SETTING UP THE ODBC ORACLE DRIVER FOR USE WITH THE SQL*NET FOR WINDOWS DLLs

This file discusses how to set up the ODBC ORACLE driver to run with your 
ORACLE Server software. To use the ODBC ORACLE driver with any large 
application, such as Microsoft Access, you must use the SQL*Net for Windows 
DLLs. Because the ODBC ORACLE driver is designed to use ORACLE Server 
version 6 and the SQL*Net for Windows DLLs are designed to use ORACLE Server 
version 7, you must be careful to configure your system correctly.

If you do not have the SQL*Net for Windows DLLs, or, after following the
instructions in this file, you are still unable to connect to ORACLE Server
with SQL*Net, you can contact Oracle Corp. at 1-800-345-DBMS.


If ORACLE Server version 6 is already installed on your system
--------------------------------------------------------------

To set up the ODBC ORACLE driver and the SQL*Net for Windows DLLs if you 
already have ORACLE Server version 6 on your system:

1.  Make sure you have the correct versions of ORACLE products, including at 
    least one SQL*Net protocol.

    Product                                  Version
    --------------------------------         -----------
    ORACLE Installer                         3.0.8.3.7
    Required Support Files                   7.0.12.1.0
    SQL*Net Named Pipes for Windows          1.1.1.3
    SQL*Net SPX for Windows                  1.1.1.5
    SQL*Net TCP/IP for Windows               1.1.7.6

2.  Test your current SQL*Net connection by using an ORACLE tool such as 
    SQL*Plus for Windows.

3.  Search for and delete all copies of ORA6WIN.DLL from your system. A new
    (backwards compatible) version of ORA6WIN.DLL will be installed with the
    ODBC ORACLE driver.

4.  Run the ORACLE Installer program. When asked for your ORACLE installation
    directory, use the suggested default directory C:\ORAWIN.

5.  Run the ORACLE Installer in the ORACLE group in the Program Manager:

    a) Install the files from the Required Support Files disk.

    b) Install the SQL*Net protocol you will be using. For more information,
       see the ORACLE documentation.

6.  If the following line exists, remove it from your AUTOEXEC.BAT file:

      SET CONFIG=<oracle_configuration_file>

    Add the following line to your AUTOEXEC.BAT file:

      SET CONFIG_FILES=C:\WINDOWS\ORACLE.INI

    NOTE: If you are using the MS-DOS 6.0 operating system, add the following 
    line to the end of your AUTOEXEC.BAT file:

      SET CONFIG=

    ORACLE Server first checks the CONFIG environment variable for the path of
    the ORACLE configuration file. If the CONFIG variable is not set, ORACLE
    Server checks the CONFIG_FILES variable. Because MS-DOS 6.0 can use the 
    CONFIG environment variable during system startup, you must clear this 
    variable before leaving your AUTOEXEC.BAT file. Otherwise, ORACLE Server 
    will use its value as the path of the ORACLE configuration file.

7.  Make sure your PATH variable includes the BIN subdirectories of your
    <oraclehome> directory and the \ORAWIN directory. For example, if your
    <oraclehome> directory is C:\ORACLE6, add the following line to your
    AUTOEXEC.BAT file:

      SET PATH=%PATH%;C:\ORACLE6\BIN;C:\ORAWIN\BIN

8.  Paste the contents of your CONFIG.ORA file at the start of your
    ORACLE.INI file. For example, if your CONFIG.ORA file contains:

      LANGUAGE=American_America.US7ASCII
      ORACLE_HOME=C:\ORACLE6
      MACHINE_TYPE=J
      SQLPATH=C:\ORACLE6
      WIN_REMOTE_SESSIONS=3
      LOCAL=p:MyServer

    and your ORACLE.INI file contains:

      [Oracle]
      ORACLE_HOME=C:\ORAWIN
      LANGUAGE=American_America.US7ASCII
      NLS_LANG=ENGLISH
      WIN_LOCAL_SESSIONS=1
      TCP_VENDOR=LANMAN
      TCP_SERVICES_FILE=C:\WINDOWS\SERVICES

    then your modified ORACLE.INI file should contain:

      LANGUAGE=American_America.US7ASCII
      ORACLE_HOME=C:\ORACLE6
      MACHINE_TYPE=J
      SQLPATH=C:\ORACLE6
      WIN_REMOTE_SESSIONS=3
      LOCAL=p:MyServer
      
      [Oracle]
      ORACLE_HOME=C:\ORAWIN
      LANGUAGE=American_America.US7ASCII
      NLS_LANG=ENGLISH
      WIN_LOCAL_SESSIONS=1
      TCP_VENDOR=LANMAN
      TCP_SERVICES_FILE=C:\WINDOWS\SERVICES

    Note that the ORACLE_HOME variable is set twice, once to point to the
    version 6 <oraclehome> directory and once to point to C:\ORAWIN.

