According to the download info, 10204 odac comes iwth ODBC.. http://www.oracle.com/technetwork/database/windows/downloads/index-101290.html

The Oracle ODBC driver won't be called "Oracle ODBC Driver", it will be named after the home you install it into. For example, "Oracle in OraHome101".

Do you have sqora32.dll in your BIN directory?

Do you have "Oracle In OraXXXX" in your registry under HKLM\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers\ ?

Did you by chance install onto a 64 bit OS? If so, you'll need to look in the 32 bit administrator instead of the 64 bit administrator.

Note that 10.1 has been desupported for quite a while now.. I'd recommend using something more current. 11.1 can connect to a database as far back as 9.2.0.4.

Hope it helps,
Greg

I'm having the same problems...I installed 11.2....I tried the instantclient...still nothing shows up when I create new data source. Only SQL shows up...no oracle....how can add an oracle odbc data source on windows 7?

You need to provide more info:

1) Did you install Instant client from the IC download, or via the OUI?
2) Did you install 32 bit or 64 bit software?
3) Is the OS 32 bit or 64 bit?
4) does Sqora32.dll exist in the Oracle home?

Thanks

Hi, I've the same problem.

I've installed the client via OUI.

The setup I've downloaded is a 32-bit installer, but my system is Windows 7 Professional 64-bit, and ye, the file Sqora32.dll exists in my Oracle Home.

Hi.

I am also having this problem. EDIT: Not having this problem anymore...
I have Windows 7 64bit Ultimate.
I have tried downloading both the 64bit and 32bit installation packages, and there is no change.
The only driver showing in Reg: HKLM\Software\ODBC\ODBCINST.INI\ODBC Drivers is the default SQL server.
I've been installing the 11.2 version of Oracle, both the full package with ODBC and the instant-client with ODBC.
None is giving me a selectable ODBC driver in Windows...
EDIT:
I just checked the HKLM\Software\Wow6432Node\ODBC\ODBCINST.INI\ODBC Drivers
And there were a lot of drivers there.
And I found them when i started the odbcad32.exe from c:\windows\SysWOW64 (Had to be started from the folder, and not from run only)

user3029590,

have you also found a solution to use these ODBC drivers?

the ODBC Administration you need to use is the 64 bit version. The 32 bit version that you are probably using does not know how to connect you to your database (which is why you are not seeing the driver in the -32 bit- list). Navigate to C:\Windows\SysWOW64\odbcad32.exe . Use that and your driver should pop up when trying to create a System DSN. (I pulled my hair out for a few hours looking for this answer - I hope it's what you needed).

Just to clarify, the odbc admin in c:\windows\syswow64 is the *32-bit* administrator. The odbc admin in c:\windows\system32 is the 64 bit administrator. Kinda bad naming convention there huh? :)

Hello,
I am trying to use Access 2007 on Windows Server 2008 R2 64 to access an Oracle database.

I have installed client 10.2.0 which is visible from odbcad32.exe in C:\Windows\System32, however I need to see the client from C:\Windows\SysWOW64\odbcad32 since that is where Access gets the System DSN I need.

How can I get the SysWOW64 data source to list the Oracle ODBC driver? I fear I have screwed too much up in forum advice!

Thanks for your help!

C:\Windows\SysWOW64\odbcad32 is the 32 bit odbc admin, and you get drivers to show up it by installing 32 bit odbc drivers/software.
If you see the driver in C:\Windows\System32 on a 64 bit OS, you have 64 bit oracle client software.
Add a 32 bit home.

Greg

Thank you so much! I was having a similar issue with the 32bit drivers on a 64bit system. WHY on earth Microsoft named its 64bit driver manager AND the 32bit manager the same name is beyond me. Ran the odbcad32.exe from SysWOW64 and my oracle drivers were there!

i am using windows-7 64 bit.
i did whatever you told here.
test connection was successful but when i used in code it didnt work ,its showing ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.please help

nkulu1,

I do the same thing you do. What I have found is:

1) it is best to compile and run my VB.NET (& C#) apps as 32 bit apps (even though they are running on 64 bit Windows 7).
2) Install the 32 bit version of 11gR2 (http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html and download the “Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64)”.
3) Use the 32 bit version of ODBC Administrator (C:\Windows\SysWOW64\odbcad32.exe) as the default 64 bit version won't see 32 bit drivers.

When I tried to write my app to work only using the 64 bit drivers, it didn't work. The answer I got was that I was using libraries that only worked in 32 bit mode. As I am only using the Oracle ODBC drivers, I wasn't sure what I was using that caused the problem, but when I compiled and ran in 32bit mode it all worked on the win 7 systems. End users can not tell any difference between the 32 bit version and the 64 bit version except that the 32 bit version doesn't crash the way the 64 bit version did.

Take care,

Did you get a fix for this ? I am also facing the same issue. Pls post the fix if you ever got one. Thanks.

Does anyone have any solutions to this? I am having a similar issue. Thanks.

I had the same problem. You must run the 32-bit ODBC Admin tool and the 32-bit drivers will show up. Since I was running Windows 7 64-bit, the default ODBC Admin tool only shows the 64-bit drivers. Here's the location of the 32-bit ODBC Admin tool: C:\Windows\SysWOW64\odbcad32.exe

Double-click to run it and then select the "Drivers" tab. You will see the list of drivers.

Hi, I am facing similar issue:

Downloaded Oracle ODBC driver
Oracle 10g Release 2 ODAC
Download the File
ODAC1020221.exe 206 MB (216,841,603 bytes)

As well as tried with -
Oracle 10g ODAC
Download the File
ODAC101040.exe (174MB)

However in both cases the driver does not show up in the Datasource drivers list.

I am trying to install it on Win 2008 Server R2 (6.1) (I think 64bit) however connecting via a 32-bit application to Oracle10g

ANy help will be highly appreciated.

Thanks,
Kunal

Just started testing Instant Client 11g, I had to run odbc_install.exe from the Oracle directory before it would show up in ODBC data source.

Just wanted to share my finds and what I had to do.

Basically my issues was not seeing the ODBC Driver on Win 2008 R2 (which is a 64Bit O/S) for Oracle 10g and Oracle 11g while I made sure the Windows ODBC Driver was installed from the Custom Install to make sure they were installed.

On that note:

Confirm the following:

1. Are the entries in the registry?
- Check in *"HKLM\Software\Wow6432Node\ODBC\ODBCINST.INI\ODBC Drivers\"*
to see if the 'Oracle in ....' is in there, if it is you have installed the ODBC driver so you are good however if you don't see them in there make sure you install the ODBC Driver from the Oracle Installation you ran originally.

2. Make sure you are using the 32-bit ODBC Admin tool as mentioned in the replies here.
- Found in C:\Windows\SysWOW64\odbcad32.exe
Once you launch this and check the Drivers tab, you will probably notice it's EMPTY and that is our problem!

Now the trick here is this:

You HAVE to launch that tool as Administrator in order for the registry information to be written out and displayed in the ODBC Tool. So, run the odbcad32.exe by Right Clicking and picking Run as Administrator_, once this is done you will be set!

This is a one time step to run as administrator, it will register the whole registry list and you should see a whole list of Drivers now under the Driver Tab including the Oracle ODBC drivers.

Hope this helps, it helped me...
Later
