Produktbeschreibung

This course takes the database administrator beyond the basic tasks covered in the first workshop. You'll begin by gaining a much deeper understanding of possibly the most important job of a DBA: backup and recovery.

Learn To:

  • Automate DBA tasks with the Scheduler.
  • Diagnose and repair data failures with Flashback technology.
  • Manage space to optimize database storage and to be able to respond to growing space requirements.
  • Monitor and manage major database components, including as memory, performance and resources.
  • Secure the availability of your database by appropriate backup and recovery strategies.

Backup & Recovery

Expert instructors will also help you explore the concepts and architecture that support backup and recovery. You'll become familiar with the steps of how to carry it out in various ways and situations. Gain the skills to define and test your own backup and recovery scenarios.

Learn Performance Evaluation & Tuning Tasks

This course will also teach DBAs how to manage memory effectively. Learn how to perform some performance evaluation and tuning tasks, including using some of the advisors.

You'll also learn about the different types of flashback technologies, scheduling jobs inside and outside of the database and controlling system resource usage.
