[Oracle 23c] How to install an Oracle 23c test environment on Linux 8 running on VirtualBox in five commands.

Hello all!!!

How are you doing?

Today I'll show how you can install Oracle 23c in a Linux 8 using VirtualBox.

If you need help to install Linux on VirtualBox, you can use this link: 

But always remember:
1) This step-by-step worked for me, but it may not work for you.
2) It's a basic and limited environment. The real life will be different, for sure.
3) This post is for study and testing as well, and has no concern for performance and security best practices.

So, let's get started!!!

1) We are run the dnf to install and configure pre-requirements using ROOT user.
dnf install -y oraclelinux-developer-release-el8
dnf install -y oracle-database-preinstall-23c

If you don't know what DNF is, it's a software package manager, the successor to famous YUM. The DNF check and install dependencies and determine some actions required to install this. Feel free to view this link and learn more about it: Using the DNF software package manager

2) I'll download the Oracle 23c software using WGET (or CURL).

wget https://download.oracle.com/otn-pub/otn_software/db-free/oracle-database-free-23c-1.0-1.el8.x86_64.rpm


curl -L -o oracle-database-preinstall-23c-1.0-0.5.el8.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL8/developer/x86_64/getPackage/oracle-database-preinstall-23c-1.0-0.5.el8.x86_64.rpm

3) Now, I'll install the Oracle 23c Software

dnf -y localinstall /root/oracle-database-free-23c-1.0-1.el8.x86_64.rpm

If I try to install using the Oracle user, I'll get this error:

4) It's time to create database in silent mode - using Oracle user

export DB_PASSWORD=SysOracle1106

(echo "${DB_PASSWORD}"; echo "${DB_PASSWORD}";) | /etc/init.d/oracle-free-23c configure

5) And finally, I'll enable the Oracle 23c on SYSTEMCTL

systemctl enable oracle-free-23c

The Oracle Env values are:
export ORACLE_HOME=/opt/oracle/product/23c/dbhomeFree

The credencials to connect will be:
-- CDB
sqlplus sys/SysOracle1106@//localhost:1521/free as sysdba

-- PDB
sqlplus sys/SysOracle1106@//localhost:1521/freepdb1 as sysdba

And finally, to start and stop the service, we can use:
/etc/init.d/oracle-free-23c stop
/etc/init.d/oracle-free-23c start

For this blog post, I used these great blogs:

And as Woody Woodpecker says: "That's all folks!!!"

I hope this helps you!!
