Hi,
Al,
The order should be this :

$TNSNAMES (if set)
/etc
$ORACLE_HOME/network/admin

I think you may have a stray tnsnames.ora in your /etc directory.

Cheers,
Mike

Group,

              from ses_army_at_csucmis;
              from ses_army_at_csucmis

              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 ?????
