Multitenant - Performing Backup and Restore on Pluggable database

Enabling a PDB Administrator to Backup and Restore its PDB

Scenario Preview :

  1. User creation and sysdba privilage and perform backup on pluggable database.
  2. Restore and Recover system datafile from pluggable database.
  3. Perform SCN based recovery on pluggable database.
PART 1:


We create user infodba and grant sysdba or sysbackup privlege to user and perform backup and recovery operations.


SQL> GRANT SYSDBA TO infodba;

Grant succeeded.

  • Backup Pluggable database PLM2
