64bit instant client talking to old database (8.1.7)

This might be a stupid question, but we have recently converted all our linux machines to running 64bit linux. The problem is, we need to access an old oracle database (running on the version 8.1.7). I installed a current 64bit version of instant client (11.1) but this one won't talk to the database - probably because it is too old.
We still have a copy of an old oracle_home installation, which does talk to the database. However, this is a 32bit software and the libraries won't link to our 64bit stuff - in particular we cannot generate a working DBD:Oracle perl module.
The question: Is there an older version of instant client or anything similar, that has 64bit libraries but still supports old 8.1 database installations? I tried to downloac 10.x versions of the instant client, but the links appear to be dead and I have no idea of this one would talk to old databases.
Any hint would be highly appreciated

This link works for me:
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxx86_64soft.html
(if that is your 64 bit Linux).
With this client you will be able to connect to an 8i database, but if you have any problems, you're on your own as Oracle has desupported 8i.
Yours,
Laurenz Albe

  • Encoding issues with Instant Client and Win-1252 database

    Hi,
    I'm connecting to a Win-1252-encoded Oracle XE database from a Ruby on Rails application via ruby-oci8.
    NLS_CHARACTERSET WE8MSWIN1252
    NLS_NCHAR_CHARACTERSET AL16UTF16
    When the database and the application reside on the same physical server, the application retrieves the correct characters from the tables. But if the database resides on a different machine, then I use Oracle Instant Client; unfortunately the characters I get back from the database are then incorrect ('e' instead of 'é', 'a' instead of 'à', etc.).
    Is there some kind of setting (or another version of the Instant Client) that I can use to fix this encoding problem?
    Thanks,
    Chris.

    Hi,
    >>then I use Oracle Instant Client
    It's possible that maybe a NLS environment variables configuration problem ... For more information, I advise you to take a look at [url http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm] NLS_LANG FAQ

  • Instant Client Installation

    Dear All
    How to install instant client ? i install database 10g in my server and using 10g client for client but i want to know how to use instant client on client machine
    Regards
    Shahzaib ismail

    I installed instant client 11.1 on windows XP. Also put sqlplus in the same directory.
    Set TNS_ADMIN environment variable = "C:\instantclient_11_1\tnsnames.ora"
    set ORACLE_HOME environment variable = "C:\instantclient_11_1"
    I put a valid tnsnames.ora in said directory too.
    Sqlplus gives error
    Message file sp1<Lang>.msb not found
    Error 6 initializing SQL*Plus
    which is absurd because this is an instant client. There is not supposed to be a home, all this is supposed to be automatic. MS Visual Studio 2008 cannot connect to it either.
    Does 11g instant client work on XP at all ?
    I have installed 10g instant client on mac os x and windows xp, no problem.
    Thanks for answering. Any help appreciated. Also, if you can think of another forum I should ask this question, would appreciate it.

    I've placed my TNSNAMES and SQLNET file in the same folder having the instant client files and I've set my TNSADMIN,LD_LIBRARY_PATH and PATH environmental variable to the folder location.
    Note:I'm able to connect to the database using SQLplus.

    These days I very seldom use ODBC for Oracle - most recently it was simply to get Enterprise Architect to "talk" to Oracle. I never used it for my client applications (unlike in the fast distant past), so what I know about ODBC is seriously outdated.
    Even so, a few comments. :-)
    Have you tried creating a user DSN, in case a system DSN somehow works different environment wise?
    The above error description sounds like the original TCP connection was successful (i.e. it is not a host unknown or not reachable error). Subsequent packets seem to fails.
    To confirm, run the listener on namesrv1.xy.zz.com with logging enabled and have a look at the listener.log - does it show a connection being accepted/handled from your PC when you use the ODBC DSN?
    Have you tried the Oracle ODBC drivers? When getting EA connected I had problems (also with Instant Client) and Microsoft ODBC driver for Oracle. Downloaded and installed the Oracle ODBC driver and it worked just fine first time around.
    PS. You should raise this topic on the Instant Client Forum instead.

  • Can someone explain what is the Database Instant Client

    Download 10.2.0.4 Database Instant Client for Apple Mac OS X on Intel x86
    What does the Database Instant Client contain?
    What functionality does it have?
    Does it include a 'lite' version of the database to run locally? Or is it only a set of tools that can connect to a remote (on another machine) database?

