APAR Error Description / Circumvention

-----------------------------------------------
When destroying an object secured by an authority list, or
adding a new object to an authority list, the authority list is
damaged and/or an MCH2804 (Tried to go larger than storage limit
for object) is received.

CORRECTION FOR APAR MA39498 :
-----------------------------
If two or more processes access an authority list
simultaneously, and it is the first time the authority list is
accessed after an abnormal IPL, there exists a small timing
window where one of the processes can have an incorrect value
set, causing an exception and subsequent damage of the authority
list to occur.  The race condition has been removed.

CIRCUMVENTION FOR APAR MA39498 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions
