After a very, very long wait, finally onpremisses has been released.
As a starting point, we are on a Oracle Linux 8.10 (x86_64) server on kernel 5.15.0-316.196*, with at least 16G of swap.
[root@ol826ai ~]# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.9 (Ootpa)
[root@ol826ai ~]# uname -a
Linux ol826ai 5.15.0-205.149.5.1.el8uek.x86_64 #2 SMP Fri Apr 5 12:44:45 PDT 2024 x86_64 x86_64 x86_64 GNU/Linux
[root@ol826ai ~]#Lets install few bits and reboot:
[root@olinux8 ~]# yum install policycoreutils-python-utils
[root@olinux8 ~]# dnf install perl
[root@olinux8 ~]# yum install chkconfig
[root@olinux8 ~]# dnf -y install oracle-ai-database-preinstall-26ai
[root@olinux8 ~]# yum update -y
[root@olinux8 ~]# reboot
[root@olinux8 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.10 (Ootpa)
[root@olinux8 ~]# uname -a

[root@olinux8 ~]#Make sure oinstall has assigned oracle in /etc/group file. This might not give you any issues on this example, but on a system with role separation (GRID and RDBMS having different users) can cause trouble… :
[root@olinux8 ~]# groups oracle
oracle : oinstall dba oper backupdba dgdba kmdba racdba
[root@olinux8 ~]# grep -i oinstall /etc/group
oinstall:x:54321:oracle
[root@olinux8 ~]#Add oracle groups:
[root@olinux8 ~]# groups oracle
oracle : oinstall dba oper backupdba dgdba kmdba racdba
[root@olinux8 ~]# groupadd -g 54327 asmdba
[root@olinux8 ~]# groupadd -g 54328 asmoper
[root@olinux8 ~]# groupadd -g 54329 asmadmin
[root@olinux8 ~]# usermod -g oinstall oracle
usermod: no changes
[root@olinux8 ~]# usermod -G wheel,dba,oper,backupdba,dgdba,kmdba,racdba,asmdba,asmoper,asmadmin oracle
[root@olinux8 ~]# groups oracle
oracle : oinstall wheel dba oper backupdba dgdba kmdba racdba asmdba asmoper asmadmin
[root@olinux8 ~]#
** make sure this is still ok:
[root@olinux8 ~]# grep -i oinstall /etc/group
oinstall:x:54321:oracle
[root@olinux8 ~]#
Lets format the disks we want to use:
[root@olinux8 ~]# lsblk --list | egrep "sda|sdc"
sda 8:0 0 100G 0 disk. <-- DATA
sdc 8:32 0 50G 0 disk <-- FRA
[root@olinux8 ~]# ls -tlr /dev/sd[a,c]

[root@olinux8 ~]#

[WARNING] [INS-41813] OSDBA for ASM, OSOPER for ASM, and OSASM are the same OS group.
CAUSE: The group you selected for granting the OSDBA for ASM group for database access, and the OSOPER for ASM group for startup and shutdown of Oracle ASM, is the same group as the OSASM group, whose members have SYSASM privileges on Oracle ASM.
ACTION: Choose different groups as the OSASM, OSDBA for ASM, and OSOPER for ASM groups.
[WARNING] [INS-41875] Oracle ASM Administrator (OSASM) Group specified is same as the users primary group.
CAUSE: Operating system group oinstall specified for OSASM Group is same as the users primary group.
ACTION: It is not recommended to have OSASM group same as primary group of user as it becomes the inventory group. Select any of the group other than the primary group to avoid misconfiguration.
