我正在尝试使用Oracle.ManagedDataAccess 6.121.1.0提供程序实现代码第一次迁移，但是根本没有成功。

当我收到ORA代码时，我假设连接已成功打开。但是迁移是失败的，因为可能，提供程序表现为sql Server，而不是Oracle。我认为这是托盘使用“dbo”作为默认模式。

这是我的web.config设置：

type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,EntityFramework,Version=6.0.0.0,Culture=neutral,PublicKeyToken=b77a5c561934e089"

requirePermission="false" />

type="OracleInternal.Common.ODPMSectionHandler,Oracle.ManagedDataAccess,Version=4.121.1.0,PublicKeyToken=89b483f429c47342" />

type="Oracle.ManagedDataAccess.EntityFramework.EFOracleProviderServices,Oracle.ManagedDataAccess.EntityFramework,Version=6.121.1.0,PublicKeyToken=89b483f429c47342" />

invariant="Oracle.ManagedDataAccess.Client"

description="Oracle Data Provider for .NET,Managed Driver"

type="Oracle.ManagedDataAccess.Client.OracleClientFactory,PublicKeyToken=89b483f429c47342" />

providerName="Oracle.ManagedDataAccess.Client"

connectionString="Data Source=OracleServer:1521/BRSYSDS;User ID=USER;Password=PASSWORD;" />

这里Stacktrace：
