Interesting. According to this test the first place Oracle looks (on AIX
5.2) is under my home directory (executing from subdirectory) for a hidden
version of the tnsnames.ora file, then to /var/opt/oracle, and finally to
/etc where the installation manual said to store the file.

In the past, when I 've been confused about where my
system was getting a particular connect string definition,
I 've found it can be useful to do something like:

truss tnsping problem_connect_string 2 >&1 | grep tnsnames

And this will give the order that things are searched, and
which was the first to succeed.
