Yes, that is a sensible way to do what you want.

For your purposes, you don't need to worry about either. You don't
need to pick a port number for each of your processes to listen on
since the operating system will pick a suitable one for you.

If you _did_ want to choose a particular port to listen on (so that
IORs are identical between separate runs for example), you use the
-ORBpoa_iiop_port option.

-ORBInitialPort is now deprecated. It tells the _client_ side where to
find a bootstrap agent which is used by resolve_initial_references().
The interoperable naming service adds a portable way to do the same
thing.

All these things are described in chapter 6 of the omniORB 3 manual,
which you'll find in the doc directory of recent check-outs.

Cheers,

Duncan.
