Oracle Database Administration from Zero to Hero - Practice - Creating Oracle Databases (Part 1 of 2)

This video tutorial covers the setup and configuration of Oracle databases on Linux and Windows platforms. It includes steps for setting environment variables, creating listeners, and using the Database Configuration Assistant (DBCA) in both interactive and silent modes. The tutorial also demonstrates verifying database creation, configuring EM Express for monitoring, and automating database startup on system reboot.

What is the primary reason for creating a non-CDB database in this practice?

• Non-CDB databases are more secure.

• Non-CDB databases are easier to manage.

• Many systems still use non-CDB databases.

• Non-CDB databases are faster.

What should be done if the HR schema is not created during the database setup?

• Change the in flag to A

• Change the in flag to O

• Change the in flag to E

What is the final step to ensure the database starts automatically after a reboot?

• Update the listener configuration

• Create symbolic links
