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

REGARDING THE PTF.





APAR Error Description / Circumvention

-----------------------------------------------
An access path in Delayed Maintenance logging mode becomes
"invalid" after a long duration of changes to the underlying
physical file member.   VLOG 0600-7B11 (if specific 2014 PTFs
are applied) will be generated at the time of the
invalidation/delayed maintenance log threshold being exceeded.

CORRECTION FOR APAR MA44110 :
-----------------------------
The max storage limit threshold for staying in "logging mode"
has been extended.  This is particularly beneficial to
Select/Omit access paths.

CIRCUMVENTION FOR APAR MA44110 :
--------------------------------
None.


Activation Instructions


None.
