NOTICE:

Application of this PTF may disable or render ineffective programs that
use system memory addresses not generated by the IBM translator,
including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the 'IBM License Agreement for Machine
Code', the terms of which were provided in a printed document that was

APAR Error Description / Circumvention

-----------------------------------------------
When a new table is created, database attempts to determine the
average read response time associated with it for use during
query optimization.  Part of this process can result in
temporary storage segments being created, extended and
truncated.  If tables are created and deleted rapidly, this
overhead can be significant.

CORRECTION FOR APAR MA47317 :
-----------------------------
Changes were made to use the average read response time of the
ASP that very small or empty tables reside on, reducing system
overhead.

CIRCUMVENTION FOR APAR MA47317 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF65166 :
=================================================

This PTF may not resolve issues with indexes or maintained temporary
indexes (MTI) that existed prior to application.  An IPL is required to
ensure complete resolution.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
