You can echo the username and password and pipe it into either sqlplus or sqlldr.

Code:
echo "${USERNAME}/${PASSWORD}@${TNS_ALIAS}" | sqlplus ...
echo "${USERNAME}/${PASSWORD}@${TNS_ALIAS}" | sqlldr ...

You can also create a password file under your $HOME/.ssh directory and have a separate script read that file and store the passwords as local environment variables. Meaning to add the word export. If someone can log on as the Oracle user on a Linux/Unix system they can authenticate using the us user.

Code:
sqlplus '/as sysdba'

Thus you already need to keep the $HOME/.ssh locked down, so that is the best place to keep passwords.

NAME

       systemd-ask-password-console.service, systemd-ask-password-console.path, systemd-ask-password-wall.service, systemd-ask-password-wall.path
       - Query the user for system passwords on the console and via wall

       systemd-ask-password-wall.service

       systemd-ask-password-wall.path

DESCRIPTION

       systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and
       SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for
       boot.  systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is
       intended to be used after boot to ensure that users are properly notified.

       See the developer documentation[1] for more information about the system password logic.

       Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line
       parameters.
