What must a user be granted to run the CREATE_DATABASE_LINK as a user other than ADMIN?

To run the CREATE DATABASE LINK command as a user other than ADMIN, it is essential to have the EXECUTE privilege on the CREATE DATABASE LINK command. This specific privilege allows users to create database links, which are essential for establishing a connection with other databases.

Having the EXECUTE privilege provides the necessary permissions to invoke specific procedures or commands in Oracle databases without granting broader or unnecessary access rights, thus maintaining security and control within the database environment. This targeted permission model is fundamental in database management, allowing for the principle of least privilege to be adhered to.

Other options, such as having the ADMIN role or needing FULL DATABASE access, could grant excessive privileges that are often not necessary for the task of creating a database link. Similarly, the CREATE TABLESPACE privilege is unrelated to the action of creating database links, as it pertains to the creation of tablespaces, not database connectivity. Therefore, the specific requirement of having the EXECUTE privilege on CREATE DATABASE LINK is the most appropriate and secure choice for accomplishing the task.
