Instant Client on Windows

I know how to setup instant client on unix but I need to setup this on windows so that the dev can access the database using odbc, I just want to install the basic + odbc libraries and I have downloaded them too. But can anyone tell me what env varables do I need to configure on windows in order to get it working.
Mainly I want to configure one tnsnames.ora which I can refer while creating the DSN to use odbc.
Client: Win XP
Server: Linux + Oracle 10gR2

I agree, but this is for the QA group and they generally test the app and access the DB using app only but now for some certain modules they want to check the data in the database but they dont know how to write SQL so they decided to use microsoft sql writer (I never used it :) ) and for that they want to setup odbc and for that they need client, so they are not going to use sqlplus and that why I just wanna install instant client on their desktops.

  • Any simple program available for testing instant client for Windows

    Any simple program available for testing installation of instant client for Windows.
    Thankx in advance

    Having a program means you need a dev environment to compile, link and then test it with your instant client env.
    I would suggest you download sqlplus ZIP and connect to a DB server.

  • Unable to install 64-bit Oracle ODBC Instant Client on Windows 2008 R2 machine.

    I am trying to upgrade the Oracle ODBC driver from the 32-bit version currently installed (ODBC Instant Client Release 10.1.0.5.0, April 2006) to a newer 64-bit version but have not been successful.  I have had success at uninstalling and reinstalling the existing 32-bit version package (release 10.1.0.5.0) however when I've tried to install the 64-bit ODBC Instant Client (Release 12.1, December 2012), I run the odbc_install.exe application inside the package.  it appears to run without issue/compliant, but then I do not see the 64-bit Oracle ODBC driver anywhere, either if I go via the traditional Administrator Tools --> ODBC Data Sources or if I go to the c:\windows\syswow64\odbcad32.exe route.  Further investigation into the ReadMe file (ODBC_IC_Readme_Win.html) reveals that you need the 3 DLLs oci.dll, oraociei11.dll and orannzsbb11.dll which the package does not come with. Where could I obtain the correct version of these DLLs or else where can I get an installation package which already contains them?
    Any help with this is greatly appreciated.  Thank you

  • Instant Client on Windows is released!

    Instant Client has been released on Windows! See
    http://otn.oracle.com/tech/oci/instantclient/instantclient.html
    for details.
    There is also a separate forum for Instant Client:
    Instant Client

    Talking about registry settings...
    Where is ODBC? Is there a separate driver install?
    Description mentions "Basic: All files required to run OCI, OCCI, and JDBC-OCI applications (and ODBC on Windows)". But the two (or is it three) driver files are missing form the archive and moreover you would need the .reg info to configure odbc datasources.

  • Instant client on windows 2000, path problems

    I have successfully installed the client and all work fine. But from time to time for no apparent reason php script gives an error
    "Warning oci_connect (): OCIEnvNlsCreate () failed. There is something wrong with your system - please check that PATH includes the directory with Oracle Instant Client libraries."
    I checked the environment variables, they are correct.
    If you restart Apache, everything starts to work fine. What may be the problem?
    (sorry for my English, it's not my native language)

  • Instant Client 10.2.0.1 for Windows 64-bit x86-64?

    Does anyone know when Instant Client for Windows on x86-64 might be released?

    We also badly need that build - thanks in advance ;)
    One of our customers uses a Citrix Farm based on Windows 2003 Server x64 (EM64T), on which our Client has to run (using the ODBC-driver of the Instant Client) and that customer don't want to install the Oracle Client.

  • Oracle 11g Instant Client availability on Windows

    We have just installed and tested new features on Oracle 11g Linux and Windows.
    We had a problem in the deployment phase, we installed the Oracle Instant Client in Windows connected to Oracle 11g Server with Linux.
    The systems seems is not working correctly, when will be the instant client 11g for Windows available?
    We have a urgent need to know it.
    Thanks a lot.

    I don't think the instant client is available yet for windows nor linux.
    As for the 11g client beta on windows, you can get it via ODAC.

    Make sure that you have only one Oracle Client on the client machine.
    Delete/uninstall all others. Best uninstall all Oracle Software on that machine and reinstall one client.
    Before you try to connect from a PHP script, try to connect with sqlplus. If that works, proceed.
    The PHP you use must compiled and linked against the Oracle client version you use, else it won't work.
    Now try again. If you still get the same errors, post the error messages and relevant parts of the PHP script.
    Be aware that this forum is for Instant Client, so there might be better forums for PHP questions.

  • Instant Client with SQLServer2005 Linked Server

    I have successfully installed Instant Client 11.2.0.1.0 on my Windows Server2008. I am able to create an ODBC data source selecting the driver "Oracle in instantclient_11_2". I have also been able to link tables from Access to Oracle. I can logon to Oracle through SQLPlus and execute a query against the Oracle database. I am unsure how to set a Linked Server object in SqlServer 2005. When I use "Microsoft OLE DB Provider for ODBC Drivers" and supply the Product - DBName and Data Source - ODBC data source previously created here is the error I receive:
    TITLE: Microsoft SQL Server Management Studio
    "The linked server has been created but failed a connection test. Do you want to keep the linked server?"
    ADDITIONAL INFORMATION:
    An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
    Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "DB1".
    OLE DB provider "MSDASQL" for linked server "DB1" returned message "Specified driver could not be loaded due to system error 1114 (Oracle in instantclient_11_2).". (Microsoft SQL Server, Error: 7303)
    Thanks!

    Although the 10.1.0.3 instant client for windows doesn't appear to be "officially out", if I try to download
    http://download.oracle.com/otn/nt/instantclient/instantclient-basic-win32-10.1.0.3.zip and similar files, the files do exist.
    Unfortunately this version still can't connect to my corporate Oracle database:
    Oracle8i Enterprise Edition Release 8.1.6.0.0, 64 bit - Production
    With the Partitioning option
    JServer Release 8.1.6.0.0 - Production
    Oh well, back to a full client install of Oracle 9i.
    Perhaps the official release when its documented on the Instant Client download page will work.

  • Instant Client 10.1.0.5 and ORA-12640 with External Authentication

    I am using v10.1.0.5 of Instant Client on Windows 32bit. I have hit bug 5114330 (ANO: ORA-12640 authentication adapter initialization fails if Operating System User does not have admin rights). This was fixed in patch 12 of 10.1.0.5. I copied the updated files from patch 28 that related to the instant client files and I am still hitting the same problem. How do I patch my instant client install to overcome this bug? Using v10.2 of instant client is not an option as it is not compatible with our application.
    Kind regards,
    Steve

    I guess that if you know what you are doing, that approach should work fine; the "standard procedures" are there to guide people who have little experience and to provide a cookbook for how to do it.
    I am not sure about version 10.1, but in Instant Client 10.2 everything except for the Instant Client shared library (in 10.1 that is oraociei10.dll) is the same as the regular client. The Instant Client shared library contains messages and similar, so probably has no influence on a code bug as you experience it.
    What I would do in your case is to install the regular client on a test machine, apply the patch there and see if the problem is fixed there.
    If not, you have a better case for Oracle support, because they understand the regular client much better.
    If it works there, replace the Instant Client shared libraries with the files from the regular client and see if it works.
    In the case that the error persists, I guess there's no way around a Service Request, because nobody except for Oracle can look into the code.

  • Instant client with Oracle 8i server
