Microsoft ODBC for Oracle, Driver is NOT listed

Discussion in 'Windows 64 Bit' started by niladri chatterjee, May 4, 2009.

  1. Ref: O/S Windows XP Pro X64 SP 2 (Ver 5.2 Build 3790)

    Driver comes with the OS itself. I cannot see "Microsoft ODBC for Oracle"
    driver - when I click ADD from ODBC Data Source Administrator, to add a
    ORACLE data source.

    I cannot connect to my Oracle 10g Database. What is my option ?

  2. Is this for a 32-bit or 64-bit client application?

    You need to run the 32-bit ODBC Administrator (in the SysWOW64 folder) to
    manage 32-bit ODBC settings. The default ODBC Administrator accessed from
    Administrative Tools is 64-bit, and only shows 64-bit drivers (for which
    there are a very limited OOB selection).

    Note that both versions of ODBC Administrator have the same executable
    name (ending in 32!).

    If it's a 64-bit client application, then you need to contact Oracle for a

  3. Steve ,

    On the top of my posting in Ref: area I crystal clear I mentioned X64. Is is
    32 bit or 64bit ? ?

    I know how to handle 32 bit. For 64 bit, do I need to contact Oracle ? I
    thought driver comes with the OS itself. OnlyDriver listed is SQL Server 2000.

  4. Windows (XP/Vista/Server) x64 has *two* sets of ODBC drivers, since it can
    run two kinds of application (32-bit and 64-bit). 32-bit applications need
    32-bit ODBC drivers, and 64-bit applications use 64-bit ODBC drivers.
    The only included 64-bit ODBC driver is for MS SQL Server. There are quite
    a few more for 32-bit ODBC (Jet, MSSQL, Oracle among others).

    If your application is 32-bit, you need to configure a 32-bit ODBC source,
    and for that you need to run ODBC Administrator from the SysWOW64 folder,
    rather than from Administrative Tools (since the ODBC Administrator there
    is 64-bit only). There is a 32-bit ODBC driver for Oracle present OOB, but
    Oracle may have a better one anyway.

    If your application is 64-bit, Administrative Tools > Data Sources (ODBC)
    is the right way to go, and if the driver isn't there, you'll definitely
    need to contact Oracle for a suitable driver.
