RMAN-06166

Error: RMAN-06166: datafile string cannot be recovered

Causa: Incremental backups or archived redo logs needed to recover the datafile cannot be found, and no recoverable full backup or datafile copy exists.

Acción: Use the LIST command to see if there is a backup set or datafile copy that can be made AVAILABLE. If not, then the datafile is unrecoverable. If a full or datafile copy exists, then a point-in-time recovery may be possible.
