Oracle 11g R2 to MS Access .mdb (Windows Server 2008 64-bit) problem

Question

I have a need to make connection from Oracle 11g R2 to MS Access database file (mdb). OS is MS Windows Server 2008 64-bit. My configuration is next:
1. I made System DNS mikeacs (using c:\windows\sys_wow6\odbcad32.exe) to my access mdb file;
2. I made initmikeacs.ora file in ora_home\hs\admin folder:
# HS init parameters
HS_FDS_CONNECT_INFO = mikeacs
HS_FDS_TRACE_LEVEL = debug
HS_FDS_SHAREABLE_NAME = c:\Windows
3. Listener.ora file is:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\Oracle\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\Oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
(SID_DESC =
(SID_NAME = mikeacs)
(ORACLE_HOME = c:\oracle\product\11.2.0\dbhome_1)
(PROGRAM = dg4odbc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = cspo02)(PORT = 1521))
4. Tnsnames.ora is:
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
MIKEACS =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=cspo02)(PORT=1521))
(CONNECT_DATA=(SID=mikeacs))
(HS=OK)
5. After this, I restarted Listener:
lsnrctl stop;
lsnrctl start;
Given feedback:
STATUS of the LISTENER

The command completed successfully
6. I created db link: create public database link macs using 'MIKEACS' (connected as sysdba);
7. tnsping mikeacs:
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=cspo02)(PORT=1521)) (CONNECT_DATA=(SID=mikeacs)) (HS=OK))
OK (0 msec)
Then, when I try fire query (connected as sysdba): select * from mytable@macs;
get result:
ERROR at line 1:
ORA-28513: internal error in geterogeneous remote agent
ORA-02063: preceding line from MACS;
Although, when I fire the same query, but connected as other user, get next result:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][ODBC Driver Manager] Data source name not found and no default
driver specified {IM002}
ORA-02063: preceding 2 lines from MACS
Where is my problem? Please help. Thanks in advance!

Answer 1

That's the problem. DG4ODBC on 64bit Windows is 64bit and thus it also requires a 64bit ODBC driver.
If you don't find one - maybe you can install DG4ODBC 32bi on a 32bit platform (please do NOT install it on the 64bit Windows machine) and then use this 32biit DG4ODBC with the 32bit ODBC driver.
Another option would be to purchase a commercial ODBC driver or a bridged ODBC driver.
