Hello! I need some help with it, tried many variants but no results.

Today we've deployed a new virtual server, I've made a copy of my ASP.Net app on it.

First of all I installed "Oracle_ODAC121024_x64".

Then opened my Visual Studio 2013 project and attached all DLL's from "instantclient-basic-windows.x64-12.1.0.2.0" into main folder at Solution Explorer.

After that I added a reference to Oracle.DataAccess from the GAC64 directory:

I also changed the compiler option to x86:

There is not any specific changes in my web.config:

<?xml version="1.0" encoding="utf-8"?>

<configuration>

<configSections>

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

</configSections>

<system.web>

<compilation debug="true" targetFramework="4.5" />

<httpRuntime targetFramework="4.5" />

</system.web>

<connectionStrings>

<remove name="LocalSqlServer" />

<remove name="OracleDBServer" />

<add name="LocalSqlServer" connectionString="Data Source=SSP01T; database=Zaliffka; Integrated Security=True;" providerName="System.Data.SqlClient" />

<add name="OracleDBServer" connectionString="SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.44.444.44)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=STEEL)));uid = USR; pwd = PaSS;" />

</connectionStrings>

</configuration>

No changes in any other configuration files too.

When I trying to run debug IE shows me an error:

Server Error in '/' Application.
