Comment: Automatic logins by PC, Apple MacIntosh, and OS/2 users are not considered to be secure. A user could edit the Oracle configuration file and change their user ID at will. For security reasons, if users of these systems are logging in over the network, Oracle Corporation strongly recommends you disable the ops$ logins in the listener.ora file.
