Automating Shutdown and Start-Up

Oracle recommends that you configure the system to automatically start Oracle Database Free when the system starts, and to automatically shut it down when the system shuts down.

To automate the start up and shutdown of the listener and database, run the following commands as root:

$ sudo -s

For Oracle Linux 8 and Oracle Linux 9:

# systemctl daemon-reload
# systemctl enable oracle-free-23ai

After you configure the listener, log in as root using sudo and run the Configuration Services Script to check the status of the database and listener.

$ sudo -s
# /etc/init.d/oracle-free-23ai status

The output of this command is similar to the following:

CopyStatus of the Oracle FREE 23ai service:

LISTENER status: RUNNING
FREE Database status: RUNNING

$ sudo -s

# systemctl start oracle-free-23ai
