In Oracle Autonomous Database, what does the term 'self-repairing' refer to?

In Oracle Autonomous Database, the term 'self-repairing' specifically refers to automated recovery from failures. This feature is designed to enhance the reliability and availability of the database by automatically detecting issues and initiating corrective actions to restore normal operations without requiring manual intervention.

This self-repairing capability allows the database to handle various types of failures, such as hardware or software malfunctions, ensuring minimal downtime and maintaining data integrity. The automation involved in this process not only reduces the need for constant monitoring by database administrators but also enables systems to recover swiftly, which is crucial for maintaining service levels in cloud environments.

The other options focus on related aspects of database management but do not encapsulate the full meaning of 'self-repairing' as effectively. Automatic backup generation pertains to data protection rather than active recovery. Preventive maintenance scheduling is aimed at avoiding issues before they happen, which is distinct from recovering from failures. User-driven repair mechanisms imply manual user intervention, contrasting sharply with the automated nature of self-repairing processes in Oracle Autonomous Database.
