Hi, i wonder if someone knows how Oracle resolves the hostnames which are included inside
the tnsnames.ora? It happened to me several times that Oracle (tnsping) couldn't resolve
them but it worked if we replaced the hostname with the IP-Address of the server (there where
no such problems with 'nslookup ').

(At the moment we have a comparable problem where Oracle couldn't resolve either the hostname
nor the IP-Address but nslookup works without problems - but it seems to me that this server with the corresponding IP-Addresses wasn't a clean setup.)

Nevertheless it would be interesting to me if someone could give me some more information.

The database versions is 8.1.6/8.1.7 on HP-UX 11.0 (64 bit).
