Error 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
    

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.
