Overview/Description
Oracle Database 12c allows for the duplication of a database. This can be useful for numerous reasons, including for implementing a testing environment or for doing recovery operations. To duplicate a database there are various steps you need to complete to first prepare the environment when the database will be duplicated to and then the RMAN DUPLICATE command can be used. As with any tool or feature that using resources RMAN can have performance issues. These issues need to be identified and then corrected based on performance issues that was detected. Oracle Database 12c provides tools and features to do this task. This course will discuss and show how to duplicate a database as well as how to troubleshoot and tune RMAN. This course is one of a series in the Skillsoft learning path that helps prepare the learner for the Backup and Recovery portion of the Oracle exam 1Z0-063, Oracle Database 12c: Advanced Administration.

Target Audience
Database administrators, support engineers, technical administrators, and data warehouse administrators who wish to develop appropriate strategies for backup, restore, and recovery procedures

Prerequisites
