    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = test)
      (SERVER=SHARED)
SQL> show parameter mts
NAME                                 TYPE    VALUE
mts_circuits                         integer 170
mts_dispatchers                      string  (protocol=tcp)(dispatchers=2)(
                                             connections=500)

mts_max_dispatchers                  integer 5
mts_max_servers                      integer 20
mts_multiple_listeners               boolean FALSE
mts_servers                          integer 2
mts_service                          string  test
mts_sessions                         integer 165
SQL> conn scott/tiger@test
