Oracle Database Administration from Zero to Hero - Practice - Using RMAN in Oracle Multitenant Databases (Part 2 of 2)

The video tutorial covers various recovery scenarios in ACDB and PDBS databases. It demonstrates how to restore lost data files in different contexts, including CDB system files, seed container files, and user tablespace files. The tutorial also explains how to perform Point-in-Time Recovery (PITR) to recover lost data. Each scenario is presented with step-by-step instructions using RMAN, emphasizing practical experience. The session concludes with a summary of tasks performed, including creating backups and enabling local PDB administrators to manage their PDBs.

What is the primary goal of the proposed solutions in the recovery scenarios?

• To ensure data security

• To minimize data loss

• To gain experience using different solutions

• To provide the best possible solution

In the first recovery scenario, what is the initial step after identifying the lost CDB system data file?

• Delete the data file

• Invoke RMAN and connect to the local database

• Restore the data file

• Validate the database

What is the proposed solution for recovering a lost data file in the seed container?

• Restore the entire PDB

• Create a new data file

• Restore only the lost data file

• Rewind to a previous point in time

After recovering the seed container, in which mode should it be opened?

• Read-only mode

• Maintenance mode

• Read-write mode

• Backup mode

In the third recovery scenario, what type of data file is lost?

• Seed container data file

• Redo log file

• System data file

• User tablespace data file

What is the purpose of performing a point-in-time recovery (PITR) in the fourth scenario?

• To restore the entire database

• To create a backup

• To recover a lost data file

• To recover a dropped table

What is the final step in the fourth recovery scenario after verifying the recovery?

• Enable a local PDB administrator

• Delete the testing table

• Create a new snapshot

• Switch the redo log files
