hello,



which system call is used to measure wait time ?



I guess following method is wrong:



t0 := get_time_from_v$timer;


wait();


t1 := get_time_from_v$timer;


wait_time := t1 - t0;



wait_time may show wrong becasue CPU may be still used by process
during wait() because of tight loop or OS timer signal SIGALRM to check
resource is available.



regards...
