Hi, all.

I'm using OraConnection from System.Data.OracleClient. I'm readed MSDN 
documentation about how to make connection string to specify connection 
parameters, but how the hell i can connect with this as privileged user SYS? 
Usually when i connect as SYS to Oracle i need to write something:

> sqlplus "sys@my_oracle_db as sysdba"

I'm tried to pass:

"Server=mica;Password=xxxxx;User ID=sys;Persist Security Info=true"

Typical answer is: "System.Data.OracleClient.OracleException: ORA-28009: 
connection to sys should be as sysdba or sysoper".

What i need to pass to OracleConnection.Create to connect as sysdba?

P.S. Yes i really need to connect as sysdba and i know what i'm want to do.

P.P.S. No i do not want to use BDP, it is too buggy and has too limited 
functionality for me.

P.P.P.S. This is code which supposed to be work with connection...

unit cDataCore;
interface
uses
 SysUtils, Classes, System.Data, System.Data.OracleClient;

type

TDataCore = class
strict private
 FConnection: OracleConnection;
strict protected
 procedure SetConnection(const Value: OracleConnection);
public
 constructor Create(const ConnectionString:String);
 property Connection:OracleConnection read FConnection write SetConnection;
end;

implementation

constructor TDataCore.Create(const ConnectionString:String);
begin
 inherited Create;
 Connection:=OracleConnection.Create(ConnectionString);
 Connection.Open;
end;

procedure TDataCore.SetConnection(const Value: OracleConnection);
begin
 if Value=FConnection then Exit;
 if FConnection<>NIL then FConnection.Free;
 FConnection := Value;
end;
