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

APAR Error Description / Circumvention

-----------------------------------------------
performance improvements are being delivered within the database
query optimization and statistical components.

CORRECTION FOR APAR MA46824 :
-----------------------------
the internal SLIC DB query optimizer & stats components need
additional SLIC DB support (materialize data space attributes)
to consume in the implementation of performance enhancements.

CIRCUMVENTION FOR APAR MA46824 :
--------------------------------
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THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED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SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF61047 :
=================================================

If one or both of the PTFs for MA45275 or MA45104 have been installed
on a system when a table or physical file is saved, then BOTH of those
PTFs must also be installed on the system where the file is restored to
prevent the possibility of a restore failure.  Specifically, some files
with variable length or LOB fields may be damaged during the restore if
the PTFs are not present.  Because this may occur when restoring across
releases, PTFs for all releases are listed.

NOTE:  One or both of the PTFs for MA45275 and MA45104 may be installed
on the restore system when a table or physical file is restored even if
the PTFs were not installed on the save system at the time of the save.
This includes saving a file from a system at one release and restoring
it to a system at a different release.

The PTFs for MA45275 are:
V7R1:   MF62518
V7R2:   MF62519
V7R3:   MF61374

The PTFs for MA45104 are:
V7R1:   MF61046
V7R2:   MF61047
V7R3:   MF60986


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
