1.2 Création des utilisateurs
Sur Oracle Linux 6.5, l’utilisateur oracle est créé lors de l’installation.
Créer l’utilisateur grid :
[root@oracledb ~]# id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),54322(dba)
[root@oracledb ~]# useradd -g oinstall -G asmadmin,asmdba,asmoper grid
Ajouter l’utilisateur oracle dans le groupe asmdba :
[root@oracledb ~]# usermod -aG asmdba oracle

[root@oracledb ~]# mkdir -p /vol/01/app/oracle/product/12.1.0/oraclehome
[root@oracledb ~]# mkdir -p /vol/01/app/grid/product/12.1.0/gridhome
[root@oracledb ~]# chown -R grid.oinstall /vol/01/app/grid
[root@oracledb ~]# chown -R grid.oinstall /vol/01/app/oraInventory
[root@oracledb ~]# chown -R oracle.oinstall /vol/01/app/grid
[root@oracledb ~]# chmod -R 775 /vol/01/app

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
