APAR Error Description / Circumvention
-----------------------------------------------
Bad selectivity estimate for a predicate over a column in which
a high percentage of the values are in a very small range, with
a small number of outliers very far away. The bad estimate
results in an inefficient plan choice.
CORRECTION FOR APAR MA45486 :
-----------------------------
The fix will be to improve the algorithm used to provide the
estimate.
CIRCUMVENTION FOR APAR MA45486 :
--------------------------------
None.
Activation Instructions
None.
