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

-----------------------------------------------
Attempting to access an opportunistically locked file through
the Network File System (NFS) server results in MSGMCH3601
(Pointer not set for location referenced.) and the job becomes
unresponsive.  The job may not end even when the End Job
Abnormal (ENDJOBABN) command is used.  An IPL is the only
recovery.

CORRECTION FOR APAR SE55515 :
-----------------------------
The opportunistic locking release processing is incorrectly
treating the NFS server job as if it is a file server job.  This
causes a failure in accessing file server data structures.  The
PTF corrects the problem.

CIRCUMVENTION FOR APAR SE55515 :
--------------------------------
None.


Activation Instructions


This PTF contains objects that are activated only at IPL time.
Therefore, if this PTF is applied as an immediate PTF, you must
perform an IPL of the system to activate the PTF. Applying the
PTF as an immediate PTF will ensure that the PTF becomes active
even after an abnormal IPL where delayed PTFs are not applied.

If the PTF is applied as a delayed PTF, no further action is
necessary.





Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
