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

REGARDING THE PTF.
APAR Error Description / Circumvention
-----------------------------------------------
Integrated Language Environment (ILE) modules, programs, and
service programs created with optimization levels 30 (*FULL) or
40 may compute incorrect pointer addresses. Symptoms may
include exceptions (MCH0601, MCH3402, MCH3601), null pointers,
or unpredictable behavior caused by addressing an incorrect
memory location.
CORRECTION FOR APAR MA43862 :
-----------------------------
Licensed Internal Code for the optimizing translator has been
changed to generate correct pointer addresses. Affected
modules, programs, and service programs must be re-created.
CIRCUMVENTION FOR APAR MA43862 :
--------------------------------
Change the module, program, or service program to use a low
optimization level (10 or 20). For example:
CHGPGM ... OPTIMIZE(20)
Activation Instructions
None.
Special Instructions
If you have not experienced this problem, nothing needs to
be done. If you have experienced this problem, you need to
do the following to re-create each affected program:
Use the DSPPGM or DSPSRVPGM command to see whether observable
information exists.
If the program has all observable information, then use the
CHGPGM or CHGSRVPGM command with keyword FRCCRT(*YES) to force
program re-creation.
If creation data has been made unobservable, you can
re-create the programs using other methods. One way is to
restore the programs, either after setting the QFRCCVNRST
system value to 7 or by specifying the FRCOBJCVN(*YES *ALL)
parameter on the restore command (RST, RSTOBJ or RSTLIB).
Another way to re-create programs without observable
creation data is to recompile the program source code, using
your choice of optimization level.
Default Instructions
THIS IS A DELAYED PTF TO BE APPLIED AT IPL TIME.
