You can configure one of the following authentication modes to connect to Oracle databases:
Oracle Database Authentication: Uses your Oracle user name and password to connect to Oracle.
Kerberos:
Uses Kerberos authentication to connect to Oracle.
When you choose this option on Windows, ensure that the user account that starts the Secure Agent service is available in the Oracle database. You don't need to enter your credentials to access Oracle.
You can't configure Kerberos authentication when you use a Hosted Agent or serverless runtime environment.
Select the required authentication type and then configure the authentication-specific parameters.
