ORA-19613: datafile [string] not found in backup set
Cause: The indicated file could not be restored, because it is not in this backup set. If the file number is zero, then this refers to the control file.
Action: This message is issued when the directory from the first backup piece is read and one or more files named for restoration were not found. The restore conversation is still active, but no data has been read and you must supply the first backup piece of a backup set that contains all of the requested files.
