 기준 설치를 해 보도록 하겠습니다.
웹 사이트에 보시면 많은 분들이 설치 내용을 기입 해 주셔서 올리는것을 고민만 하다가 글을 적어 봅니다.
부족한 설명부분은 메뉴얼 , MOS, 자료실등 참고 부탁 드립니다.
중복성으로 기입 할 필요성이 없을 경우는 내용을 축소 하여 기입 한 점 미리 말씀 드립니다.
예로 ) 1Node 로그는 있으나 2Node 로그는 제외 , fdisk 설정 로그 제외
그리고 사전 Oracle VM 설정이 완료 되어야 하고, OS 설치는 할 줄 알아야 합니다.
그 외 물리적이 하드웨어 스펙인 메모리 , 디스크가 넉넉 하게 있어야 하는 점 미리 말씀 드리고 출발 합니다.
사전준비작업 -> grid 설치 -> db sw 설치 -> 패치적용 -> db 생성
또는
사전준비작업 -> grid 설치 -> db sw 설치 -> db 생성 -> 패치적용
둘중 하나의 방법으로 초기 설치를 하시면 됩니다.
필수 SW
1. 윈도우 OS 또는 리눅스 OS
2. Oracle VirtualBox - 무료
3. Oracle SW ( 리눅스버전) - 회원 가입 필요
4. Linux OS - 오라클에서 인증된 OS
6. 최신 패치 - MOS 인증 된 ID로 로그인 후 다운로드
7. VNC sw - 무료

1. 설치를 위한 사전 구성 작업
설치를 위한 초기 구성작업시 가장 중요한것은 할당되는 디스크를 공간을 어떻게 할 것인가 부터 생각을 해야 할듯 하네요.
물론 그 전에 어떤 os가 선택이 되는지가 더 중요 하겠지만, 현재 OS는 특이 사항이 아니면 X86 리눅스 버전을 설치 하도록 하겠습니다.
메뉴얼을 보고 최소 사이즈는 아래와 같이 가이드를 해 봅니다. ( 정답은 아닌점 미리 말씀 드립니다.)
엔진 설치 가이드 패치 적용까지 : 100G -> 다소 적어도 됨
OCR , VOTE DISK 분리 시 2G ~ 5G 이내
GIMR - MGMT DISK 분리 시 35G 이상
DATA Disk 분리 : 가용 가능한 공간
아카이브 파일 분리 시 : 50GB 이상 , 그 외 FRA 영역 고려 필요.

2. 사전 구성 작업 참고 자료.
메뉴얼에 나온 기반으로 잘 참고 하셔서 시스템에 맞게 잘 설정 하시면 됩니다.

3. OS 준비 작업
Os 준비작업
1. 오라클 리눅스 설치 인지 레드헷인지를 결정 하시면 됩니다.
- 오라클 리눅스는 회원가입 후 무료
- 레드헷은 이미지를 따로 구하셔야 합니다.
2. OS설치 영역
/ 영역 : 10기가
swap 영역 : 물리메모리의 1.5 이상
/boot 영역 : 500 메가
/db : db sw 25기가 공간
/dg : grid sw 35기가 공간
3. 공유디스크 준비
20기가 : 5ea
10기가 : 1ea
16기가 : 1ea
2기가 : 1ea
4. os 로컬디스크 추가분
10기가 : 2ea => 각각의 노드에 추가 예정
5. 여유분 공유디스크
8 기가 : 1ea => 공유파일시스템으로 사용 예정
1. 오라클 리눅스 설치 인지 레드헷인지를 결정 하시면 됩니다.

5. 여유분 공유디스크
8 기가 : 1ea => 공유파일시스템으로 사용 예정
4. os 세팅
1. os 세팅이 기본적으로 완료
-> RHE_LINUX.vmdk 안에 os영역을 다 넣엇습니다. RHE_LINUX2.vmdk 는 OS1세팅완료 후 복사본으로 구성 완료
2. 네트워크 설정도 완료
-> 네트워크 카드 등록은 최소 두개 이지만 저는 3개를 등록 하였습니다.
Oracle VitualBox 사용에 숙지가 필요한 부분입니다.
==> 1번, 2번 OS 디스크 할당 내용 설명
/ : os 설치영역
/db : db sw
/dg : grid sw
/LOGS : 추가분 디스크 마운트 완료 된 상태
네트웍크 IP는 아래와 같고 저희집은 SKT 통신사를 사용 중이지만 DNS 정보는 우선 제외 하겠습니다.

5. 필수 rpm 설치 확인
필수 rpm 설치하기는 반드시 자료실 및 설치 메뉴얼 참고 하셔서 잘 설치 해 주시고
설치 도중 부족한 부부은 그때 그때 설치를 하면 되지만, 너무 많으면 곤란 할듯 하니 필수 rpm은 설치를 한 후 진행 하길 바랍니다.
점검 내용
rpm -qa | grep binutils-
rpm -qa | grep compat-
rpm -qa | grep gcc-
rpm -qa | grep gcc-c
rpm -qa | grep glibc-
rpm -qa | grep libaio-
rpm -qa | grep libaio-devel-

rpm -qa | grep make-
rpm -qa | grep sysstat-
rpm -qa | grep ksh
rpm -qa | grep unixODBC
없으면 설치 해주세요.

6. OS 유저 생성
멋 스럽게 생성 해 보았습니다.
그룹을 여러개 넣었습니다. ( 사실 이렇게 까지 하실 필요 없습니다.)
색 넣은 그룹만 넣으셔도 됩니다.

groupadd -g 1011 dba
groupadd -g 1012 asmadmin
groupadd -g 1013 asmdba
groupadd -g 1014 asmoper

7. os 커널 설정
필수 커널 설정 입니다.
참고로 리눅스 6 와 리눅스7 은 좀 달라서 저는 리눅스7버전용 기반으로 설정 하였습니다.
업무적으로 os 업무를 하는 사람이 아닌지라 전문가분들이 보면 이해가 되지 않을 수 있는 점 먼저 양해 부탁 드립니다.
그리고 여기서는 hugepage 설정을 제외 합니다.
필요 시 차 후 따로 올려 보도록 하겠습니다.
## linux 7 (메모리 10기가 기준 )
vi /usr/lib/sysctl.d/00-system.conf 이곳에서 설정을 하라고 되어 있으나.
가장 확실 하게 처리 하기 위해서는..
vi /etc/sysctl.conf 파일이 가장 좋음 ( 예전 방식 )

- os 구동을 완전히 정지 후 수행 해 주세요.
- 2Node OS 복사 완료 후 간단하게 말씀 드리면 VM 메뉴에서 가상시스템 내보내기 -> 가상시스템 가지고 오기 로 진행 했습니다.
완료 후 네트워크 맥 주소 변경을 해야 하고 IP 주소도 변경 해야 합니다.
- 위의 설정이 완벽 하지 않더라도 차 후 각각의 os에서 추가 작업을 해 주어도 가능 합니다.