    It is only a client for connecting to databases. It is easier to install than the full client.
    It does not include a database. Check the following link :-

  • Oracle instant client 10.2.0.4 to connect to oracle database 9.2

    got message ORA-03134 when creating ODBC connection to database version 9.2. However, it was successful to connect to database versions 10g and up. Has anyone successfully connected to Oracle 9.2 by using the 10g instant client?
    Isn't Oracle 10g instant client supported to connect to 9i databases?
    Thanks.
    Edited by: andychow on Jul 28, 2010 4:44 PM

    I think this is nothing to do with ODBC, to clarify try to connect with sqlplus to same DB.
    However, what is your exact Oracle client version?
    Looks like there was a bug in 10g, and I think issue is fixed in patch to 10.1.0.3. Check @ 10g client vs 8i server (ORA-03134): news?

  • Oracle instant client 11g doesn`t connect to database 10g

    hi,
    i installed a oracle instant client 11g for windows xp on my pc, because i need a odbc connection.
    I don`nt know this product. I don`t find a tns.ora file, so how can i give them the right parameter for my oracle database and how can i make a odbc connection.
    Is it already the right client?
    Thanks in advance.

    Thanks
    NicoleODBC sits on top of the Oracle client. (or any other native client of a given db product).
    I don't think the ODBC drivers come with the instant client, though if you can locate a 3d party odbc driver for Oracle, that should work with the instant client.
    Oracle ODBC drivers do come with the full client, but even there don't install by default - at least not up through 10g. In that case you have to select 'custom installation' (which can be done after a basic run-time installation) and select 'windows components'.

  • Obtaining an ODBC link to an Oracle 9.2 database via Instant Client

    Hi
    Justin Cave, on one of your other forums, has been assisting but as of yet we have not suceeded. He suggested that this forum may be of help.
    We are trying to find a way of linking a Microsoft Access database to an Oracle 9.2 database but as of yet have not suceeded can you please help?
    The database server we are trying to connect to has a full installation of Oracle 9.2. We have a limited number of workstations that have a fully licensed Oracle client installation (required to use our PDM system). On these workstations we can successfully configure an ODBC connection to the Oracle database on the server and link tables in MS Access. However the majority of our PCs do not have any Oracle client installed, nor do we have any further Oracle client licenses to install with (we do have the installation media for both the server and client software).
    We have attempted to use Orcale Instant Client (and ODBC addon) believing that we do not need licenses for this, at both the latest version 11.1.0.70 and at the earliest version we could find 10.1.0.5 but neither was successful in making an ODBC connection to the Oracle 9.2 database. Is this because we are using the wrong version of the Instant Client or is it just because we cannot configure it correctly? Are we correct in believing that we do not need to purchase licenses for Instant Client?
    If we are way off the mark, what can you suggest?
    Many thanks in advance.

    Hi Laurenz,
    Firstly, thank you for your prompt response.
    Secondly, in answer to some of your questions:
    1. How did you install Instant Client? By extracting the downloaded package to a directory on the local HDD (C:) maintaining the subfolder structure.
    2. What environment variables did you set? We set TNS_ADMIN using the System Properties Dialog (Environment Variables) to be the folder where Instant Client was installed to (extracted to) i.e. C:\InstantClient_11_1. We also amended the PATH to include this folder using a command prompt and typing PATH=%PATH%;C:\InstantClient_11_1. This works but only until the next reboot when the PATH reverts to the previous value.
    3. Did you run the odbc_install script to install the ODBC driver? Yes, we extracted the ODBC add-on into the same folder and ran the ODBC_install.exe script successfully.
    4. Does the driver show up in the list of drivers on your system? Yes.
    5. Do you get any error messages? When we use v11.1.0.70 and hit the test connection button within ODBC admin, we get a noticiable delay followed by 'Unable to connect... TNS could not resolve the connect identifier'. When we use v10.1.0.5 we cannot even complete the System DSN ODBC configuration.
    Our next questions are as follows:
    1. Is the TNS_ADMIN environment variable case sensitive and should it have a \ after the folder name?
    2. How do we amend the PATH permanently, so it does not revert following reboot?
    3. What part does tnsnames.ora play in the configuration. This file currently resides deep within the folder structure on the database server. Should we be copying it to the local C: and placing it in the same folder as Instant Client?
    Once again, many thanks for your help.
    Yours,
    Kevin (and co)

  • Initial Instant Client Install

    I've downloaded the latest instant client, Version 11.2.0.3.0, unzipped it - but cannot get it to install. There is no setup/install executable or batch file. What do I run to get it installed?
    I have no /Oracle directory, or installed Oracle products on my laptop.
    I'm running Windows 7, 32 bit.
    Thanks!

