Oracle Database Administration from Zero to Hero - Using RMAN Recovery Catalog (Part 3 of 3)

The video tutorial explains the use of stored scripts in RMAN for automating tasks. It covers the types of stored scripts, how to create and manage them, and the differences between local and global scripts. The tutorial also discusses executing and updating scripts, using substitution variables, and maintaining stored scripts. Finally, it provides guidelines for backing up the recovery catalog database, emphasizing the importance of using RMAN and keeping backups separate from production data.

What is a key advantage of stored scripts over command files?

• They are faster to execute.

• They require less storage space.

• They are easier to write.

• They can be accessed by any RMAN client connected to the target database.

What distinguishes a global stored script from a local one?

• Global scripts require more storage space.

• Global scripts are faster to execute.

• Global scripts can be executed on any database registered in the recovery catalog.

• Global scripts are easier to write.

Which keyword is used to create a global stored script?

• Shared

• Universal

• Common

• Global

What command is used to update an existing stored script?

• Change script

• Replace script

• Update script

• Modify script

How can substitution variables be included in a script?

• Using the $ symbol followed by a number

• Using the & symbol followed by a number

• Using the # symbol followed by a number

• Using the % symbol followed by a number

Which command is used to display the code of a specific stored script?

• Display script

• Show script

• Print script

• View script

What happens if the global keyword is not used in a command?

• The command will return an error.

• The command will not execute.

• The command will only affect local scripts.

• The command may affect a global script if no local script is found.

Why is it important to back up the Recovery Catalog database?

• It keeps a record of all the backups of your databases.

• It is used to store production data.

• It contains all the scripts used by RMAN.

• It is larger than the production database.

What should be avoided when storing data in the Recovery Catalog database?

• Storing configuration files

• Storing production data

• Storing RMAN scripts

• Storing backup logs

What is recommended to ensure the safety of the Recovery Catalog database?

• Store it on the same disk as the target database.

• Do not back it up frequently.

• Back it up after each target database backup.

• Use it to store production data.
