Oracle ODBC driver not showing up in Data source administrator

I dont have an entry in registry under ODBC for Oracle. By mistake it got deleted and I'm not able to retrieve the same.
How should I add an entry and enable ODBC driver ?
Any luck?

Are you sure it was there at some point and got deleted? The usual cause for "i dont see the driver in the adminstrator" is that folks have installed 32 bit software on a 64 bit OS and are looking in the wrong administrator.
Assuming the registry keys really did get deleted, you should be fine adding the registry key(s) back in manually.
Alternatively, assuming you're using Oracle's ODBC driver, you could just remove and re-install the driver via the OUI.
If you're looking for Microsoft's ODBC for Oracle though, you'll probably need to resort to fixing the registry manually.
Hope it helps,
Greg

  • Cannot create new Data Source - Oracle ODBC does not show in System DSN

    On Windows 7 x64, Installed Oracle 10g to use ODBC to connect to Oracle database but am not able to create new data source as Oracle ODBC does not show in System DSN.... only shows SQL server etc etc...

    If you installed 32-bit Database Client, try the 32-bit ODBC admin tool: C:\Windows\SysWOW64\odbcad32.exe
    Note that 10.2.0.5 is the earliest "10g" version supported on Win 7.
    http://download.oracle.com/docs/cd/B19306_01/relnotes.102/b15680/toc.htm#BABEBBJF
    As an alternative, try the 11.2 Instant Client.

  • Oracle ODBC driver not register in Windows

    hi,
    i notice that the oracle odbc driver is not register as one of the data source in the windows. Do anyone having this problem too?? and any solutions??
    I've installed Oracle 10.2.0.1.0 on a windows XP platform. When i want to create a data source in the ODBC, i realize that the oracle driver is not there...
    thanks in advance

    hi,
    i've checked, oracle odbc is installed in my machine, but it is not appear in the windows data source ODBC (control panel > administrative tools > Data Sources (ODBC)).
    I've tried to uninstall and re-install, again the oracle odbc is installed in my machine but never appear in the windows data source ODBC. Is there a way to made it appear in the windows manually?
    thanks

  • Oracle ODBC driver not visible in MS SQL server 2005

    Hi all
    I am trying to export a Ms SQL Server table to Oracle and I do not see the Oracle Driver or any of my local drivers.
    Why?

    Pratik, the SQL does not seem right. BTW you can only retreive data via Deski Free hand SQL. Also try to use OLE DB connection.

  • Oracle 817 client not available in ODBC Data Source Administrator pick list...

    I have installed Oracle 817 client on a PC.
    I can see the server, I can see the instance.
    I can log into the instance using SQLPlus with no problem.
    The product I'm using requires an ODBC connection configured in the ODBC Data Source Administrator.
    When I try to configure it in the DSA, Oracle 8 is not in the list.
    HELP!

    I assume you have Windows on the client. The "Drivers" page of the ODBC_DSA should list all installed drivers. You require:
    name= Oracle ODBC Driver
    version= 8.01.07.00 (or something similar)
    company= Oracle Corporation DO NOT USE the Microsoft one.
    If this does not show, then either it was not included in the Oracle Client installation or you have not rebooted after the Oracle Client installation; the ODBC driver is not visible until rebooted.

  • ODBC driver not recognized by Windows ODBC Data Source Administrator

    Using Windows XP Professional with all patches. I installed Oracle 10g Client, then removed ODBC driver and loaded 10.1.0.1.3 ODBC driver. Windows ODBC Data Source Administrator will not see this driver. (It also didn't see the previous driver, which is why I tried the new one.) The driver is in the registry (HKEY_LOCAL_MACHINE: SOFTWARE\ODBC\ODBCINST.INI) properly configured. It was not in the odbcinst.ini (Windows directory) file however, so I manually added it. I found directions on this site to be sure the drivers were loaded in the Oracle home directory, which is where I put them.

    Hi Joe,
    According to your description, after you run C:\Windows\SysWOW64\odbcad32.exe, Access driver is not displayed when you expand HKEY_LOCAL_MACHINE>ODBC>ODBCINST.INI node.
    The issue is caused by wrong path of odbccad32, please make sure that you are using Administrator account or you have administrative privileges, then refer to the following steps:
    Go to Control Panel.
    Click Administrative Tools.
    Right-click Data Sources(ODBC) to open Properties dialog box.
    In Target text box, type  %windir%\syswow64\odbcad32.exe             
    In Start in text box, type %windir%\syswow64, then click OK to  save the settings.
    If you have any more questions, please feel free to ask.
    Thanks,

  • Can not see Oracle ODBC driver in Ms SQL Server 2007

    Hi
    I am trying to export an ms sql server table to Oracle using the Ms SQL Server 2007 export wizard and the only driver I found in the list is Microsoft OLEDB Provider for Oracle.
    I already installed Oracle client and I addedd an ODBC conenction of the datasources Why can I not see the Oracle ODBC driver?

    Which version of Oracle and what kind of Client Install
    Are you sure you did the full Client Install which will have ODBC ?

