interactive capacity to purchased levels.  This PTF may be a prerequisite

APAR Error Description / Circumvention

-----------------------------------------------
Queries having numerous predicates may fail to run and may
produce an accompanying MCH0601 message F/DbListHome
T/QQQOOODBOP. A related 0600 BADD LIC log referencing module
DbListHome and entry appendNoLock__6DbListXTPvSP4_FRCPv  will
accompany the failure. The failure may appear to be
intermittent. Other jobs may be affected with unpredictable
failures subsequent to this failure.

CORRECTION FOR APAR MA45683 :
-----------------------------
The SQL optimizer incorrectly allocated storage for certain
internal structures when processing queries with complex
predicates. The incorrect behavior permitted other memory
locations to be changed unexpectedly. This led to the errors
described above as well as to unpredictable behavior across the
system including, potentially, system crashes. This fix corrects
the storage allocation for the internal structures and enables
the queries to run successfully.

CIRCUMVENTION FOR APAR MA45683 :
--------------------------------
None.
