 - `-b <pdb1,pdb2>`   Comma-separated list of PDBs to clone (include only these PDBs. `PDB$SEED` is always included)
 - `-c <channels>`    Number of RMAN channels to use (sets `numChannels` in the API payload)
 - `-d`               Dry run mode - show API payload without executing
+- `--refresh`        Refresh target database before cloning (if it exists)
+
+### Refresh Functionality
+
+The `--refresh` flag provides an automated way to refresh the target database before cloning:
+
+- If a database with the target name already exists on the target host, it will be refreshed first
+- The script monitors the database status and waits for it to enter 'relic' state
+- Once the database is in relic state, the cloning process proceeds normally
+- The refresh operation has a 2-minute timeout to prevent indefinite waiting
+- Use Ctrl+C to cleanly abort the refresh process at any time
+
+**Example with refresh:**
+```bash
+./oracle_clone.sh -s prod-db01 -d PRODDB -t test-db01 -n TESTDB --refresh
+```

 - `RUBRIK_IP`: The IP address or DNS name of your Rubrik CDM cluster.
 - `ID`: The service account ID or user credential for API authentication.
 - `SECRET`: The secret or password for the service account/user.
