APAR Error Description / Circumvention

-----------------------------------------------
Unexpected access path sharing occurs when two derived key SQL
indexes are created having the same keys with a zero length
string as a comparison value.

For example:
CREATE INDEX MYIDX1 .... ( fld1, fld3 ) WHERE fld1 <> '' AND
fld2 = 'a'
CREATE INDEX MYIDX2 .... ( fld1, fld3 ) WHERE fld1 <> '' AND
fld2 = 'b'

The indexes should not share and may cause incorrect results
using native i/o.

CORRECTION FOR APAR SE70023 :
-----------------------------
The CREATE INDEX code is corrected to no longer share indexes
for this case.  This ptf is preventative not corrective.

CIRCUMVENTION FOR APAR SE70023 :
--------------------------------
None.