If not can someone please, in a step by step process a two year old could follow, tell me what to do next?I guess I cannot comply with that request, since Oracle software is not designed to be installed by two-year-olds (and I have two of those at home, so I know what I'm talking about).
    I grant that the installation instuctions provided by Oracle are minimal, they are probably supposted to emphasize how simple it is (compared to installing any other Oracle product).
    Here they are: http://www.oracle.com/technetwork/database/features/instant-client/index-100365.html#Package%20Description
    It is really just unzipping the software and configuring the environment.
    The ODBC driver needs special installation steps (the exexutabe you started), but that is described
    in the file ODBC_IC_Readme_Win.html in the ODBC driver download.
    To connect to an Oracle database, you must understand a little of Oracle Net configuration.

  • Not able to connect VS Web Developer Express through instant client 10

    I just spent 10 hours attempting to connect Web Developer Express 2010 to an Oracle 10g database. In the end the solution was beyond simple, but with the existing threads there is a lot of talking around the problem. I’m posting this in case it might help someone else.
    Obtain the Oracle instant client software that will work for your database. You will only need the basic package.
    http://www.oracle.com/technetwork/database/features/instant-client/index-100365.html
    Extract the contents to a temp location on your hard disk
    Create a directory for the application – it could be anything, but here is what I used
    C:\instantclient
    Copy the extracted files into the directory you just created.
    Right click on my computer and choose properties
    Under advanced and environment variables you will need to add the directory you created above to the system variables PATH. You will need to create a new system variable called TNS_ADMIN and put the same c:\instantclient path in it.
    Create the file tnsnames.ora under the c:\instantclient directory and put your customized entry in it. Below is an example.
    tnsnams.ora file contents
    <Alias for this tnsnames entry> =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = <Your Oracle Server>)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = <Your database instance>)
    It’s a good idea to restart your system after this installation.
    In web developer express use the .NET Framework Data Provider for OLE DB.
    Here is the key piece of information!!
    Under server name you need to use the alias from the tnsnames.ora file entry. If you do not do this it will not pick up the SERVICE_NAME parm and will give you some goofy error like:
    ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect descriptor
    or
    ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

  • Windows 7 64 Bit machine with Instant Client and 32Bit application

    Hello everybody,
    the last days a tried to get a 32Bit application to run on a Windows 7 SP1 64 Bit machine ... unfortunately with no success. The application runs on XP Pro and Vista Pro 32 Bit machines against a 11g RDBMS for years. As a refenence we use SQLTools from sqltools.net. It has nearly the same behaviour like the application, because it is a 32 bit application too.
    First thing was to install a 64 bit environement to verify if the connection is allright.
    - Downloaded instantclient-basic-windows.x64-11.2.0.2.0.zip an instantclient-sqlplus-windows.x64-11.2.0.2.0.zip
    - Unpacked both packages into C:\oracle so that they reside in C:\oracle\instantclient_11_2
    - Made a directory C:\oracle\tnsnames with tnsnames.ora in it, because the app uses it
    - Set the environement variables TNS_ADMIN to point to C:\oracle\tnsnames and added C:\oracle\instantclient_11_2 in front of the path variable
    - Restarted the machine
    - Opened a commnd shell and startet sqlplus user/password@sid
    Everything was allright, I was able to connect to the database as expected
    Second thing was to start SQLTools, but as I feard it quitted with an error message when trying to access oci.dll of the instant client.
    So i decided to switch to a 32 bit environement as a third thing.
    - Downloaded instantclient-basiclite-nt-11.2.0.2.0.zip and instantclient-sqlplus-nt-11.2.0.2.0.zip
    - Deleted the old C:\oracle\instantclient_11_2
    - Unpacked both 32 bit packages into C:\oracle so that they reside in C:\oracle\instantclient_11_2
    - Didn't change anything in the environement, because nothing changed from the view of the system
    - Opened a commnd shell and startet sqlplus user/password@sid
    But now I wasn't able to connect and got the following error
    ORA-28547: connection to server failed, probable Oracle Net admin error
    SQLPlus was able to start now, but when trying to connect to the database I got the same error like when connecting with sqlplus.
    Does anybopdy have an idea how to manage to get a 32 bit application to run on a Windows 7 64 Bit machine?
    Thanks in advance
    My packages:
    Windows 7 64 bit SP1
    Oracle Instant Client basic lite 11.2.0.2.0
    SQLPlus 1.5 22D

