APAR Error Description / Circumvention
-----------------------------------------------
When determining how many pages the expert cache ager tasks has
aged, a count of aged pages before it runs is subtracted from
the count of aged pages after it runs. The code that calculates
the number of aged pages, must sum a count of aged pages for
each physical processor. As systems grow larger this can take a
substantial amount of time, as the method will be called very
frequently and have more numbers to sum.
CORRECTION FOR APAR MA47872 :
-----------------------------
We will change the code to return the number of pages aged by
the method, eliminating the need to sum before and after it is
called.
CIRCUMVENTION FOR APAR MA47872 :
--------------------------------
None.
