Heterogeneous version of oracle Client in a lan

Hallo
I am a completely new by of Oracle dba.
I work in a company where there is a Lan with 2 server and 120 clients.
The lan operative system is Windows 2003 on the servers, and xp professional on the clients.
There a program for business management in oracle environment, of course.
In a server is install Oracle server version 10g.
In pc client is install version oracle client heterogenous.
In some pc there is oracle versione 7, in other pc there is version 8 and so on.
There is the possibility of malfunctioning for this reason ?
Is there a possibility problem of work on the lan or with the program ?
Thanks in advance

To communicate with Oracle 10gR2 you need a client 8.1.7.4 at least.
Oracle7 definitely won't work, and Oracle 8.0 also won't work.
Better still you install the 10gR2 client everywhere and upgrade to 10.2.0.4, as 10gR2 is in extended support, and Oracle only supports the last patch level.

  • Error :"The provider is not compatible with the version of Oracle client"

    Hi guys!
    I'm facing this problem:
    When my .Net application tries to access the DB, I get this error message above.
    The application is into the same machine of DB and the operational system is Windows Server Enterprise 64 bits.
    I'm comparing to another machine that has the same scenario but runs in Windows Vista 64 bits. This problem doesn't happen and I can normally access the DB.
    The both database versions are 10g Release 2 (10.2) and all components from Oracle Database Components 10.2.0.2.21 are installed as the containing bellow:
    -Oracle Data Provider for .NET 1.x 10.2.0.2.20

    Hi,
    Often the error "The provider is not compatible with the version of Oracle client" is raised when the unmanaged dll OraOpsX.dll can't be found, can't be loaded, or is the wrong version. For version 10.2.0.x of ODP.NET and .NET Framework 2.x the file should be called "OraOps10w.dll" and should be found in the %ORACLE_HOME%\bin directory.
    Since the ODAC pieces are installed on the same host as the database, are they in a separate Oracle Home or the same Oracle Home as the database software? If there are multiple Oracle Home directories, which one is in the system path first?
    I would start with verifying the version of OraOps10w.dll and the system path on the server. You might also confirm that the Oracle Home directory (and everything under it) has the following permissions for Authenticated Users:
    - Read & Execute
    - List folder contents
    - Read
    Regards,
    Mark

  • The provider is not compatible with the version of Oracle client

    We are running Server 2012 64 bit with multiple homes one is 32 bit and the other 64 bit. We installed the 64 bit first then the 32 bit next in order to get our Classic ASP WebSite that is using COM+ and OLEDB to see the provider.
    C:\oracle\product\12.1.0\x86
    C:\oracle\product\12.1.0\x64
    The other Websites are ASP.Net 4.0 and are running in 64 bit application pools. They are using a DAL .Net assembly built x64 with a reference to the 64 bit ODP.Net version 4.121.1.0 in C:\oracle\product\12.1.0\X64\client_1\odp.net\bin\4.
    I also see there is another folder C:\oracle\product\12.1.0\X64\odac_1\odp.net\bin\2.x with version 2.121.2.0. We are on running Framework 4.0 but when I switch to this version it works but with the version out of the bid\4 we are receiving the following error when the 64 bit Websites call the assembly:
    The provider is not compatible with the version of Oracle client
       Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    I have not been successful in getting this to work after spending endless hours, so any help would be appreciated.

    Hi,
    Oracle Client/ODP build with certified Visual C++ Libraries so application using ODP.NET requires "runtime components of Visual C++ Libraries" to be installed.
    Oracle Database Client installation includes the Visual C++ Libraries but ODAC doesn't contain these libraries which may cause such issue.
    Please check the Note 43208.1 for the particular version of Visual C++ installs with Oracle Database Client installation(e.g. 11.2.0 Database Client installs  Visual C++ .NET 2005) and also you can refer the windows event log error massage to verify which version of Visual C++ is missing.
    thanks and regards

  • 'The provider is not compatible with the version of Oracle client' exceptio

    Hi
    I installed ODAC-11.1.0.7.10 Beta on my development system and developed a .net application which uses Oracle.DataAccess.dll to connect to Oracle10g database.
    the application is working fine, means opening connection successfully when I run it from my development system. but the same application is throwing
    'The provider is not compatible with the version of Oracle client' exception when I run it on my 10g database server system.
    what I need to do to run the application successfully on the machine where 10g server exists?
    any help is appreciated.
    thanks,
    harry

    Hi Harry,
    I am not sure why you installed 11.1.0.7.10 Beta as 11.1.0.7.20 has been released and you should not be using the beta at this time. That error message is because the dependencies being loaded by the process are the wrong version. When you deploy an ODP .NET application using 11.1.7.x, you need to make sure you deploy it to a machine where the 11.1.0.7.x dependencies are installed. My guess is if I read your poat correctly is that Oracle.DataAccess.dll version 11.1 is loaded but its finding 10.2 dependencies on the target deployment box.