9.  If it is not already running, start Windows. Insert the ODBC Setup disk 
    in drive A, choose Run from the Windows Program Manager (or File Manager)
    File menu, and then type "a:\setup.exe" in the Command Line box. For 
    information about using the ODBC Setup program, see the online Help.

10. Run the ODBC Control Panel option and add a data source for your ORACLE
    server. For information about using the ODBC Control Panel option, see
    the online Help.

You should now be able to run the ODBC ORACLE driver. You should also be 
able to run ORACLE version 6 and version 7 tools and applications written for 
Windows. All of these can run over SQL*Net for Windows DLLs.

NOTE:  Due to differences in memory use, this configuration may not allow you 
to run ORACLE MS-DOS-only tools or applications.


If ORACLE Server is not installed on your system
------------------------------------------------

To set up the ODBC ORACLE driver and the SQL*Net for Windows DLLs if you do not
have any versions of ORACLE Server on your system:

1.  Make sure that you have the correct versions of ORACLE products, including 
    at least one SQL*Net protocol.

    Product                                  Version
    --------------------------------         -----------
    ORACLE Installer                         3.0.8.3.7
    Required Support Files                   7.0.12.1.0
    SQL*Net Named Pipes for Windows          1.1.1.3
    SQL*Net SPX for Windows                  1.1.1.5
    SQL*Net TCP/IP for Windows               1.1.7.6


2.  Install the network software connecting your client workstation to the
    server and check that a connection can be made. For example, for the 
    TCP/IP protocol, type "ping <servername>". This connection must work 
    before you install the SQL*Net for Windows DLLs.

3.  Run the ORACLE Installer program. When asked for your ORACLE installation
    directory, use the suggested default directory C:\ORAWIN.

4.  Run the ORACLE Installer in the ORACLE group in the Program Manager:

    a) Install the files from the Required Support Files disk.

    b) Install the SQL*Net protocol you will be using. For more information,
       see the ORACLE documentation.

5.  Add the following line to your AUTOEXEC.BAT file:

      SET CONFIG_FILES=C:\WINDOWS\ORACLE.INI

    NOTE: If you are using MS-DOS 6.0, add the following line to the end 
    of your AUTOEXEC.BAT file:

      SET CONFIG=

    ORACLE Server first checks the CONFIG environment variable for the path of
    the ORACLE configuration file. If the CONFIG variable is not set, ORACLE
    Server checks the CONFIG_FILES variable. Because MS-DOS 6.0 can use the 
    CONFIG environment variable during system startup, you must clear this 
    variable before leaving your AUTOEXEC.BAT file. Otherwise, ORACLE Server 
    will use its value as the path of the ORACLE configuration file.

6.  Make sure your PATH variable includes the C:\ORAWIN\BIN directory. To do
    this, add the following line to your AUTOEXEC.BAT file:

      SET PATH=%PATH%;C:\ORAWIN\BIN

7.  So that the ODBC ORACLE driver can use ORACLE version 7 error messages, 
    copy the version 7 error messages to the directory where the ODBC
    ORACLE driver searches for error messages:

      COPY C:\ORAWIN\RDBMS70\*.MSB C:\ORAWIN\DBS

8.  Search for and delete all copies of ORA6WIN.DLL from your system. A new
    (backwards compatible) version of ORA6WIN.DLL will be installed with the
    ODBC ORACLE driver.

9.  If it is not already running, start Windows. Insert the ODBC Setup disk
    in drive A, choose Run from the Windows Program Manager (or File Manager)
    File menu, and then type "a:\setup.exe" in the Command Line box. For 
    information about using the ODBC setup program, see the online Help.

10. Run the ODBC Control Panel option and add a data source for your ORACLE
    server. For information about using the ODBC Control Panel option, see
    the online Help.

You should now be able to run the ODBC ORACLE driver.


ORACLE Error Messages
---------------------
The following section explains what to do when you encounter various error
messages from ORACLE Server through the ODBC ORACLE driver.


ORA-xxxxx Message not found; product = RDBMS; facility = ORA; language = NULL
-----------------------------------------------------------------------------

The ODBC ORACLE driver searches for error messages in the subdirectory that
normally contains the ORACLE version 6 error messages. If you receive this
error, it means that the ODBC ORACLE driver cannot find the error messages.
To fix this:

1.  Check that the CONFIG_FILES variable is set in your AUTOEXEC.BAT file and
    that it points to your ORACLE configuration file (ORACLE.INI). If you are
    using MS-DOS 6.0, check that the CONFIG environment variable is either not 
    set or is cleared in the last line of your AUTOEXEC.BAT file.

