    You could check if you have just installed provider but not the client.

    On the application server, locate the Oracle Client installation and open the ODP.NET folder

    Open the BIN folder and find the version of .NET you are using ... 2.0/3.5 or 4.0 and open that folder

    Copy that version of OracleDataAccess.dll into the /BIN folder of your application,

    make a LOCAL reference to it

    and recompile.
