Facing issue in connecting oracle with entity frameowrk

I am using Oracle 11g and Entity Framework 6 versions.
I am facing the following error:
"An error occurred while getting provider information from the
database. This can be caused by Entity Framework using an incorrect
connection string. Check the inner exceptions for details and ensure
that the connection string is correct."
My App.Config is as follows:

My Db Context:
class DatabaseContext : DbContext
{
public DatabaseContext() : base("OracleDbContext")
{
}
public DbSet<User> Users { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
//Configure domain classes using modelBuilder here
modelBuilder.Entity<User>().ToTable("HRMS_OLAS_TREE");
modelBuilder.Entity<User>().Property(user => user.ID).HasColumnName("EMP_ID").HasColumnType("VARCHAR");
modelBuilder.Entity<User>().Property(user => user.NAME).HasColumnName("EMP_NAME").HasColumnType("VARCHAR");
base.OnModelCreating(modelBuilder);
}
}
internal class User
{
public long ID { get; set; }
public string NAME { get; set; }
}
Please let me now what mistake i am doing.

I have changed the connection string to the following and it started working:
<add name="OracleDbContext" providerName="Oracle.ManagedDataAccess.Client"
connectionString=" Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname)(PORT=yourportnumber))(CONNECT_DATA=(SERVICE_NAME=""servicename))); User Id=xxx;Password=xxxx;"/>
we can find these details in tnsnames.ora file.
In Db Context add the following code:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.HasDefaultSchema("yourschemaName");
modelBuilder.Configurations.Add(new EmployeeMapper());
}

Inserting a new record updates LocalDB but not SQL server DB

I'm following MVC-Movies tutorial here , and I'm trying to update the records on SQL Server
and NOT on LocalDB .
When I add a new record in my program , for example :
The DB in SQL Server is not updated , only the LocalDB is .
Here is Web.config :

Where did I go wrong ?
Name of my DB in sql server is : MoviesDB
Thanks
EDIT:
Class Movie and MovieDBContext :
using System;
using System.Data.Entity;
using System.ComponentModel.DataAnnotations;
namespace MvcMovie.Models
{
public class Movie
{
public int ID { get; set; }
public string Title { get; set; }
[Display(Name = "Release Date")]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime ReleaseDate { get; set; }
public string Genre { get; set; }
public decimal Price { get; set; }
}
public class MovieDBContext : DbContext
{
public DbSet<Movie> Movies { get; set; }
}
}
EDIT 2 :
I changed the connection string to
<add name="MovieDBContext"
connectionString="Data Source=localhost;
AttachDbFilename=|DataDirectory|\Movies.mdf;
Initial Catalog=MoviesDB;
Integrated Security=True"
providerName="System.Data.SqlClient" />
But then I get this :
Server Error in '/' Application.
Invalid value for key 'attachdbfilename'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Neither one of your connection strings there are referencing MoviesDB.
One is referring to aspnet-MvcMovie-20140418101450.mdf and the other Movies.mdf.
Your context will use the connection string that matches it's name, unless you override that setting. So you should modify the MovieDBContext connection string to point to your SQL instance instead of the LocalDB
Edit
I assume that this is similar to the connection string you actually want, but you should refer to the official Microsoft Reference for other examples.
<add name="MovieDBContext" providerName="System.Data.SqlClient"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=MoviesDB;
Integrated Security=True"/>

Change to :
<add name="MovieDBContext"
connectionString="Data Source=localhost;
AttachDbFilename=|DataDirectory|\MoviesDB.mdf;
Initial Catalog=MoviesDB;
Integrated Security=True"
providerName="System.Data.SqlClient" />

EF 6 with System.Data.SQlite SaveChanges() not working?

