APAR Error Description / Circumvention

-----------------------------------------------
OPNQRYF intermittently performs poorly.

Applications that perform repeated and limited positioning by
key during the single open of the cursor may intermittently use
more CPU when the file is mostly resident in memory.
The query tends to perform better when the file is not resident
in memory.

CORRECTION FOR APAR MA47488 :
-----------------------------
Changes were made to improve the performance of data space
paging performed during native key positioning.

CIRCUMVENTION FOR APAR MA47488 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
