-x tcpip,ipx
allows only TCP/IP and IPX communications.
The default is to try all settings supported by the database server on your operating system.
For some protocols, you can provide additional parameters, in this format:
-x tcpip(PARM1=value1;PARM2=value2;...)
For UNIX, quotation marks are required if more than one parameter is supplied:
-x "tcpip(PARM1=value1;PARM2=value2;...)"
