Users and developers who need to connect directly to our databases can find the most recent tnsnames.ora file on:

Google Drive  (Note that you must have a VT Google account to access the link)

Make sure to download the file to the correct location for your client, which will vary depending on what application you are using and where you installed it.  For example, for a typical SQLPlus installation you would put the file in the ORACLE_HOME/network/admin directory.  If you are unsure, the easiest thing to do is first locate your existing tnsnames.ora.
