    ODBC Error

      Hello,

      I'm getting an error when trying to set up an ODBC data source. I just installed the ODBC driver 9.2.0.54. When I test the connection, I first get an error that says:

      The procedure entry point lxhlcmod could not be located in the dynamic link library oranls9.dll.

      Then I get the same error again. The next message box says:

      Unable to connect
      SQLState=IM004
      [Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed

      I would be most appreciative of any light someone could shed on this!

      Thank you, and happy new year,

      Owen Gibbins

          What version of the Oracle client do you have installed?

            I think you did not configure your Data source (ODBC) using the the ODBC Data source Administartor Panel. Did you add the Oracle ODBC driver using the File DNS tab. If well confogured, it will work.

                Enterprise Manager is version 9.2.0.1.0

                Is this the same as the client version? I couldn't find anywhere else that gave a version number.

                Thanks,

                  I think you did not configure your Data source (ODBC)
                  using the the ODBC Data source Administartor Panel.
                  I didn't know there was any other way of doing it. So yes, I did configure the data source using the ODBC Data Source Administrator panel.
                  Did you add the Oracle ODBC driver using the File DNS
                  tab. If well confogured, it will work.
                  No, I did it as a System DSN. It used to work... just recently I have started getting these error messages. I have installed Application Server and a newer version of JDeveloper since the last time the ODBC worked.
                  I tried it just now as a File DSN but that didn't work either.

                    I assume that you installed the application server into a different Oracle Home than the Oracle client. If you go to the Oracle Home Administrator, try selecting the home of your Oracle client. Let me know if that fixes things.

                      Have you tested you JDeveloper connection to your database to see if the connection is ok without the ODBC. If it does then reconfig your ODBC.

                        Well, that helped a lot, but now there is another problem. I don't get the bizarre error any more, but I can't login as a regular user. I tried the following logins: (ap is the user I want to use for the login)

                        service name=(blank) user=ap -> doesn't work
                        service name=orcl user=ap -> doesn't work
                        service name=(blank) user=system -> works
                        service name=orcl user=system -> doesn't work

                        I can make do with logging in as system as this is just a development machine. But if anyone can shed some light on this, that would be great!

                        Thanks for everyone's suggestions and comments so far.

                          I can log in as ap perfectly well from SQL Plus and through JDeveloper.

                            have you created that user you want to use and grant the necessary privileges to the user.

                              Are you logging in to a database on the local machine or on a remote machine? What error message do you get when your logins fail?

                                The user is created and has privileges, which is how I can use it in SQL Plus, etc.
                                Are you logging in to a database on the local machine
                                or on a remote machine? What error message do you
                                get when your logins fail?
                                Everything is local.
                                When I use the service name ORCL with user as either system or ap, I get a ORA-12154: TNS:could not resolve service name.
                                When I use a blank service name and user ap, I get ORA-01017: invalud username/password; logon denied

                                I don't know why ORCL would not be recognized. It works (and seems to be required) when I logon in SQL Plus. This is the entry in tnsnames.ora: (I renamed every other instance of tnsnames.ora that I found on the system.)

                                ORCL =
                                (DESCRIPTION =
                                (ADDRESS_LIST =
                                (ADDRESS = (PROTOCOL = TCP)(HOST = grapevin-pnanmy)(PORT = 1521))
                                )
                                (CONNECT_DATA =
                                (SERVER = DEDICATED)
                                (SERVICE_NAME = ORCL.WORKGROUP)
                                )
                                )


                                Thank you,

                                  Can you type "tnsping ORCL" at the command-line and see if that works?
