These instructions apply to install ODP.NET, Managed Driver. 1. Un-GAC and un-configure any existing assembly (i.e. Oracle.ManagedDataAccess.dll) and policy DLL (i.e. Policy.4.121.Oracle.ManagedDataAccess.dll) for the ODP.NET, Managed Driver, version 12.1.0.2 that exist in the GAC. Remove all references of Oracle.ManagedDataAccess from machine.config file, if any exists. 2. In Visual Studio 2010, 2012, 2013, or 2015 open NuGet Package Manager from an existing Visual Studio project. 3. Install the NuGet package from an OTN-downloaded local package source or from nuget.org. From Local Package Source ------------------------- A. Click on the Settings button in the lower left of the dialog box. B. Click the "+" button to add a package source. In the Source field, enter in the directory location where the NuGet package(s) were downloaded to. Click the Update button, then the Ok button. C. On the left side, under the Online root node, select the package source you just created. The ODP.NET NuGet packages will appear. From Nuget.org -------------- A. In the Search box in the upper right, search for the package with id, "Oracle.ManagedDataAccess". Verify that the package uses this unique ID to ensure it is the official Oracle Data Provider for .NET, Managed Driver download. B. Select the package you wish to install. 4. Click on the Install button to select the desired NuGet package(s) to include with the project. Accept the license agreement and Visual Studio will continue the setup. 5. Open the app/web.config file to configure the ODP.NET connection string and local naming parameters (i.e. tnsnames.ora). Below is an example of configuring the local naming parameters: After following these instructions, ODP.NET is now configured and ready to use. NOTE: ODP.NET, Managed Driver comes with two platform specific assemblies: i. Oracle.ManagedDataAccessDTC.dll (for Distributed Transaction Support) ii. Oracle.ManagedDataAccessIOP.dll (for Kerberos Support) The Oracle.ManagedDataAccessDTC.dll assembly is ONLY needed if you are using Distributed Trasactions and the .NET Framework being used is 4.5.1 or lower. If you are using .NET Framework 4.5.2 or higher, this assembly does not need to be referenced by your application. The Oracle.ManagedDataAccessIOP.dll assembly is ONLY needed if you are using Kerberos5 based external authentication. Kerberos5 users will need to download MIT Kerberos for Windows version 4.0.1 from http://web.mit.edu/kerberos/dist/ to utilize ODP.NET, Managed Driver's support of Kerberos5. These asssemblies are located under packages\Oracle.ManagedDataAccess.\bin\x64 and packages\Oracle.ManagedDataAccess.\bin\x86 depending on the platform. If these assemblies are required by your application, your Visual Studio project requires additional changes. Use the following steps for your application to use the 64-bit version of Oracle.ManagedDataAccessDTC.dll: 1. Right click on the Visual Studio project. 2. Select Add -> New Folder 3. Name the folder x64. 4. Right click on the newly created x64 folder 5. Select Add -> Existing Item 6. Browse to packages\Oracle.ManagedDataAccess.\bin\x64 under your project solution directory. 7. Choose Oracle.ManagedDataAccessDTC.dll 8. Click the 'Add' button 9. Left click the newly added Oracle.ManagedDataAccessDTC.dll in the x64 folder 10. In the properties window, set 'Copy To Output Directory' to 'Copy Always'. For x86 targeted applications, name the folder x86 and add assemblies from the packages\Oracle.ManagedDataAccess.\bin\x86 folder. Use the same steps for adding Oracle.ManagedDataAccessIOP.dll. To make your application platform independent even if it depends on Oracle.ManagedDataAccessDTC.dll and/or Oracle.ManagedDataAccessIOP.dll, create both x64 and x86 folders with the necessary assemblies added to them. Installation Changes ==================== The following app/web.config entries are added by including the "Official Oracle ODP.NET, Managed Driver" NuGet package to your application: 1) Configuration Section Handler The following entry is added to the app/web.config to enable applications to add an section for ODP.NET, Managed Driver-specific configuration:
Note: If your application is a web application and the above entry was added to a web.config and the same config section handler for "oracle.manageddataaccess.client" also exists in machine.config but the "Version" attribute values are different, an error message of "There is a duplicate 'oracle.manageddataaccess.client' section defined." may be observed at runtime. If so, the config section handler entry in the machine.config for "oracle.manageddataaccess.client" has to be removed from the machine.config for the web application to not encounter this error. But given that there may be other applications on the machine that depended on this entry in the machine.config, this config section handler entry may need to be moved to all of the application's .NET config file on that machine that depend on it. 2) DbProviderFactories The following entry is added for applications that use DbProviderFactories and DbProviderFactory classes. Also, any DbProviderFactories entry for "Oracle.ManagedDataAccess.Client" in the machine.config will be ignored with the following entry: 3) Dependent Assembly The following entry is created to ignore policy DLLs for Oracle.ManagedDataAccess.dll and always use the Oracle.ManagedDataAccess.dll version that is specified by the newVersion attribute in the element. The newVersion attribute corresponds to the Oracle.ManagedDataAccess.dll version which came with the NuGet package associated with the application. 4) Data Sources The following entry is added to provide a template on how a data source can be configured in the app/web.config. Simply rename "MyDataSource" to an alias of your liking and modify the PROTOCOL, HOST, PORT, SERVICE_NAME as required and un-comment the element. Once that is done, the alias can be used as the "data source" attribute in your connection string when connecting to an Oracle Database through ODP.NET, Managed Driver. Documentation Corrections and Additions ======================================= This section contains information that corrects or adds to existing ODP.NET documentation, which can be found here: http://www.oracle.com/technetwork/topics/dotnet/tech-info/index.html 1. ODP.NET Entity Framework Database First and Model First applications using Entity Framework 6 requires .NET Framework 4.5 or higher. 2. All Oracle database clients support interrupting database query execution, such as through an ODP.NET command timeout. The database server can be interrupted via either TCP/IP urgent data or normal TCP/IP data, called out of band (OOB) or in band data, respectively. Windows-based database servers only support in band breaks, whereas all other (predominantly UNIX-based) database servers can support OOB or in band breaks. ODP.NET, Managed Driver uses OOB breaks by default with database servers that support it. For certain network topologies, the routers or firewalls involved in the route to the database may have been configured to drop urgent data or in band the data. If the routers or firewalls can not be changed to handle urgent data appropriately, then the ODP.NET, Managed Driver can be configured to utilize in band breaks by setting the .NET configuration parameter disable_oob to "on". The default value for disable_oob is "off". disable_oob can be set in the of the .NET config file for . As with all ODP.NET, Managed Driver settings, disable_oob can be set in either the .NET config or sqlnet.ora files, whereas it can only be set for ODP.NET, Unmanaged Driver in the sqlnet.ora file. ODP.NET, Managed Driver Tips, Limitations, and Known Issues =========================================================== This section contains information that is specific to ODP.NET, Managed Driver. 1. OracleConnection object's OpenWithNewPassword() method invocation will result in an ORA-1017 error with 11.2.0.3.0 and earlier versions of the database. [Bug 12876992] 2. Stored functions/procedures in a PDB cannot be added to a .NET Entity Framework model. [Bug 17344899]
