Oracle Database Administration from Zero to Hero - Duplicating a Database Using RMAN - Part II (1 of 2)

This video tutorial covers various methods of duplicating an Oracle database using RMAN. It explains active database duplication, backup set duplication, and image copy duplication, providing detailed steps and examples for each method. The tutorial also discusses the use of compression in backup sets to reduce network traffic, highlighting the trade-offs involved. Key concepts include establishing connections, using the DUPLICATE command, and handling SP files.

Which of the following is NOT a method of database duplication mentioned in the introduction?

• Active database duplication

• Manual file copying

• Backup-based duplication with a target connection

• Backup-based duplication with a recovery catalog

What is a key requirement for active database duplication?

• Manual intervention during the process

• Multiple auxiliary databases

• A large amount of disk space

• A stable and high bandwidth network connection

When does RMAN use image copies for duplication?

• When auxiliary channels are fewer than target channels

• When the database is offline

• When the network connection is unstable

• When the USING BACKUP SET clause is specified

What is the purpose of the CONNECT AUXILIARY command?

• To connect to the target database

• To configure backup sets

• To initiate the duplication process

• To connect to the auxiliary database

How can you ensure backup sets are used without creating additional auxiliary channels?

• By using the USING BACKUP SET clause

• By increasing the number of target channels

• By disabling compression

• By using image copies

What happens to the SP file in the absence of auxiliary channels?

• Its parameters are modified on the destination

• It is copied without changes

• It is deleted

• It is ignored

What is a trade-off when using compression in backup sets?

• Increased network traffic

• Reduced CPU usage

• Increased CPU usage

• Decreased data security
