APAR Error Description / Circumvention

-----------------------------------------------
Running an internal performance benchmark shows performance
degradation due to increased IO and gate contention.

CORRECTION FOR APAR MA45729 :
-----------------------------
Journaled object information was being written to disk too
aggressively. This change reduces the amount of journaled object
information being written.

CIRCUMVENTION FOR APAR MA45729 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