  • Provider not compatible version of Oracle client after upgrade 4.112.1.2

    I had an ASP.NET 3.5 website running
    on intranet small business server as production with:
    OS Win2008 Standard 32-bit
    Oracle Database 11g107 32-bit
    Oracle DataAccess 2.111.60 32-bit
    On a development laptop,
    I upgraded the website to ASP.NET 4.0.
    The development laptop had
    OS Windows 7 32-bit
    VS 2010
    Oracle Database 11g201 32-bit
    Oracle DataAccess 4.112.12
    Application was running without errors.
    On the production server,
    I uninstalled Oracle Database 11g107,
    to include removing Oracle home and install folders,
    and in HKLM > Software > Oracle registry folder.
    I installed Oracle Database 11g201
    and installed the ODP.NET upgrade to 4.112.12.
    (except for VS components).
    In the website web.config,
    I changed the referenced assembly to:
    <assemblies>
         <add assembly="Oracle.DataAccess, Version=4.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    I changed IIS70 Application pool advanced settings to ASP.NET 4.0,
    restarting application pool and website.
    Rebooted system.
    On starting the application when it accesses the Oracle connection,
    I get the dreaded: Provider not compatible.
    Exception Details: Oracle.DataAccess.Client.OracleException: The provider is not compatible with the version of Oracle client
    Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

    It is not the VB.NET Oracle connection code,
    as it runs fine on the development laptop.
    So I look into the GAC.
    GACUTIL /l shows 2.111.60 is still in the .NET

    Is there a command I need to run to remove the old 111.6.0 Oracle client references from GAC?
    Eventhough Oracle ODP.NET installer put a policy to refer the older version to the new?

    In

    So... why would I get provider not compatible version of Oracle Client...
    there are no other versions of ODAC hanging around,

    The application works fine in development laptop.
    The application works fine on production server when I use SYSTEM.DATA.ORACLECLIENT.
    But we need to migrate away from SYSTEM.DATA.ORACLECLIENT according to Microsoft,
    and I am sure Oracle would rather have me use Oracle.DataAccess client anyway.
    ++++++
    I even tried a trick from another post to move what appears to be Oracle Instant Client components,
    oci.dll, et al, from an installation into a new home of the Oracle 11g201 Cllent 32 along with Oracle.DataAccess.dll into the website BIN folder
    and set references for Oracle.DataAccess.dll to LOCAL TRUE.

  • Provider is not compatible with this version of Oracle client

    I am trying to access Oracle(10.2) DB from a .NET 2.0 Console Application.(.exe) in a Win 2008.Web code is also on the same Win 2008 system
    The Web application works fine and connects to teh DB , but when I try to run any of the Console applications it gives the error as:
    Provider is not compatible with this version of Oracle client.
    The Oracle.Dataaccess.dll versions which are available in GAC are 1.102.2.20 and 2.102.2.20.
    and the Oracle client installed is 10.2.0.100
    The complete error message is:
    Unhandled Exception: Oracle.DataAccess.Client.OracleException The provider is not compatible with the version of Oracle client
    at Oracle.DataAccess.Client.OracleInit.Initialize()
    at Oracle.DataAccess.Client.OracleParameter..ctor(String parameterName, OracleDbType type, ParameterDirection direction)
    Can any of you help me find a reason for this error.
    Thanks in advance!!

    Hi Greg,
    I found out another reason this error was appearing.I am compiling the Console application in a 32-bit machine on 32-bit Oracle client.
    The pre-compiled DLL and EXE is then exported to a 64-bit Win 2008 machine.
    Also,The code has been compiled with ‘Any CPU’ .
    The Web Application on the same system is working because the "Enable 32-bit Applications" is set to True.
    Are there any DLLs or EXEs created when compiling in the 32-bit machine which is not compatible with the 64-bit machine?
    Please help!!
    Thanks,
    Veena

  • Another: The provider is not compatible with the version of Oracle client

    Hi everybody,
    We still have problems with the ODP dll. with our .Net development. I copied all the dlls as mentioned here: [http://splinter.com.au/blog/?p=156] and in many other posts here in the forum. The .Net development works fine on our Development PCs (WIN XP32) and on many other PCs in the company. But we still have some PCs (As well WIN XP32) that come up with the Error: The provider is not compatible with the version of Oracle client.
    Has anyone an idea???
    Thanks a lot for your help
    Best Jan

    Hi Jan,
    If there has never been any Oracle Client software installed on the machines, it seems unlikely that there would be Oracle policy files and version(s) of Oracle.DataAccess in the GAC. But, yes, the CLR will look to the GAC first for loading the Oracle.DataAccess assembly. I'm not sure what Framework or Domain setting would be involved here if there is no Oracle client installed. Are the machines configured the same as far as Regional/Language settings, etc?
    One thing you might be able to try is to create an application configuration file and enable ODP.NET trace in the file. This is an ODP.NET 11.1 new feature. However, it's possible the error will prevent the trace file from being created. You would create a file named YourApplicationName.exe.config and here is a sample of the minimum content to enable ODP.NET trace:
    {noformat}
    <?xml version="1.0" encoding="utf-8" ?>
    <configuration>
     <oracle.dataaccess.client>
       <settings>
         <add name="TraceFileName" value="c:\odpnet2.trc"/>
         <add name="TraceLevel" value="1"/>
       </settings>
     </oracle.dataaccess.client>
    </configuration>
    {noformat}
    I wish I had an easy answer for you!

