Solution #622 - How to use the Oracle Data Provider for .NET (ODP.NET) provider with COM-based apps

This works as of Dovetail SDK 3.3

1. Add an environment variable named TNS_ADMIN that points to where your tnsnames.ora file is located.
   This is typically done in the system environment variables within the windows system properties control panel.
   Or, if running a command line app, you can test it by simply defining that variable for that command line session like so:
   DOS> set TNS_ADMIN=C:\Apps\oracle64\client\product\12.1.0\client_1\network\admin

2. Add the Oracle.ManagedDataAccess.dll to the GAC (Global Assembly Cache)
   The Oracle.ManagedDataAccess.dll is shipped with the Dovetail SDK.
   To add it to the GAC, use the Global Assembly Cache tool (Gacutil.exe)
   gacutil -i Oracle.ManagedDataAccess.dll

3. In your fc.env file, set the db_type to ODPNet, like so:
   db_type=ODPNet

4. Test your app.

DEBUG level logging of the application and SDK are useful if a problem arises.
