Chapter 3 - Creating and Configuring an Oracle Database

To configure Oracle Database Free, you can (optionally) tweak the configuration parameters located at:

/etc/sysconfig/oracle-free-23ai.conf

But if you’re ok with the defaults, skip right to the main event:

sudo /etc/init.d/oracle-free-23ai configure

Choose a Password:

Alright, human, it’s time to set the password. And not just any password. This majestic string of characters will be used for the SYS, SYSTEM, and PDBADMIN accounts.

Basically, it’s the royal key to your entire feline empire of data. So don’t mess it up.

When the installer prompts you, resist every urge to type:

oracle
oracle01
welcome1
or heaven forbid... password

Those are the litter box of passwords. We don’t do that here.

Instead, create a password that makes even a hacker-cat think twice. Try something like:

Whisk3rDB2024$
$3cUr3C@tP@l@c3_
ILuvMyDB$4C0laws

Password Rules:

May only contain alphanumeric characters from the selected database character set
Allowed symbols: underscore (_), dollar sign ($), pound sign (#)
Make it strong, unique, and as unpredictable as a zooming cat at 3 AM

After a Few Minutes...

If you kept the default configuration, Oracle will automatically create a new SID: FREE instance.
