Andrew,
Why don’t you use LDAP servers for the names resolution? It is the real
centralized solution. Not only does it save you of trouble with deployment of
tnsnames.ora, but any change to a connection string is instantaneously visible
to all of the database clients.
If Active Directory is not a viable solution in your organization, you can
setup your own Oracle Directory Server (ODS) for this purpose. For me, ODS is
one of the key enabler of the agility in database provisioning.

Subject: Re: sys_context to get connection string?
And even assuming they use dns, it only 'centralizes' the host name. I prefer
to centralize the database connection definitions. With a single tns, i can
simply tell users that if they dont use the centralized tnsnames.ora file I
will decline they are entirely on their own in defining their connections from
the desktop.
On another subject, has anyone else noticed that dgmgrl can be inconsistent as
to whether it is using the tnsnames.ora file from the database home or the asm
home? It might just be with the ODA (unlikely) but working with one recently I
found occasions when it used the db home tnsnames.ora and other occasions where
it uses the asm home tnsnames.ora.

Does it Malden? I have a funny feeling that the host part of an ezconnect
string is permitted to be an IP address. No DNS required. :-(
Cheers,

anything it decentralizes everything.
EZCONNECT relies on DNS, which is usually centralized.
