RE: Orace setting on NT

On Nt, you can define tns_admin by right clicking on "my computer" and going to the properties.
You can also define the variable in a command window: set tns_admin=path.  Oracle will also use a tnsnames file if it exists in the current directory (or in the start in directory used by the short-cut),

I think there is probably a hierarchy of sorts so that if the alias isn't found in the tnsnames in the current directory, it will look at the one in network\admin...

Afaik on NT or 2k oracle uses only one tnsnames.ora file its located in

$ORAHOME\network\admin

There is a sql.net file that dictates the precedence of files eg tns onames

Eg sql.net

# Generated by Oracle configuration tools.

SQLNET.AUTHENTICATION_SERVICES= (NTS) NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME) Here oracle looks for the tnsnames then onames.... Then finally hostname
