IC75315: HISTORICAL ANALYSIS OF A TABLESPACE HAS TOTAL SIZE SHOWING AS NEGATIVE VALUE IN CONTROL CENTER

APAR status

  • Closed as program error.

Error 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.
    

Local fix

  • As a workaround, please calculate the Total Size manually using
    the calculation noted in the error description.
