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

-----------------------------------------------
When performing cluster commands, a low level task may encounter
an unexpected exception which may cause clustering to hang.

Symptoms seen are the ability to not be able to start
clustering, as well as when ending cluster CRGs or cluster
nodes, the cluster command may just hang. If trying to manually
end the cluster controller job QCSTCTL, it will not end.

CORRECTION FOR APAR MA44503 :
-----------------------------
The error causing the exception will be corrected.

CIRCUMVENTION FOR APAR MA44503 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


In order to fix the problems described by this PTF, the PTF must be
applied on all nodes (on the same release as this PTF) in the cluster.
However, the entire cluster does not have to be ended to do this.  One
node at a time can be ended, the PTF applied, and the node restarted to
join the cluster.

Note, you must end Cluster Resource Services on the node, apply the
PTF, and then restart Cluster Resource Services before the fix is
available.

To determine if Cluster Resource Services is active on your system, do
a WRKACTJOB from the command line of your system and look for two
system jobs (QCSTCTL and QCSTCRGM).  If either of these jobs exist,
Cluster Resource Services must be ended on this system and you must
sign off all sessions where Cluster Resource Services APIs were used
before the PTF can be applied.  Cluster Resource Services is started
through the Start Cluster Node API.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
