Home -> Community -> Mailing Lists -> Oracle-L -> Rogue TNSNAMES.ORA files Revisited
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. :-)
Hope that information is useful to someone out there.
