Hi.

I've two Oracle Databases: Prod1 and Test1 (both on 11G)

PROD1:
NLS_CHARACTERSET WE8ISO8859P15

Test1:
NLS_CHARACTERSET WE8MSWIN1252

On both databases i've a user called MYUSER with the
password "€" (simple euro-sign). I've set the password with Oracle SQLDeveloper like this
alter user MYUSER identified by "€";

ODAC-Version is 9.6.20 for RAD Studio 10 Seattle.

I'm trying to connect to...
Prod1 using ODAC: failed with ORA-01017
Test1 using ODAC: succeeded
Prod1 using SQLDeveloper: succeeded
Test1 using SQLDeveloper: succeded

TOraSession:
.Options.Charset = ''
.Options.Direct = true
.Options.UnicodeEnvironment = false
.Options.UseUnicode = false

Here is what i've tried so far:

1)
Changed TOraSession to:
.Options.UnicodeEnvironment = true
.Options.UseUnicode = true
=> failed with ORA-01017 on Prod1

2)
Changed TOraSession to:
.Options.Charset = 'WE8MSWIN1252'
=> failed with ORA-01017 on Prod1

3)
Changed TOraSession to:
.Options.Charset = 'WE8ISO8859P15'
=> failed with ORA-01017 on Prod1

4)
Changed Password on both Databases to a character
which is defined in 7-BIT Ascii e. g. "~" like this
alter user MYUSER identified by "~";
=> login with ODAC succeeded on Prod1 and Test1

It seems to be a problem regarding wrong character-sets on client and server.
What do i need to do to connect to Prod1? Specifying the character-set in the torasession seems not to work.

Thanks.

Hi.

I still can't connect to the oracle-db with NLS_CHARACTERSET=WE8ISO8859P15 when i use the password "€" (decimal 164 in WE8ISO8859P15) (i got an EOraError with ORA-01017 on every login).
A connection to the oracle-db with NLS_CHARACTERSET=WE8MSWIN1252 with the same password "€" (decimal 128 in WE8MSWIN1252) works.

The problem seems to occur when the password has a character which isn't defined in the 7-Bit-Range of the ascii-table. Hence no character which is greater than dec(127) like € or § are allowed.

The password has been set with Oracle SQL Developer using this statement:

Code: Select all

alter user MYUSER identified by "€";

Code: Select all

select ascii('€') from dual;
-- gives me "164" on the WE8ISO8859P15 DB
-- gives me "128" on the WE8MSWIN1252 DB

The login credentials seems to be transmitted in the wrong characterset.

Code: Select all

show parameter SEC_CASE_SENSITIVE_LOGON;
-- gives me TRUE on the WE8ISO8859P15 DB
-- gives me TRUE on the WE8MSWIN1252 DB

Here is a sample to reproduce the issue (Delphi 10 Seattle with Devart ODAC 9.6.20 Professional and Oracle 11.2.0.4):

Code: Select all

unit oratest;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
  Vcl.Controls, Vcl.Forms, Vcl.Dialogs, DBAccess, OdacVcl, OraCall, Data.DB, Ora,
  Vcl.StdCtrls;

type
  TForm1 = class(TForm)
    OraSession1: TOraSession;
    ConnectDialog1: TConnectDialog;
    Button1: TButton;
    Label1: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure OraSession1AfterConnect(Sender: TObject);
    procedure OraSession1Error(Sender: TObject; E: EDAError; var Fail: Boolean);
  private

  public

  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  OraSession1.Connect;
end;

procedure TForm1.OraSession1AfterConnect(Sender: TObject);
begin
  if OraSession1.Connected then
    Label1.Caption := 'connected';
end;

procedure TForm1.OraSession1Error(Sender: TObject; E: EDAError;
  var Fail: Boolean);
begin
  Label1.Caption := 'connection failed';
end;

end.