  • The provider is not compatible with the version of Oracle client... again!

    Please, please, please help me!
    I get the error, "The provider is not compatible with the version of Oracle client", intermittently on my Test Server. Strangely, without restarting the server or IIS, my application suddenly decides that I don't have the right Oracle client. I don't have any such issue on my local machine even though I'm using the same Oracle 11g client from Beta 1.
    I have Oracle 11g (D:\Oracle11g\product\11.1.0) installed. I tried specifying which assembly to use in my web.config:
    <compilation debug="true" defaultLanguage="c#">
    <assemblies>
    <add assembly="Oracle.DataAccess, Version=2.111.5.10, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    </assemblies>
    </compilation>
    I'm not even trying to use a 10g client with the Providers as discussed here: "The provider is not compatible with the version of Oracle client"
    What I don't understand is why this error comes and goes?!?! Has anyone experienced anything like this?

    The server is Win 2003. The local development machine is WinXP.
    ...I was trying to wait to install Beta 2 because of the nasty bugs reported on this forum.
    I'm now seeing that ORACLE_HOME wasn't set on my server because my co-worker removed the path. Somehow it was able to find an Oracle Home on the server, but apparently, it didn't always find the same home causing this error intermittently.
    Now, my question is how can I get my application to use the 11g Client as its Oracle Home, while my co-worker can use 10g Client as his Oracle Home? To be a bit more specific, he needs to use an ODBC client to connect because his application uses Classic ASP.
    Is this possible, or are we going to have to set up separate machines?

  • 'The provider is not compatible with the version of Oracle client error' popping up randomly

    I have several asp.net pages running on an application server which generally work without issue. However I've had the Server error "The provider is not compatible with the version of Oracle client error" crop up twice seemingly randomly that affects all of my pages that interact with the DB server. A simple reboot of the application server solves the issue and the pages run again with no problems. What could be causing this problem?

    Sorry if I wasn't clear initially. Basically I've got 2 different applications in 2 different IIS folders on the webserver, each with several asp.net pages. They work fine for a period of time and then inexplicably that error gets thrown and affects all of my asp.net pages in both applications. The admin tells me that the other older applications on the same server are unaffected. A simple reboot of the server fixes the issue until the next time it happens (I can't identify any consistent point where this crash happens, the admin originally suggested that there might be something in my code causing a memory issue). I had the same applications hosted on my local machine for a time and this never happened as well as it never happening when I run them in localhost. How can I trace whether or not another part of my application is trying to load ODP.NET by itself? How can I verify the DLL search order for my application?

  • Getting "The provider is not compatible with the version of Oracle client"

    Hi,
    By reading though posts this appears to be a very common and some people have been able to solve it by putting their OracleDataAccess.dll and support files in the same folder as the exe. However, I tried putting the OracleDataAccess.dll, oci.dll, ociw32.dll, orannzsbb11.dll, and oraocci11.dll in the folder and the problem persists.
    This application works fine on my development system (Windows 7 64, VS2010 SP1) and 2 of our 3 servers (Windows 2008 R2). But on this one server it does not work! The problem first appeared when a developer installed ODT with ODAC 112030 on server. We installed a full version of the 11.2.0.1.0 Oracle Client (this matches our other servers) and removed the clients created by the ODT with ODAC 112030 install. However, I fear there is something somewhere that was not deinstalled causing the issue. Any thought on how we can track down and eliminate this problem.
    Thanks,
    Jerry

  • Oracle client 32 bit version

    Hello! I installed PHP+Apache on HP-UX IA. The one PHP extension module oci8.sl requires 32 bit version library of libclntsh.so.9.0. But on this site only 64 bit version of Oracle client 9.2.0 for HP IA64. Where I can find 32 bit version for IA?

  • Oracle Client Version requirements

    We've built a program using VS2005 and ODT 10.2.0.2. The database it is accessing is 9i. In order for the program to establish connectivity with the server, we had to load Oracle Client 10.2.0.2, with the installing user having administrative priviledges. No problem. Things work fine.
    However, users access the computer with the program installed via terminal services over their network. If a user who does not have administrative priviledges via Active Directory, a error is generated stating “The provider is not compatible with the version of Oracle client”.
    If the user is given administrative priviledges, this error does not occur. As I ponder this, I wonder if terminal services uses the priviledges assigned to the user to determine the Oracle Client to use on the host computer.
    Could this be the case, or am I missing something?

    does the computer with the program installed has multiple ORACLE_HOME (i.e home for 9i client and home for ODP.NET)? I suspect, only administrators can access ODP.NET home.
