'The recommended provider ('Oracle.DataAccess.Client') is not installed. You can continue with your current provider, however it has been deprecated and may not work properly.' I've installed Oracle Database Access Components (ODAC), specifically '64-bit ODAC 12c Release 4 (12.1.0.2.4) for Windows x64' from this link. 'The recommended provider ('Oracle.DataAccess.Client') is not installed. You can continue with your current provider, however it has been deprecated and may not work properly.' I click on 'Learn more' hyperlink which led me to this document page.

Our application is built and packaged with oracle 11g Oracle.DataAccess.dll and in the same box we have installed 12.2 Oracle Client (No other oracle client is installed). The Oracle server is running on 12.2 version. Now, when we are installing our product, it is trying to communicate to Oracle Server via the client. But the Oracle.DataAccess.dll of our product (which is basically 11g version) is not able to communicate to 12.2 Oracle Client. Is there a way we can communicate successfully? We don't want to package the 12.2 dll with our installer and release it immediately.

Feb 12, 2019 - Hi, I have installed multiple Oracle drivers on multiple machines that all use PowerBi x64. Tableau, sqlplus and oracle SQL connect perfect.

Please suggest if there is any tweak which can make it compatible. Thanks, Arindam. No, version of Oracle Client and version of Oracle.DataAccess.dll have to match. You may face problems even if the minor versions are different, e.g.

Oracle.dataaccess.client not found

Client Version 12.1.0.2.x vs. Oracle.DataAccess.dll version 12.1.0.1.x.

But it should be no problem, provided the ODP.NET (i.e. Oracle.DataAccess.dll) is installed with Oracle Client. The GAC should include Policies like Policy.4.112.Oracle.DataAccess.config -> It does not matter whether your application was build with ODP.NET version 11.2, the policy should redirect it to installed version 12.2 automatically. Otherwise go to one of these pages • • and download the matching XCopy version. Extract correct Oracle.DataAccess.dll file from ZIP and provide it together with your application.

Installing Oracle Data Provider for.NET Oracle Data Provider for.NET can be installed through XCopy or Oracle Universal Installer. • XCopy Administrators use XCopy to deploy Oracle Providers for ASP.NET to large numbers of computers for production deployments. The XCopy has a smaller installation size and fine grain control during installation and configuration than Oracle Universal Installer. • Oracle Universal Installer (OUI) Developers and administrators use Oracle Universal Installer for automated ODP.NET installations.

It includes documentation and code samples that are not part of the XCopy. Note: This section describes installation using the Oracle Universal Installer. For installation and configuration using the XCopy install, refer to the README.TXT file that is part of the XCopy installation. Additionally, Oracle Data Provider for.NET Dynamic Help is registered with Visual Studio, providing context-sensitive online help that is seamlessly integrated with Visual Studio Dynamic Help. With Dynamic Help, the user can access ODP.NET documentation within the Visual Studio IDE by placing the cursor on an ODP.NET keyword and pressing the F1 function key. Oracle Data Provider for.NET creates an entry in the machine.config file of the computer on which it is installed, for applications using ADO.NET 2.0 and OracleClientFactory class.

This enables the DbProviderFactories class to recognize ODP.NET. Windows Registry Upon installation, ODP.NET creates entries for configuration and tracing within the Windows Registry. Configuration and tracing registry values apply across all ODP.NET applications running in that Oracle client installation.

Individual ODP.NET applications can override some of these values by configuring them within the ODP.NET application itself (for example, FetchSize). The ODP.NET registry values are located under: HKLM Software Oracle ODP.NET version. There is one key for.NET Framework 1. X and one key for.NET Framework 2.0 and higher.

Configuration File Support and Search Order for Unmanaged DLLs For customers who have numerous applications on a computer that depends on a single version of ODP.NET, the Windows Registry settings for a given version of ODP.NET may not necessarily be applicable for all applications that use that version of ODP.NET. To provide more granular control, ODP.NET Configuration File Support allows developers to specify ODP.NET configuration settings in an application config, web.config, or a machine.config file. If a computer does not require granular control beyond configuration settings at the ODP.NET version level, there is no need to specify ODP.NET configuration settings through configuration files.The following is an example of a web.config file for.NET Framework 1. X: The following is an example of a web.config file for.NET Framework 2.0: Through the use of the DllPath configuration parameter, each application can specify the ORACLE_BASE ORACLE_HOME bin location that the dependent unmanaged Oracle Client binaries are loaded from. However, the ORACLE_BASE ORACLE_HOME must have the same ODP.NET version installed as the version that the application uses. Otherwise, a version mismatch exception is thrown.

The Oracle.DataAccess.dll assembly is installed as follows:

  • NET Framework 1.x

    ORACLE_BASEORACLE_HOMEodp.netbin1.x directory

  • NET Framework 2.0

    ORACLE_BASEORACLE_HOMEodp.netbin2.x directory

Documentation and the readme.txt file are installed in the ORACLE_BASEORACLE_HOMEODP.NETdoc directory.

Samples are provided in the ORACLE_BASEORACLE_HOMEODP.NETSamples directory.

Windows Registry

Configuration and tracing registry values apply across all ODP.NET applications running in that Oracle client installation. Individual ODP.NET applications can override some of these values by configuring them within the ODP.NET application itself (for example, FetchSize). The ODP.NET registry values are located under: HKLMSoftwareOracleODP.NETversion.

There is one key for .NET Framework 1.x and one key for .NET Framework 2.0 and higher.

Search Order for Unmanaged DLLs

Oracle Dataaccess X64

The DllPath registry value is used to indicate the directory that contains dependent unmanaged DLLs.

The Oracle.DataAccess.dll searches for dependent unmanaged DLLs (such as Oracle Client) in the following order:

  1. Directory of the application/executable.

  2. Directory specified by:

    HKEY_LOCAL_ MACHINESoftwareOracleODP.NETversionDllPath

  3. Directories specified by the PATH environment variable.

Upon installation of ODP.NET, the DllPath registry value of type REG_SZ is set to the ORACLE_BASEORACLE_HOMEbin directory where the corresponding dependent DLLs are installed.

ODP.NET and Dependent Unmanaged DLL Mismatch

To enforce the usage of Oracle.DataAccess.dll assembly with the correct version of its unmanaged DLLs, an exception is raised if Oracle.DataAccess.dll notices it has loaded a mismatched version of a dependent unmanaged DLL.
