How to set Initial Catalog in connection string for Oracle?

Question

I'm trying to setup IdentityServer3 to work with Oracle database. I've got working MSSQL solution and I need Oracle variation too.

During initialization I get following error. It looks like provider reaches timeout (30-45 s) and then throws the exception.

The supplied SqlConnection does not specify an initial catalog or AttachDBFileName.

Error occurs in System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create. To be more specific in

IdentityServer3.EntityFramework.DbModelBuilderExtensions
.RegisterScopeChildTablesForDelete[TScope](DbContext ctx) in
IdentityServer3.EntityFramework\Source\Core.EntityFramework\Extensions
\DbModelBuilderExtensions.cs

Here is my web.config connection string:

<add name="ApplicationDbContext" 
     providerName="Oracle.ManagedDataAccess.Client" 
     connectionString="User Id=xxxxxxx;
                       Password=xxxxxxx;
                       Data Source=OracleDataSource" />

and here is the rest of web.config (any how related to Oracle)

 <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
      <provider invariantName="Oracle.ManagedDataAccess.Client" type="Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices, Oracle.ManagedDataAccess.EntityFramework, Version=6.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    </providers>
  </entityFramework>

  <system.data>
    <DbProviderFactories>
      <remove invariant="Oracle.ManagedDataAccess.Client" />
      <add name="ODP.NET, Managed Driver" invariant="Oracle.ManagedDataAccess.Client" description="Oracle Data Provider for .NET, Managed Driver" type="Oracle.ManagedDataAccess.Client.OracleClientFactory, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
    </DbProviderFactories>
  </system.data>

  <oracle.manageddataaccess.client>
    <version number="*">
      <dataSources>
        <dataSource alias="OracleDataSource" descriptor="(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XE))) " />
      </dataSources>
    </version>
  </oracle.manageddataaccess.client>

How can I add Initial Catalog to my connection string for Oracle?

Versions

IdentityServer3: v 2.5
EntityFramework: 6.1.3
Oracle ManagedDataAccess EntityFramework: 12.1.4

Update 1:

I've tried simply adding Initial Catalog to my conn string, but it doesn't seem to work (Oracle XE, C++ ADO):

<add name="ApplicationDbContext" 
     providerName="Oracle.ManagedDataAccess.Client" 
     connectionString="User Id=xxxxxxx;
                       Password=xxxxxxx;
                       Data Source=OracleDataSource;
                       Initial catalog=XE" />

Maybe XE is not the name of my database? Should I use schema instead?

The problem was defaultConnectionFactory

<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />

After replacing with OracleConnectionFactory things moved on

<defaultConnectionFactory type="Oracle.ManagedDataAccess.EntityFramework.OracleConnectionFactory, Oracle.ManagedDataAccess.EntityFramework" />
