DB2 - Problem description

Problem IC75280 Status: Closed

HISTORICAL ANALYSIS OF A TABLESPACE HAS TOTAL SIZE SHOWING AS NEGATIVE
VALUE IN CONTROL CENTER

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
The calculation for Total Size is: 
Total Size(in bytes) = totalPages in bytes (the value being 
shown at the Historical Analysis Screen) * pageSize in bytes 
(the value being shown at the Historical Analysis screen) 
 
Total Size (in MB) = Total Size (in bytes) / MB unit 
 
In cases where Total Pages is very large, this calculation can 
result in a very large number which displays as a negative 
value.  This is because an integer type is being used to store 
the total page value and the value is too large for the integer 
type.
