In this course, students learn how to perform backup and recovery based on the related Oracle Database architecture components. Various backup, failure, restore, and recovery scenarios are included so that students learn to evaluate their own recovery requirements and develop an appropriate strategy for backup and recovery procedures. This course includes an interactive workshop, with scenarios that provide participants with opportunities to diagnose and recover from several database related failure situations.

Learn To:
  • Develop appropriate backup and recovery procedures to address your business needs.
  • Implement backup and recovery settings and perform backup operations to disk and tape.
  • Employ Oracle Database recovery procedures to recover from media and other failures.
  • Diagnose and repair data failures.
  • Use flashback technologies and data duplication to complement backup and recovery procedures.
  • Secure the availability of your database by appropriate backup and recovery strategies.

Benefits:
The student benefits by gaining a deeper understanding of possibly the most important job of a DBA – backup and recovery. The concepts and architecture that support backup and recovery, along with implementation steps in various ways and situations, are presented in detail.
Students gain knowledge of the Recovery Manager (RMAN) command-line interface for various backup, failure, restore, and recovery scenarios, including data duplication.
