The first parameter, the maximum number of semaphores per array (SEMMSL), is the most significant for this discussion. This value is related to the maximum number of connections, with some allowance for TimesTen internal connections. The second parameter is maximum semaphores systemwide (SEMMNS), the third parameter is maximum operations per semop call (SEMOPM), and the fourth parameter is maximum arrays (SEMNI).
