An administrator initiates a Point-in-Time Recovery (PITR) for a specific Oracle Pluggable Database (PDB) through...

NDB coordinates Oracle-native recovery mechanisms when restoring a selected PDB to a specified point in time. Time Machine supplies the required snapshot and transaction-log recovery points, while Oracle Recovery Manager restores the necessary PDB datafiles and applies archived redo through the requested timestamp. Oracle redo is maintained at the container database level, so the process does not literally use a completely independent redo stream for each PDB. Nevertheless, Oracle’s recovery operation limits the recovery scope to the selected PDB and processes all required archived-log switches automatically. NDB does not reconstruct Oracle transactions using Prism Central’s Cassandra data, apply flat-text backup files, or require the administrator to append database blocks manually. Nutanix documents the ability to restore selected PDBs by snapshot or timestamp in its official Oracle PDB and CDB management guidance.
