Protection Group snapshots provide write-order consistency across their member volumes. The Oracle recovery action after restore depends on how the snapshot was created and on the recovery objective.
| Source snapshot type | Typical recovery behavior | Operational guidance |
|---|---|---|
| Application-consistent | Oracle may require media recovery using required archived redo; the exact action depends on whether hot backup mode or suspend was used and what redo is available. | Follow the documented recovery plan and retain all archived redo that covers the snapshot point. Do not assume that ALTER DATABASE OPEN alone is always sufficient. |
| Crash-consistent | Oracle performs instance/crash recovery when the database starts; further recovery may be needed depending on restored files and the desired recovery point. | Expect recovery and validate the alert log. Do not use RESETLOGS unless the recovery path requires it. |
