Ok LQ.

 

I have edited Config.pm:

 

  # database settings                                    #
    # ---------------------------------------------------- #
    # DatabaseHost
    # (The database host.)
    $Self->{'DatabaseHost'} = 'localhost';
    # Database
    # (The database name.)
    $Self->{'Database'} = 'otrs';
    # DatabaseUser
    # (The database user.)
    $Self->{'DatabaseUser'} = 'otrs';
    # DatabasePw
    # (The password of database user. You also can use bin/CryptPassword.pl
    # for crypted passwords.)
    $Self->{'DatabasePw'} = 'hot';
    # DatabaseDSN

I think that this tells me that the name of my database is really OTRS as I thought. Right?

 

However, unhappily, I still could not find it into SQL Querry Analizer.

 

What a hell!
