The video tutorial covers the process of duplicating a database, focusing on platform compatibility, choosing the right duplication technique, and preparing the auxiliary instance. It explains the steps to set up the auxiliary database, including creating directories, setting parameters, and configuring password files. The tutorial also discusses the importance of registering the auxiliary instance in the listener and ensuring backup files are accessible if using a backup-based technique.

What should you do if the source and destination hosts have different platforms?

• Access the auxiliary database instance through Oracle Netservice.

• Run the script UTL IRP dot SQL.

• Proceed with database duplication immediately.

• Use the Cruise platform transportation procedures.

Which duplication technique is recommended if there is a fast connection between the target and destination hosts?

• Image copy duplication

• Active database duplication

• Manual duplication

• Backup-based duplication

What files need to be decided upon for their location on the destination host?

• Backup files and image copies

• Control files, data files, and redo log files

• Oracle Netservice files

• Listener files and password files

What is the first step in preparing the auxiliary instance?

• Set up the TNS names dot Ora file

• Create a password file

• Start the auxiliary database in no mount mode

• Create directories or disk groups in ASM

Why is it convenient to copy the source host password file to the destination host?

• It ensures compatibility between hosts.

• It eliminates the need to enter passwords again.

• It simplifies the Oracle Netservice setup.

• It allows for faster duplication.
