DB2 - Problembeschreibung

Problem IC79401 Status: Geschlossen

MAXOFFLINEREORGTABLESIZE IS LIMITED TO 4194303 (DEC) KB

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
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

Local-Fix:
1) Set maxOfflineReorgTableSize to 4194303 and reorg tables 
bigger than this manually. 
 
or: 
 
2) Set the maxOfflineReorgTableSize criteria to 0, to disable 
it. It must be noted that if this is set to zero, all table 
sizes will be considered for evaluation.
