APAR Error Description / Circumvention

-----------------------------------------------
Complex OLAP queries running concurrently can consume excessive
amounts of segment storage which can lead to storage problems on
the system. It is also the case that this code path is not
interuptable so the optimizing query can not be ended.

CORRECTION FOR APAR MA47049 :
-----------------------------
This PTF will ensures that this code path is interuptable. It
also eliminates unnecessary storage allocations which should
have a positive affect on the overall system storage.

CIRCUMVENTION FOR APAR MA47049 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
