APAR Error Description / Circumvention

-----------------------------------------------
SQE queries allocate temporary storage charged to a shared
bucket (bucket 8; *DATABASE Segment Cache), because the created
objects may be shared across jobs when other users or jobs
execute a query.  By attributing the temporary storage to a
shared bucket, it is difficult to identify jobs that are causing
an over-consumption of temporary storage.
Traditionally, administrators would protect against
over-consumption by utilizing the Maximum temporary storage
(MAXTMPSTG) limit set in the job or class.

CORRECTION FOR APAR MA46806 :
-----------------------------
SQE storage charging will continue to be assigned to the
*DATABASE Segment Cache bucket.  However, if the amount of free
space in SYSBASE falls below the Auxiliary storage lower limit
(QSTGLOWLMT) system value, SQE will enforce the MAXTMPSTG value.
When the amount of temporary storage charged to the job plus
the storage allocated by the query exceeds the MAXTMPSTG value,
the job will be held and a CPI112E message sent will be sent to
the QSYSOPR message queue.  This enforcement will not occur when
MAXTMPSTG is set to *NOMAX.

CIRCUMVENTION FOR APAR MA46806 :
--------------------------------
None.