Code: Select all

object Form1: TForm1
  Left = 0
  Top = 0
  Caption = 'Form1'
  ClientHeight = 152
  ClientWidth = 578
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'Tahoma'
  Font.Style = []
  OldCreateOrder = False
  PixelsPerInch = 96
  TextHeight = 13
  object Label1: TLabel
    Left = 208
    Top = 64
    Width = 31
    Height = 13
    Caption = 'Label1'
  end
  object Button1: TButton
    Left = 208
    Top = 8
    Width = 177
    Height = 25
    Caption = 'Connect to DB'
    TabOrder = 0
    OnClick = Button1Click
  end
  object OraSession1: TOraSession
    Options.Direct = True
    ConnectDialog = ConnectDialog1
    AfterConnect = OraSession1AfterConnect
    OnError = OraSession1Error
    Left = 32
    Top = 32
  end
  object ConnectDialog1: TConnectDialog
    Caption = 'Connect'
    ConnectButton = 'Connect'
    CancelButton = 'Cancel'
    Server.Caption = 'Server'
    Server.Visible = True
    Server.Order = 1
    UserName.Caption = 'User Name'
    UserName.Visible = True
    UserName.Order = 2
    Password.Caption = 'Password'
    Password.Visible = True
    Password.Order = 3
    Home.Caption = 'Home Name'
    Home.Visible = False
    Home.Order = 0
    Direct.Caption = 'Direct'
    Direct.Visible = False
    Direct.Order = 6
    Schema.Caption = 'Schema'
    Schema.Visible = False
    Schema.Order = 4
    Role.Caption = 'Connect Mode'
    Role.Visible = False
    Role.Order = 5
    Left = 136
    Top = 32
  end
end

Is this a bug? Or am i doing something wrong?
Any ideas? Do you need some further information?

Thank you very much.

We have investigated the ODAC behavior when using Oracle 11.2.0.4 with NLS_CHARACTERSET WE8ISO8859P15 and found no issues: when using a '€' symbol as a user password, connection to database is established successfully. A small console application proves that:

Code: Select all

program EuroApp;

{$APPTYPE CONSOLE}

{$R *.res}

uses
  System.SysUtils, DB, Ora;

var
  OraSession: TOraSession;
begin
  OraSession := TOraSession.Create(nil);
  try
    OraSession.Options.Direct := True;
    OraSession.Server := '< Oracle Server with WE8ISO8859P15 >:1521:sn=< Oracle Serviсe Name >';
    OraSession.Username := '< Oracle user name >';
    OraSession.Password := '€';
    OraSession.Connect;
    if OraSession.Connected then
      WriteLn('Connected !');
    ReadLn;
    OraSession.Disconnect;
  finally
    OraSession.Free;
  end;
end.

Try to modify the application, so that the database connection error reproduces.

I've changed the following lines of your sample:

Code: Select all

...
OraSession.Server := 'localhost:1522:testdb';
OraSession.Username := 'myuser';
OraSession.Password := '€';
...

Unfortunately i still can't connect.

I' ve created another database:

Code: Select all

-- "select * from nls_database_parameters":
NLS_LANGUAGE	AMERICAN

NLS_TIMESTAMP_TZ_FORMAT	
NLS_DUAL_CURRENCY	
NLS_COMP	BINARY
NLS_LENGTH_SEMANTICS	BYTE
NLS_NCHAR_CONV_EXCP	FALSE

As you can see it has the NLS_CHARACTERSET of WE8MSWIN1252.
I've tried to connect to this db and got the same (ORA-01017) error.
So it seems that it has nothing to do with the nls_characterset (sorry for that).

Code: Select all

The database i can connect to runs on 11.2.0.3. I'm pretty sure there are more
differences between those databases than only the nls_characterset.

Which db-parameters influences the direct-mode connection?
Can you provide me a debug.exe which i can use to provide you more information
about my database connection. Maybe we can tackle the problem this way.

Thanks!

Using the provided application, we connected successfully to databases with WE8ISO8859P15 and WE8MSWIN1252 charsets. Therefore it is quite difficult for us to determine which of the parameters of your database instance don't allow to use the euro symbol as a password. Try contacting your DB Oracle administrator to solve the issue.
