Thanks, John.

Just out of curiousity - for those of us who aren't Unix experts - what
options did you use for truss to obtain that info.??

Brian,

The order in which the TNS connection searches are performed can also
easily
be determined by using the 'truss' command on Solaris. I used this to
prove
my case to a PHB of a smart-aleck Developer who was side-stepping our
move
to an Oracle Name Service in a prior assignment.

I see what you mean - been there done that!

Take care bro!

I don't know what the future holds for me, but I do know who holds my
future!

A few days (or was that weeks??) ago, someone posted some problems they
were
having connecting to a database defined in their tnsnames.ora file.  The
problem was resolved when they found out that there was a 'rogue'
tnsnames.ora file residing in the same directory as the binary.  The
binary
file was resolving a database's address by using the local tnsnames.ora
first.
 
I recently had a similar issue (a long story, available on
http://www.clanmcgraw.com/oracle.html for those interested) where
sqlplus
was resolving a database address by using a tnsnames.ora file stored in
/var/opt/oracle (on Solaris 8).  I thought that was because I did not
have
the TNS_ADMIN environment variable set properly by the oraenv file.
 
I did some research on Metalink, and under Note 114085.1, found the
following information that others might find useful:
Windows NT/2000 running Oracle 9i 
    First: The directory where the application is launched.  For
example, if
sqlplus resides in 
            ORACLE_HOME\bin\sqlplus but was launched from the c:\temp
directory, then 
            c:\temp is searched for a tnsnames.ora file. 
    Second: The value of the TNS_ADMIN environment variable. 
    Third: ORACLE_HOME\network\admin 
Sun Solaris running Oracle 8i or 9i 
    First: The oracle user's home directory is searched for a hidden
'.tnsnames.ora' 
    Second: The value of the TNS_ADMIN environment variable. 
    Third: /var/opt/oracle 
    Fourth: $ORACLE_HOME/network/admin 
Some were talking about an April Fool's joke with local tnsnames.ora
files.
I think you'd have a lot more fun with the .tnsnames.ora file, if you're
on
Solaris.  J
 
Hope that information is useful to someone out there...
 
Brian
