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 license agreement which
accompanied, or was contained in, the Program for which you are obtaining
the PTF.  You are not authorized to install or use the PTF except as part
of a Program for which you have a valid Proof of Entitlement.

APAR Error Description / Circumvention

-----------------------------------------------
During normal termination of an application with multiple
threads running constructors to initialize static storage, it is
possible for the ILE runtime to get into a loop trying to call
the associated destructors. The looping job can be terminated
only with the ENDJOBABN (end job abnormal) command.

CORRECTION FOR APAR SE66175 :
-----------------------------
A scenario was found for which the ILE runtime was not
completely thread safe and a loop occurred. The ILE runtime has
been updated to prevent it from looping.

CIRCUMVENTION FOR APAR SE66175 :
--------------------------------
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THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED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SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI50476 :
=================================================

This PTF can, under rare circumstances, cause other PTFs installed at
the same time to be marked as damaged.  It is also possible for this
PTF to cause CEE9902 messages to be issued in other jobs that are
running at the time that this PTF is installed.  To avoid the first
problem it is recommended that this PTF be installed in a separate job.
Sign off the system and then sign back on before applying additional
PTFs.  To minimize the chances of the CEE9902 messages in other jobs
make sure that there are a minimal number of jobs running on the system
at the time that the PTF is applied.  Another option would be to apply
the PTF immediately prior to a scheduled IPL of the system.

If a PTF is marked as damaged as the result of being applied in the
same job as this PTF you can use RMVPTF with the RMV(*PERM) option to
remove the damaged PTF, then use LODPTF and APYPTF in a new job to
apply the PTF that was marked as damaged.  The APYPTF in the new job
should be successful.  If it is not then the PTF that was marked as
damaged was damaged for some reason unrelated to this PTF.

If you see CEE9902 exception messages in other jobs after installing
this PTF then ending the affected jobs and starting them again will
avoid the CEE9902 exception messages.  If the CEE9902 exception
messages persist after restarting the job then the messages are
unrelated to this PTF.


Default Instructions

THIS IS A DELAYED PTF TO BE APPLIED AT IPL TIME.
