Oracle Database Administration from Zero to Hero - Automating Tasks with the Scheduler

This lecture covers Oracle Scheduler, a tool for managing database jobs. It explains key features like job scheduling, resource management, and event-based scheduling. The lecture details how to create and manage scheduler jobs using the DBMS_SCHEDULER package, including setting job parameters and repeat intervals. Advanced scheduling options and examples are provided. The lecture also discusses managing scheduler components like programs and schedules, and introduces additional components such as job classes and windows.
