Oracle Error Message
ORA-19614: archived log thread string sequence string not found in backup set
Reason for the Error
The indicated archived log file was named explicitly for restoration but is not contained in this backup set.
Solution
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.
