APAR Error Description / Circumvention

-----------------------------------------------
When evaluating collection services data to determine the hit
ratio of the SQE plan cache,  the statistics did not match the
values externalized by the QQQOOOCACH interface with the D:D
output. Collection services fields SQPROBES and SQNOMATCH from
data file QAPMSQLPC seem to not be correct.

CORRECTION FOR APAR MA48760 :
-----------------------------
During a full open of a SQL query, the SQE plan cache is
searched for an existing plan to avoid an SQL optimization. If
no matching plan is found and an optimization is required, an
internal static variable is incremented for statistical
purposes. The static variable is accessed when the collection
service data is collected. Unfortunately, this static variable
is not always set correctly. The PTF will correct this problem.

CIRCUMVENTION FOR APAR MA48760 :
--------------------------------
None.
