Per this, you must connect to CDB as target, not to PDB. Undo Mode - Shared Connect as TARGET to ... CDB root https://docs.oracle.com/en/database/oracle/oracle-database/19/multi/backing-up-and-recovering-cdbs-and-pdbs.html#GUID-B6EF3A32-18B6-4CDC-B668-4C7B5084F371

But the document is for PITR recovery, not complete, right? As for Restore, I don't think undo is used for restore operation, so undo being shared has nothing to do with DB behavior.

Hi, I share your thinking, but they all said BEF. Any difference for recovering just a data file?

BEF. Restoration AND recovery can be done by CDB$ROOT. Recovery can be done by CDB$ROOT or the PDB in question.
