Problem IC79401
|
Status: Closed |
MAXOFFLINEREORGTABLESIZE IS LIMITED TO 4194303 (DEC) KB |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Currently due to an overflow while converting the value
specified for maxOfflineReorgTableSize, the maximum possible
size is 4194303 (dec) KB.
Details:
With the policy value of maxOfflineReorgTableSize="52428800",
when multiplied with 1024, it does a 32 bit multiplication which
leads to overflow.
52428800 * 1024
= dec 53687091200
= hex C80000000
= bin 110010000000000000000000000000000000
only the least significant 32 bits were considered.
The maximum value it can be set in the policy without
overflowing 32 bit would be
FFFFFFF(hex) divided 1024 (dec)
= 4194303 (dec) KB << This would be the maximum value that
maxOfflineReorgTableSize can have
= 3.9 GB approx |
