APAR Error Description / Circumvention

-----------------------------------------------
In some environments, the System Limits pruning task which runs
in a low priority QDBSRVnn job can consume an undue amount of
CPU while executing this DELETE SQL statement:

DELETE FROM QSYS2.SYSLIMTBL
WHERE LIMIT_TYPE = 1 AND
LASTCHG NOT IN (SELECT LASTCHG FROM QSYS2.SYSLIMPRNO)

CORRECTION FOR APAR SE57865 :
-----------------------------
The QSYS2.SYSLIMPRNO view contained a union of two OLAP queries.
By splitting the two OLAP queries into individual views, SQE is
able to achieve a much better performance implementation.

CIRCUMVENTION FOR APAR SE57865 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS IS A DELAYED PTF TO BE APPLIED AT IPL TIME.
