Hi,
My experience on Solaris with Oracle 9i is that it looks in
$ORACLE_HOME/network/admin first, but I am sure that different ports vary,
despite what the manual say. I suggest using truss on a tnsping or sqlplus
session and studying the ouput for open commands to see what order the
search takes place in for the tnsnames.ora file.

Regards

Pete

ERROR at line 2:

COUNT(*)
-- ---- --
3

QUESTION:
The tnsnames.ora is in the default location and it is not found until
TNS_ADMIN is set. How do I find out where TNS_ADMIN is pointing at the
system level, if there is such a thing ? Why do I have to set TNS_ADMIN at
the session level ?????

TIA,