    Have you tried WOW64 ? I have not used this emulator for sqlplus but it works for other 32 bit applications.

  • Oraclle 11g instant client x64 doesn't  work in windows 7 x64

    First of all I've read the software requirements in the installation guides for 11g instant client x64 and no support for Windows 7 is mentioned.. I'm not sure if this is the case any how here is the details of the problem:
    I downloaded instant client (basic) and (sqlplus) and unzipped them on drive E, afterwards I created tnsnames.ora file with the following:
    ORCL =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP) (HOST = IGGY) (PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = ORCL)
    and saved it in the instant client directory, afterwards I included the instant client directory in the user variable PATH value, and created system variable TNS_ADMIN and added the location of tnsnames.ora in the value.
    Now the problem starts when I open MS-DOS and type: sqlplus system @ORCL, It then prompts for the password and when I try to enter anything the cursor doesn't move unless I press enter and the result is that I get the following error:
    ORA-12154: TNS: COULD NOT RESOLVE THE CONNECT IDENTIFIER SPECIFIED
    Any idea what the reason of this problem is?

    Hello again,
    I was able to reproduce ORA-12154 and the error raised beacause my DUMMY-HOST was not reachable. Using the correct hostname/IP address solved the issue. Can you check if you are able to ping and to telnet your hostname (IGGY).
    Regards,
    David

  • Instant client installation unavailable in ODBC data sources

    I'm trying to install instant client to enable MS Excel to access an Oracle database. OS is Windows 7.
    After installing instant client plus the odbc package, I can't see a new entry in the odbc data sources - only the standard Microsoft sources (Excel, Access, SQL Server) show up.
    There's also an Oracle SQL developer installation on my computer. Connection to the database works fine in SQL developer - so the DB does exist and it is accessible.
    Steps conducted during instant client installation:
    - Downloaded basic lite instant client (11.2.0.3.0) for windows.x64
    - Downloaded odbc package for windows.x64
    - unpacked zip file to instantclient directory
    - executed the odbc_install.exe in the instantclient directory. I'm not sure if this install.exe does anything at all. There was no error message but also no confirmation or reaction of any kind.
    - executing the install file from the cmd window gave me a message, that the odbc drivers were already installed. So I guess odbc_install.exe was executed properly
    - setting some system variables
         1) path variable: added instantclient directory to the ones already listed in path
         2) tns_admin: new entry, pointing to instantclient directory
         3) ld_library_path: new entry, pointing to instantclient directory
    - wrote an tnsnames.ora file using the connect information also used in SQL developer
    - saved tnsnames.ora file in instantclient directory
    - rebooted computer to activate changes
    When opening the odbc data source administration, I'm only able to see Microsoft drivers for Access, Excel, SQL Server. I'd expect to get an Oracle driver option to add to the installed drivers.
    Wild & uneducated guesses about what might cause the problem:
    - IC is installed on E: drive. Maybe some component is expected to be saved on C: (low likelihood, many others would have complained by now)
    - Win 7 often asks for explicit permission to do this or that via popup windows. Maybe the odbc-component encounters such a request ans says "Ummm....???"
    Any idea, what I might try to get an oracle entry in the odbc data source list?
    Best regards
    Peter

    I'm not sure to be honest, but what I downloaded did not have a setup.exe.
    Does what you're talking about allow you to connect to Oracle databases via ODBC? If so, is it downloadble from the Oracle site?
