    Issue in connecting Oracle 11g  to the .Net Framework 4

    959748
      Hi All,

      I am trying to install a 3rd party application,which connects to oracle database in my windows 2008 R2 machine.
      When i test the database connection i am getting the below error

      "*For DBEngineType: 'Oracle' the selected provider invariant name is: 'Oracle.DataAccess.Client'*

      *Test connection failed: Unable to find the requested .Net Framework Data Provider. It may not be installed*."

      OracleDataAces is present in the C:\Windows\assembly path.I added the following lines in the machine.config also under Framework as well as Framework64 folder

      " <DbProviderFactories>
      <add name="Oracle Data Provider for .NET"
      invariant="Oracle.DataAccess.Client"
      description="Oracle Data Provider for .NET"
      type="Oracle.DataAccess.Client.OracleClientFactory,
      Oracle.DataAccess,
      Version=2.112.1.2,
      Culture=neutral,
      PublicKeyToken=89b483f429c47342" />
      </DbProviderFactories>
      "
      still Iam getting the same error

      .net Framework version is: 4.0
      Oracle DataAccess Version is : 2.112.1.2

      Do I have to set the path of the Oracle DataAccess or do i have to get the upgraded version of this?
      Plz let me know what to do?

      Thanks,
      Mouli
