Oracle Database Administration from Zero to Hero - Performing Recovery Part II - Switching Data Files and Performing PIT

This video tutorial covers the process of performing database recovery using RMAN, focusing on switching data files and point-in-time recovery (PITR). It explains how to recover data files by switching to image copies, the benefits of this method, and scenarios where it can be applied. The tutorial also provides recommendations for storing data file copies and considerations for performance. Key RMAN commands such as SWITCH DATA FILE and RECOVER are discussed, along with practical scenarios for complete and partial data file recovery.

What is the primary focus of the RMAN recovery lecture?

• Switching data files and point-in-time recovery

• Network configuration

• User management

• Database tuning

What is the main advantage of switching data files using RMAN?

• It creates new data files from scratch

• It updates the database to point to existing data file copies

• It requires shutting down the database

• It is slower than restoring from backup sets

Where is it recommended to store data file copies?

• On the same disk as the production data files

• As part of the FRA

• In a different location than the FRA

• On a network drive

What should be considered if data file copies are stored separately from production data files?

• They should have similar specifications to the production storage

• They should be on a slower disk

• They should be encrypted

• They should be on a different network

What is the first step in recovering all lost database data files?

• Take the database offline

• Mount the database

• Create new data files

• Open the database for read-write operations

In a scenario where a user tablespace data file is lost, what is the initial action?

• Switch the database

• Create a new data file

• Take the data file offline

• Shut down the database

What is the final step after applying changes to data file copies in a recovery scenario?

• Delete the old data files

• Bring the data file back online

• Shut down the database

• Create a backup
