My experience with this error:
<quote>
Add "statistics=none" during daily backup export command (if statistics
are really not need to be exported)
OR
export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1 prior to daily_export.
(To avoid error during Export)
*********************
OTHERWISE YOU WILL GET THE FOLLOWING ERROR
EXP-00091: Exporting questionable statistic
*********************
OTHER INFO:
There are four parameter for STATISTICS parameter
ALWAYS : Always imports database optimizer statistics
regardless of whether or not they are questionable.
NONE : Does not import or recalculate the database optimizer
statistics.
SAFE : Imports database optimizer statistics back only if
they are not questionable. If they are questionable,
recalculates the optimizer statistics.
RECALCULATE : Does not import the database optimizer statistics.
Instead, recalculates them on import.
When do we get these errors,
The precalculated optimizer statistics are flagged as questionable at
export time
if:
1)There are row errors while exporting
2)The client character set or NCHAR character set does not match
the server character set or NCHAR character set
3)A QUERY clause is specified
4)Only certain partitions or subpartitions are exported.