So I just started using System.Data.Sqlite with entity framework 6 (downloaded the latest System.Data.Sqlite from Nuget, version 1.0.91.0)
After some configuration and code, I found out that I can read from the database but somehow write is not working.
Here's my code:
using (var context = new InternalDbContext())
{
var demo = context.DemoEntities.Where(d => d.ID == 1).FirstOrDefault();
demo.Name = "TestTest";
context.DemoEntities.Add(new Demo { Name = "Test" });
context.SaveChanges();
}
Basically after SaveChanges, nothing was updated in the DB. However I can read fro the DB with the data I manually populated via SQlite admin tool.
Here's my DB schema:
Table name :Demo
Field: ID - Integer Primary Key AutoIncrement
Field: Name - VARCHAR(256)
Here's my classes
public class InternalDbContext : DbContext
{
public DbSet<Demo> DemoEntities { get; set; }
public InternalDbContext()
{
// Turn off the Migrations, (NOT a code first Db)
Database.SetInitializer<InternalDbContext>(null);
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
// Database does not pluralize table names
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}
[Table("Demo")]
public class Demo
{
public long ID { get; set; }
public string Name { get; set; }
}

If anyone could point me to the right direction, that'd be fantastic, thanks so much

Your ./bin/Debug/ folder should contain a copy of your testdb.sqlite DB. That should have the changes.

I'm using Entity Framework 5 , MySqlConector 6.7.4.0, Visual Studio 2012. Hope you guys can help me with this!

I found the answer with the post that user2453734 pointed EF5 Getting this error message: Model compatibility cannot be checked because the database does not contain model metadata and made a changes in the SetInitializer in Program.cs and I changed
this:
Database.SetInitializer(new DropCreateDatabaseIfModelChanges<MySqlContext>());
into this:
Database.SetInitializer<MySqlContext>(new DropCreateDatabaseIfModelChanges<MySqlContext>());
now it works!

Logged in users get logged out after some time

I made a new MVC3 application and it's hosted on WinHost's basic plan.
The gist of the problem is, the app pool memory limits are reached and every session InProc is erased, meaning my users are logged out.
As per their documentation, I see this:
http://support.winhost.com/KB/a626/how-to-enable-aspnet-sql-server-session-on-your-web.aspx
Here is the contents of my web.config after following the steps outlined above:

Here lies the problem:
My users are still getting logged of after some time. I thought using SQL for the session would prevent this issue.
Here is the relevant bit of code on how I'm loggin my users in:
[HttpPost]
public ActionResult Login(LogOnModel model)
{
using (EfAccountRepository accountRepository = new EfAccountRepository())
{
if (accountRepository.ValidateCredentials(model.Email, model.Password))
{
FormsAuthentication.SetAuthCookie(model.Email, true);
return RedirectToAction("Index", "Home");
}
}
ModelState.AddModelError("", "Your email or password is incorrect.");
return View(model);
}
And here is some code I use to see if the user is logged in:
public static MvcHtmlString AdminDashboardLink()
{
if (SecurityHelpers.UserIsPartOfCompany(HttpContext.Current))
{
string html = "<li><a href='/Admin'>ADMIN DASHBOARD</a></li>";
return new MvcHtmlString(html);
}
else
{
return new MvcHtmlString("");
}
}
public static bool UserIsPartOfCompany(HttpContext context)
{
if (!context.Request.IsAuthenticated)
return false;
using (EfAccountRepository accountRepository = new EfAccountRepository())
{
var loggedInUser = accountRepository.FindByEmail(context.User.Identity.Name);
string[] userRoles = accountRepository.GetRolesForUser(loggedInUser.AccountId);
return userRoles.Contains("Editor") || userRoles.Contains("Finance") || userRoles.Contains("Administrator");
}
}
Any suggestions? Maybe my web.config is botched and this is causing issues. Maybe I also needed to remove something after I added in the session information?

It is caused some times because the garbage collector cleans the machine key assigned to your application and assigns a new key that causes the looged in users to log out. Solution is to generate a machineKey for your application and place it in the web.config under system.web like
<system.web>
<machineKey validationKey="###YOUR KEY HERE ###"
decryptionKey="## decrypt key here ##"
validation="SHA1" decryption="AES" />
...
...

Forms auth is not session related, at all. It has nothing to do with session state. Everything required is stored in the forms auth cookie.
Your timeout above is set to 2880, so 48 hours i.e. two days so I would expect timeouts to happen.
