The connector constructs a mining range based on a start/end system change number. LogMiner will use this range to create a non-inclusive range by going 1 SCN beyond the given range. If this range exceeds the SCN details available in the supplied logs, LogMiner will then fail with this error.

The solution is to always make sure the upperbound is less-than LAST_REDO_SCN or less-than or equal-to LAST_REDO_SCN-1, a column found in V$THREAD.