    Don't use odbc at all for java <-->MySQL. Use the JDBC driver from the MySQL website

  • Could not see Oracle ODBC driver in Windows ODBC

    Hi,
    I have install the runtime version followed by custom->Windows Oracle Interface successfully.
    Any other steps that i have missed out or lack off in installing the Oracle ODBC driver?
    Thanks in advance.
    Tony

    It's not a plot, but it's sneaky.
    I had the same problem when I installed Oracle 10 client. There is a similar issue on the Oracle forum (Re: ODBC Driver Install Problem. Basically, what was happening is a line had been entered in the ODBC Drivers file that contains "@=". Anything following that line is NOT displayed in the ODBC Admin list.
    To fix this problem, open Regedit and export the "HKLM\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers" key to a file. Edit the file to remove the line "@=" and save the file. Delete the registry key, and merge in your updated file.

  • CR Oracle ODBC Driver

    I recently had to reinstall my operating system (Windows XP Pro 32 bit) and applications, which included Crystal Reports. CR was originally setup to access our companies database tables. I also had and ODBC connection setup for CR.
    I'm having trouble finding the right ODBC software to reinstall so that the CR Oracle ODBC Driver 5.0 shows up in the Administrative Tools/Data Sources (ODBC)/ Drivers. The only ODBC driver that shows up is the Microsoft ODBC Driver for Oracle, which won't connect.
    Once I have the CR ODBC Driver, then I just need to configure it in the System DSN, and copy the sqlnet.ora and tsnnames.ora files into C:\oracle\ora92\network\ADMIN, which is where it is located on another computer that can connect.
    Does anybody know which Oracle software would work for the CR driver issue? Is Oracle supposed to be installed prior to CR so the driver shows up?
    It's been several years since this was originallly setup, and not quite sure how to get the CR driver.
    Please help! Thanks for your assistance.

    if u r running the CR in the current user then you can make the ODBC
    in user dsn or System dsn
    you are to select the Microsoft ODBC for ORACLE
    Then at configuration time the Server will be the Service Name which you have entered in the TNSNAMES.ORA File
    eg orcl.
    then user name eg; scott
    then password as scott;
    thne your odbc is created...
    you can work with CR with this odbc
    if your odbc still not working then go for the latest drivers provider for the oracle 10g
    do it
    best of luck..

  • ORACLE ODBC DRIVER INSTALLATION

    I have downloaded Oracle8 client on my windows95 PC. It is showing ODBC driver installed in the installed components list.
    But this driver is not coming up in the drivers list of ODBC Data Source Administrator screen.
    Could any body help me in this regard.
    Thanks in advace

    If you look at the following key in your registry, you should see an entry "Oracle ODBC Driver" with data "Installed".
    HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers
    There should also be a key
    HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\Oracle ODBC Driver
    with various configuration parameters set. If either of these keys is not there, I suspect you'll have to re-install the ODBC driver.

  • MS ODBC or Oracle ODBC driver?

    Can anyone tell me which is the correct driver to use when developing front end MS Access 2003 to retrieve and update data on a Open VMS platform with Oracle 8.1.7.3 database?
    I have serval Access 2000 databases that run on most WinNT or W2K clients with a couple of W2K Dell exceptions. These Access 2000 db's connect to the Oracle database using linked tables and SQL pass-through queries that work with ODBC Manager-DNS system setup using the Microsoft for Oracle ODBC driver.
    Now we are upgrading to Office Pro 2003 so new W2K images have been setup with Oracle 8.1.7 Client. SQL*Plus works on these clients but when I create the System DNS the Access databases return an error "ODBC connection failed". I can however connect with a pass-through query using Oracle's ODBC driver. Not enough time in roll-out plan to change the ODBC connection string in hundreds of Access SPT queries.
    Please help!

    Hi,
    Since 9.2 has been desupported for error correction you will not be able to download that version from OTN. You should ask whoever is providing the training if their is an alternate version you can use. The only versions that you will be able to download from oracle.com is 10.2 11.1, and 11.2.

  • Crystal Report Oracle ODBC driver invalid Thai character display problem

    Hi,
       My server has CR Oracle ODBC 5.1 installed on last week. We have several reports in the servers which called by our Application to export to text file and pdf file. Sometimes, the output (both text file and pdf file) can't display Thai character correctly. The text file show Thai character in question mark and pdf file show in square box. This problem occur randomly and disappear without doing anything. Sometimes the problem occur for an hour and gone but sometimes occur 10-15 minutes and gone. This problem also not happen every days. Once the problem occur, all reports with Thai character will fail.
       However, we have another server installed the same Application, same OS level, same OS patches and same CR Oracle ODBC driver version installed on the same time as above server (the problem server). This server does not have any problems.
       Any suggestions would be appreciated.
    Best Regards,
    Noppadon S.

    Hi Noppadon,
    Thank you for the info. If it happens randomly in their application then it's something they need to debug. Could even be in the ODBC driver.
    I suggest you tell them that because it works sometimes it shows the issue is likely in their software because if it failed all the time then it would be in Crystal dll's. They need to debug the problem, suggest they use tools like Process Monitor from www.sysinternals.com to step through to see where or what part is failing. If they having logging abilities that may help to find out what step is failing and in which API.
    At this point we have no way of determining where the problem is, it's failing in their application and no one but them know what or how they are using CR runtime files.
    If you can duplicate the problem using Crystal Report Designer then it's our problem, if not they have to help you to show us it is a CR issue.
    Sorry we can't be of more help but without know their code we can't suggest anything to try. Suggest they log a call with support here to help them debug the problem if they don't know what to do.
    Thank you
    Don
