That doesn't get rid of anything, except a SID_LIST in Listener.ora. You still need a Listener.Ora to tell the Listener what name it should have and what port it should listen on -unless you are happy to accept the defaults, which are severely restrictive for most practical purposes.

This statement just isn't true. Oracle Names is actually going to be de-supported (yup, it's *that* much better than tnsnames), and in the meantime it is only doing what tnsnames.ora does, but on a larger scale. The magic point being the words 'larger scale'. When you've a couple of dozen clients to configure, automated distribution of tnsnames to PCs is probably far easier than building a Names infrastructure. Beyond that number, Names or similar LDAP-compliant technologies have compelling management advances, true. But Oracle nowehere promotes Names as a 'preferred' solution, and tnsnames as a 'deprecated' one. They each have their niches.

Precisely. I don't see /etc/hosts going anywhere soon, do you? And why not, indeed? For a dozen PCs, hosts is a perfectly reasonable solution, and no-one would seriously suggest that anyone was "trying to get rid of it". Horses for courses.
