Error: RMAN-06054: media recovery requesting unknown log: thread string scn string

Causa: Media recovery is requesting a log whose existence is not recorded in the recovery catalog or control file.

Acción: If a copy of the log is available, then add it to the recovery catalog and/or control file via a CATALOG command and then retry the RECOVER command. If not, then a point in time recovery up to the missing log is the only alternative.
