II_NUM_OF_PROCESSORS
II_NUM_OF_PROCESSORS is set to the number of processors on the machine. The variable affects processing in the DBMS, particularly when waiting for mutually exclusive resources; a value larger than 1 causes a more compute-intensive strategy that may result in getting the resource faster; however, this strategy is not generally advisable on single processor machines.
