Which permission is necessary to manage a DB system in OCI?

To manage a DB system in Oracle Cloud Infrastructure (OCI), having the permission to apply patches is essential. This permission reflects administrative capabilities necessary for maintaining the database's health and security.

Applying patches is critical for ensuring that the DB system remains up to date with the latest features, security updates, and bug fixes. Database administrations often require ongoing maintenance tasks, including updates, to prevent vulnerabilities and ensure optimal performance. Without the ability to apply these patches, a user would not be able to effectively support the backend operations of the database system.

The other permissions mentioned, such as accessing the admin panel, exporting the database, and creating read-only users, are important but do not encompass the full scope of managing a DB system. Accessing the admin panel may allow for oversight of the DB system, exporting allows for data extraction, and creating read-only users assists in managing data access but doesn't address necessary updates and maintenance procedures that keep the database running efficiently. Therefore, the ability to apply patches is a foundational requirement for comprehensive database management in OCI.
