I have oracle db server 9.2.0.2 , I have a client connected with this server, the client has sqlplus 8.0.6.0 

I adjust the tnsnames in the client with the following parameters :


myconn =

  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = my_sid)
    )
  )


this connection was successfull 

when I tried the same connection with oracle db server 11g (11.2.0.1) 

this connection failed
