Alas that’s a common complaint – for every version that’s had it.

As it says in “philosophy 1″ histograms and bind variables don’t go together – and cursor_sharing != exact combined with method_opt => “auto” gives you the worst possible combination of the pair.

Our workaround is: flush a single sql (http://kerryosborne.oracle-guy.com/2008/12/flush-a-single-sql-statement-take-2/).

Btw, i guess this problem is related as well to Oracle (default Job) collect histogram in for example: pk columns.

Thanks for the input.
