RMAN-06054: media recovery requesting unknown log: thread string scn string
Cause: Media recovery is requesting a log whose existence is not recorded in the recovery catalog or control file.
Action: 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.
RMAN-06053: unable to perform media recovery because of missing log
Cause: This message is accompanied with another message identifying the missing log. The log would be needed to perform the media recovery, but the log is not on disk and no backup set containing the log is available.
Action: Determine if a backup set containing the log can be made available. If so, then use the CHANGE command to make the backup set available and retry the command. If not, then a point in time recovery up to the missing log is the only alternative.
RMAN-06052: no parent backup or copy of datafile number found
Cause: An incremental backup at level 1 or higher could not find any parent backup or copy of the indicated datafile. A level 0 backup of the datafile will be taken automatically.
Action: This is an informational message only.
RMAN-06051: DELETE INPUT option not implemented yet
Cause: This option was specified in a backup specification.
Action: Remove the DELETE INPUT option.
RMAN-06050: archivelog thread number sequence number is already on disk as file string
