Oracle 26ai RAC 설치

미루고 있던 Oracle 26ai RAC 설치/구성을 해 보았다.

작업 과정 자체는 19c 와 크게 달라진 것은 없고 느끼는 점은 굉장히 무거워졌다.

노트북 메모리 32G인데 Virtualbox 내에서 돌리기가 굉장히 버겁다..노트북이 살려줘하는 느낌..

Multitenant 구조라 database 생성하는데 6시간 걸림..샤갈...

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

설치환경 : REHL 9.7

Oracle 23.26.1.0.0

- Directory 사전 생성

mkdir -p /u01/app/oracle

mkdir -p /u01/app/26.0.0.0/grid

mkdir -p /u01/app/oracle/product/26.0.0.0/dbhome_1

chown -R oracle:dba /u01

- Oracle Grid Infrastructure S/W설치

1. 설치파일을 FTP로 해당서버에upload

LINUX.X64_2326100_grid_home.zip <-- 설치 Image 파일

p6880880_230000_Linux-x86-64.zip <-- OPatch 파일

2. 설치이미지 압축해제 (반드시 $GI_HOME 밑에 압축해제 해야 함)

unzip LINUX.X64_2326100_grid_home.zip -d $GI_HOME

unzip p6880880_230000_Linux-x86-64.zip -d $GI_HOME

3. gridSetup.sh실행

xhost +

su – oracle

export DISPLAY=작업PC IP:0.0

cd $GI_HOME

./ gridSetup.sh 실행
