set breakeven — Set the breakeven parameter - used within the cost calculations.
set breakeven
<breakevenPara>
The breakeven parameter has to be a positive number
smaller than 1.0. It specifies the impact of the age of
the least recently used
file on space cost. It the LRU file is one
week old, the space cost will be equal to (1 +
breakeven)
. Note that this will not be true,
if the breakeven parameter has been set to a value
greater or equal to 1.
The breakeven parameter is used within the space cost calculation scheme described in the section called “The Space Cost”.
