Using Oracle Generic Connectivity to connect from Oracle to Microsoft Acces

Question

I am trying to connect from Oracle to Access using ODBC. I followed the steps described in oracle documentation but was not sucessful. Could you plase take a look at my code let me know where I went wrong. It is as follows :
1)Created an ODBC connection for Microsoft Access called 'MSACCESS' (System DSN). And associated accdb1.mdb to this ODBC connection.
2)Created a table called orders in accdb1.mdb.
3)Added the foll lines in tnsnames.ora
accdb1 =
(DESCRIPTION=
(ADDRESS=
               (PROTOCOL=tcp)
               (HOST=kdandapani.170systems.com)
               (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=accdb1)
(HS=OK)
4)added the following lines in listner.ora :
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME=accdb1)
(ORACLE_HOME=c:\orasrv)
(PROGRAM=accdb1)
5) Copied inithsodbc.ora to iniths_accdb1.ora in the ORACLE_HOME/hs/admin directory. Added the following line there :
HS_FDS_CONNECT_INFO = MSACCESS
6)Created the foll dblink :
create database link access1
using 'accdb1';
7)tried to access table ORDERS in the MSACCESS database with the foll SQL -
select * from orders@access1;
Resulted in the foll error message
ERROR at line 1:
ORA-12154: TNS:could not resolve service name

hi,
I am new to Generic Connectivity i have just followed all the steps you wrote once in this forum but i m getting the following error :
SQL> SELECT * FROM LOGIN@MSACCESS;
SELECT * FROM LOGIN@MSACCESS
ERROR at line 1:
ORA-28509: unable to establish a connection to non-Oracle system
ORA-02063: preceding line from MSACCESS
Following are the steps you suggested in this forum :
1)Created an ODBC connection for Microsoft Access called 'MSACCESS'. And associated accdb1.mdb to this ODBC connection.
2)Created a table called ORDERS in accdb1.mdb.
3)Added the foll lines in tnsnames.ora
MSACCESS.170SYSTEMS.COM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = kdandapani.170systems.com)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = MSACCESS)
(HS = OK)
4)This is how the listner.ora looks after I added SID_NAME=MSACCESS :
# LISTENER.ORA Network Configuration File: c:\orasrv\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = kdandapani)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ORALOCAL)
(ORACLE_HOME = c:\orasrv)
(SID_NAME = ORALOCAL)
(SID_DESC =
(PROGRAM = extproc)
(SID_NAME = PLSExtProc)
(ORACLE_HOME = c:\orasrv)
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = MSACCESS)
(ORACLE_HOME = c:\orasrv)
5) Copied inithsodbc.ora to iniths_MSACCESS.ora in the ORACLE_HOME/hs/admin directory. Added the following line there :
HS_FDS_CONNECT_INFO = MSACCESS
6)Created the foll dblink :
create database link MSACCESS
using 'MSACCESS';
7)tried to access table ORDERS in the MSACCESS database with the foll SQL -
select * from orders@MSACCESS;
I have used my login table instead of orders. But i got an error that i have stated earlier.
