including programs that circumvent control technology designed to limit

for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

APAR Error Description / Circumvention

-------------------------------------------------
Memory storage address range FFFFFFFF3E000000 thru
FFFFFFFF3EFFFFFF does not get flushed to disk during PTF
activity which may cause corruption in LIC on abnormal shutdown.
The address range FFFFFFFF3E000000 thru  FFFFFFFF3EFFFFFF may
not be used on all user systems until a later date because this
range is one of three possible address ranges that are used.   A
subset of users are affected by this problem.

CORRECTION FOR APAR 'MA45738' :
-------------------------------
The address range for FFFFFFFF3Exxxxxx is changed to
FFFFFFFF3Dxxxxxx.

CIRCUMVENTION FOR APAR 'MA45738' :
----------------------------------
The circumvention is to perform normal powerdowns of your
system.


Activation Instructions

None.




Special Instructions

This PTF must be permanently applied.

It is suggested that a subset of customers perform an additional B-side
IPL to activate the fixes in this PTF.  To verify if you need to
perform an additional IPL, please do these investigation steps.

1. Sign in to SST system service tools
2. Choose 1. Start a service tool
3. Choose 4. Display/Alter/Dump
4. Choose 1. Display/Alter storage
5. Choose  3. LIC module
6. Choose 1. Find LIC module by name
7. On the "Module name" field type #qsmdprm
8. On the "LIC Module Found", scroll down one screen.
9. Look for the " Data Address . . . :" field and see if the address
is
FFFFFFFF3E xxxxxx.   If you see the FFFFFFFF3E, then you should
perform another IPL so that it completes the move of the
module to a different address.


Default Instructions

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