db2exfmt outputs HEAPUSE : (Maximum Statement Heap Usage)
when the memory size is greater than 2GB, we see a negative
number.
It has platform-dependent behaviour. On AIX, there is negative
number.
Arguments:
---------
BLDLEVEL: (Build level)
DB2 v9.5.0.4 : s090429
HEAPUSE : (Maximum Statement Heap Usage)
-190800 Pages
On linuxamd64, the behaviour is different. Instead of a negative
number, db2exfmt outputs an extreamly large number
Arguments:
---------
BLDLEVEL: (Build level)
DB2 v9.5.0.4 : s090429
HEAPUSE : (Maximum Statement Heap Usage)

The wrong "HEAPUSE" info is stored in the EXPLAIN tables, any
program that queries the explain tables may see the incorrect
HEAPUSE. | |
