This is a demo install of Oracle Database Server 21c and 23c on Oracle Linux 8.
Environment
VirtualBox or any other virtual machine manager.
Operating system
Use Oracle Linux 8.9 for Oracle Database 23c and Oracle Linux 9.4 for Oracle Database 23ai.
Oracle Linux 8.9
OracleLinux-R8-U9-x86_64-dvd.iso
Oracle Linux 9.4
Install
Virtualbox
2 CPU, 2GB RAM, 40GB HDD FIXED SIZE, 64MB VMSVGA
Take note of MAC address and configure DHCP server with a fixed address.
Install Oracle Linux 8.X
During install do not use scaled mode because it can cause problems with the GUI. CTRL+C will exit scaled mode if enabled (CTRL+ALT will return you to the desktop).
Setup as follows:
- Select language: English (United Kingdom)
- Time & Date: Etc → Coordinated Universal Time
- Software Selection: Server → Headless management, system tools
- Installation Destination: X, automatic partitioning
- Network and Host: ON → hostname.kewl.org
- Root Password
Begin installation… Reboot System
KVM
virt-install
--location OracleLinux-R8-U9-x86_64-dvd.iso,kernel=isolinux/vmlinuz,initrd=isolinux/initrd.img
Login
$ ssh root@hostname.kewl.org
Update
$ yum update Y $ reboot
Firewall
Disable the firewall is network connections to the database are required.
systemctl stop firewalld systemctl disable firewalld systemctl mask firewalld
Virtualbox Additions
Virtualbox needs the VBox Linux Additions so we can mount a share on the VM. This is to access downloaded files on the host machine with a shared folder.
Install kernel and tools
$ yum install kernel-uek kernel-uek-devel make perl Y $ reboot
Install module
$ uname -a Linux hostname.kewl.org 5.4.17-2136.307.3.1.el8uek.x86_64 #2 SMP Mon May 9 17:29:47 PDT 2022 x86_64 x86_64 x86_64 GNU/Linux $ mount /dev/sr0 /mnt $ /mnt/VBoxLinuxAdditions.run
Oracle DB Server 21c
The install guide is mostly for the ZIP version but we shall install the RPM for OL8.
Preinstall
The O/S needs to be setup for Oracle, a preinstall RPM does this automatically for us.
$ yum install ./oracle-database-preinstall-21c-1.0-1.el8.x86_64.rpm Y $ reboot
Install
Now we can install the Database Server and afterward configure it with the example database.

23c or 23ai
First remove the database example using script or dbca tool (if installed).
Login as root
23c
/etc/init.d/oracle-free-23c delete
23ai
/etc/init.d/oracle-free-23ai delete
Login as oracle
With dbca create a database named FREE.
In this example a database with 16 PDBs with the PREFIX DB is created using the “Advanced configuration”.
