Oracle ODBC Connection: TNS Problem?

Question

Hello!
I'm trying to connect to a Oracle Database from a 64bit Linux machine.
I'm using instantclient 10.2.0.4 64bit and oracle odbc driver.
Here are all files and env variables, i created:
ODBCINST.INI
[Oracle]
Description = Oracle Driver
Driver = /usr/lib/libsqora.so.10.1
UsageCount = 2
ODBC.INI
[DS1]
Description = DS1
Driver = Oracle
Trace = Yes
TraceFile = sql.log
Database = //111.11.11.111:1111/db1
User = user
Password = pass
LD_LIBRARY_PATH = :/usr/lib/oracle/10.2.0.4/client64/lib
SQLPATH = /usr/lib/oracle/10.2.0.4/client64/bin
I also had edited the SQLConnect.c and isql.c: http://sourceforge.net/tracker/?func=detail&aid=2260937&group_id=1544&atid=351544
If i'm tring to connect to the database ( isql -v DS1 user pass ), i'm getting this error message:
[S1000][unixODBC][Oracle][ODBC][Ora]ORA-12162: TNS:net service name is incorrectly specified
I found a nice work-around for this problem:
export TWO_TASK=//111.11.11.111:1111/db1
After this change, i can connect to the database...
But this means, all oracle connections are trying to connect to THIS server, right? But i need more then one server possibility...
Any ideas?
Thanks, mdo.

1. Using MS Access, follow the process to link tables from the Oracle
database using the user account you wish to restrict, until the list of
attachable objects is shown.
2. Note the tables that appear in the list. You should see a long list of
tables owned by multiple schema owners.
3. Without linking any tables, close the Link Tables dialog box.
4. Create an ALL_OBJECTS view and ALL_SYNONYMS view in the user's schema in
which you used to log into the database.
For example:
CREATE OR REPLACE VIEW SCOTT.ALL_OBJECTS AS
SELECT * FROM SYS.ALL_OBJECTS
WHERE OWNER IN ('SCOTT');
CREATE OR REPLACE VIEW SCOTT.ALL_SYNONYMS AS
SELECT * FROM SYS.ALL_SYNONYMS
WHERE OWNER IN ('SCOTT');
5. Using MS Access, again follow the process to link tables from the Oracle
database using the user account from above to log in.
6. Note the tables that show up in the list. The only tables listed should
be those owned by the schema owner specified by the views, if the example
statement above is used.
--NOTE that this technique has the limitation that only objects actually
owned by the view user will be viewable. For example, if the user has
a synonym that points to an object in another user's schema, it will not
be visible
