Backup database:

  1. Connect to Oracle database using RMAN (Recovery Manager) tool.
  2. Execute the RMAN backup command to back up the database, for example: “backup database plus archivelog”.
  3. Once the backup is complete, you can copy the backup files to another location or storage medium to prevent data loss.

Restore the database.

  1. Connect to the Oracle database using the RMAN tool.
  2. Execute the RMAN restore command, such as: restore database.
  3. During the restoration process, additional commands from RMAN may be needed to address the database’s extra requirements, such as reconstructing the control file or recovering archived logs.
  4. After the restoration is complete, you can open the database for normal operations.

It is important to have the necessary permissions and knowledge of RMAN tool usage and parameters before starting the backup and restore process. Additionally, to minimize data loss, it is recommended to regularly backup the database and store the backup files in a secure location.
