SET ATTEMPTS = 1
Or, can this be done on the command line? ie.,
SQLPLUS> ALTER PROFILE DEFAULT FAILED_LOGIN_ATTEMPTS = 1;
The DEFAULT profile is always
active, at least the PASSWORD limits are
if not the KERNEL limits.
If this doesn't need to apply to all users,
then create a new profile
with the desired setting and ALTER USER to
set that new profile to their
accounts.
