You can set inbound_connect_timeout for all connections via a particular TNS_ADMIN or a particular listener, but not for a specific user. http://download.oracle.com/docs/cd/B19306_01/network.102/b14212/performance. htm#sthref1422 http://tinyurl.com/ys2wc8 Obviously, if the connection is being initiated, then the user is not logged in yet. Therefore it is illogical to hope to apply a connection limit to a specific Oracle user. You could direct an OS user to a specific listener that has a timeout set using the TNS_ADMIN variable.