2.  Check that the ORACLE_HOME variable is set correctly in your
    C:\WINDOWS\ORACLE.INI file.

    If ORACLE Server version 6 was already installed on your system,
    ORACLE_HOME should be set twice. The first time, it should be set to your
    version 6 <oraclehome> directory, usually C:\ORACLE6. The second time, in
    the [Oracle] section of the file, it should be set to C:\ORAWIN.

    If ORACLE Server was not installed on your system, ORACLE_HOME should be
    set to C:\ORAWIN.

3.  If you did not have any ORACLE software on your workstation, make sure 
    that you copied all the .MSB files from C:\ORAWIN\RDBMS70 to C:\ORAWIN\DBS.

The ODBC ORACLE driver should now be able to print the ORACLE Server error
message, enabling you to fix the problem that generated the error.


ORA-03121  No interface driver connected -- function not performed
------------------------------------------------------------------

The ODBC ORACLE driver cannot find ORA6WIN.DLL or one of the SQL*Net 
components. Check the following:

1.  Without running the ODBC ORACLE driver, make sure the network connection 
    is valid. For example, type "ping <servername>" for a TCP/IP connection.

2.  Search for and delete old versions of ORA6WIN.DLL. The correct version of
    the ORA6WIN.DLL was installed by the ODBC ORACLE driver in the SYSTEM
    subdirectory of your Windows directory.

3.  Check that the PATH variable contains the BIN subdirectory of the
    <oraclehome> directory (usually C:\ORACLE6\BIN or C:\ORAWIN\BIN).

4.  Check that the CONFIG_FILES variable is set in your AUTOEXEC.BAT file and
    that it points to your ORACLE configuration file (ORACLE.INI). If you are
    using MS-DOS 6.0, check that the CONFIG environment variable is either not 
    set or is cleared in the last line of your AUTOEXEC.BAT file.

5.  Check that SQLTCP.DLL (for TCP/IP), SQLSPX.DLL (for Novell NetWare 
    IPX/SPX), or SQLNMP.DLL (for Named Pipes) is in the ORACLE BIN directory 
    specified in the PATH variable. (If not, SQL*Net was not installed 
    correctly.)

6.  Check that ORA7WIN.DLL and COREWIN.DLL are in the ORACLE BIN directory
    specified in the PATH variable. (If not, SQL*Net was not installed
    correctly.)


ORA-06120  NETTCP: network driver not loaded
--------------------------------------------

This error can occur when ORA6WIN.DLL is loaded but cannot find another
SQL*Net component, such as SQLTCP.DLL.

1.  Check that the directories containing the SQL*Net components are in your
    PATH variable.

2.  Check that the ORACLE_HOME variable is set correctly in your
    C:\WINDOWS\ORACLE.INI file.

    If ORACLE Server version 6 was already installed on your system,
    ORACLE_HOME should be set twice. The first time, it should be set to your
    version 6 <oraclehome> directory, usually C:\ORACLE6. The second time, in
    the [Oracle] section of the file, it should be set to C:\ORAWIN.

    If ORACLE Server was not installed on your system, ORACLE_HOME should be
    set to C:\ORAWIN.

3.  Search for and delete old versions of ORA6WIN.DLL. The correct version of
    the ORA6WIN.DLL was installed by the ODBC ORACLE driver in the SYSTEM
    subdirectory of your Windows directory.

4.  Check that you have followed all the instructions for the SQL*Net driver
    you are using. For example, for the SQL*Net for TCP/IP driver, make sure
    that all the TSRs, such as NMTSR and SOCKTSR, are loaded. (If not,
    SQL*Net was not installed correctly.)


ODBC Error Messages
-------------------
The following section explains what to do when you encounter various ODBC
error messages.


IM003	Driver specified by data source could not be loaded
-----------------------------------------------------------

The ODBC Driver Manager is attempting to load the ODBC ORACLE driver
(SQORA.DLL). SQORA.DLL loads ORA6WIN.DLL to connect to the ORACLE server.
You can receive this message if it cannot find ORA6WIN.DLL or finds the wrong
version of ORA6WIN.DLL.

1.  Search for and delete old versions of ORA6WIN.DLL. The correct version of
    the ORA6WIN.DLL was installed by the ODBC ORACLE driver in the SYSTEM
    subdirectory of your Windows directory.

2.  Make sure that ORA6WIN.DLL was installed when the ODBC ORACLE driver was
    installed.
