RAD Studio XE4 Update1 + Mobile
SecureBridge 6.0.1
ODAC 9.1.3
Oracle Database 11g Release 11.2.0.1.0

I have problems when try to connect to Oracle via ScSSHClient on iOS IPAD;

If the SSHServer is up all work properly.
If the SSHServer, for some reasons, is down, application hangs and exceptions aren't raised.

Here is my code:

////////////////////////////////////////////////////////////////////////////////
procedure TdmMain.OraSessionBeforeConnect(Sender: TObject);
////////////////////////////////////////////////////////////////////////////////
var
MyConnectParams: TStringList;

begin
// Connection to Oracle via SSH tunnel
MyConnectParams := TStringList.Create;
try
MyConnectParams.Delimiter := ':';
MyConnectParams.DelimitedText := OraSession.Server;
ScFileStorage.Path := GetHomePath + PathDelim + 'Documents' + PathDelim;
ScSSHClient.HostName := MyConnectParams[ 0 ];
ScSSHChannel.DestHost := '127.0.0.1';
ScSSHChannel.SourcePort := 1520;
ScSSHChannel.DestPort := StrToInt( MyConnectParams[ 1 ] );
OraSession.Server := '127.0.0.1:1520:' + MyConnectParams[ 2 ];
// Connessione SSH
try
ScSSHClient.Connect;
except
// 001
ErrorBox( '001: Impossibile collegarsi al server!' );
OraSession.Close;
end;
// Port forwarding
try
ScSSHChannel.Connect;
except
// 002
ErrorBox( '002: Impossibile collegarsi al server!' );
OraSession.Close;
end;
finally
MyConnectParams.Free;
end;
end;

On ScSSHClient.Connect, Delphi raise this exception:
'Socket error on connecting. Error code = 61($3$D) Connection refused';

If I continue execution, the program stalls and nothing happens.

How can I solve this problem?

Thanks.

Are you able to simulate the problem?
Thanks.
Best regards.

Thank you for the information. We have reproduced and investigated this problem. It seems, that the problem is arisen because of the specificity of the compiler under iOSDevice.
As a workaround, try compiling your project in the Release mode (not Debug) and check if this problem still exists.
We will avoid this behaviour in the next SecureBridge build.

When the new version will be available?
Thanks.
Best regards.

New build of SecureBridge version 6.1.2 with fixed bug with hanging application on iOS is available for download now.
