Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am a newbie so please forgive my question that might seem simplistic. I have created a CGI script that connects to an Oracle database. When I run the script from the c prompt everything is a success. I create the database and plot it. However when I try to submit the html form that calls the script, it fails. If I comment out the section in which the script talks to the database, everything works. Here is part of the code: 
 
my $q = new CGI;
my($surname, $givenName);

$ENV{REMOTE_USER} = $q->param('Login_Name');
my $room = $q->param('Room');

my $sth;
my $table = SQL->new();

my $dbh= DBI->connect("dbi:Oracle:", "scott", "tiger") or die $DBI::er
+rstr;

if (!($dbh->selectrow_array("select * from user_tables where table_nam
+e = '$table->{name}'"))){
    $sth= $dbh->prepare($table->create) or die $dbh->errstr;
    $sth->execute or die $sth->errstr;
}

$sth = $dbh->prepare(q/INSERT INTO SignIn(cn, time, cdate, room) VALUE
+S (?,?,?,?)/) or die $dbh->errstr;
$sth->execute($ENV{REMOTE_USER}, $foo, $foo, $room);


print <<ENDOFHTML
$ENV{REMOTE_USER}, $time, $date, $room
Content-type:text/html\n\n
<html>
<body>
<SCRIPT language="JavaScript">
alert("$givenName $surname you have signed in successfully on $fullDat
+e. Thank you and enjoy Computers 101.")
</SCRIPT>                                       
</body>
</html>

ENDOFHTML

Here is the module that I created 
package SQL;

sub new{
    my $self = {};
    $self->{name}='SIGNIN';
    bless $self;
    return $self;
}

sub create{
    my $self = shift;
    $self->{create} = "create table SignIn (cn varchar2(64), time varc
+har2(10), cdate varchar2(20), room varchar2(20))";
    return $self->{create};
} 

sub index{
    my $self = shift;
    $self->{index} = "create index CNIndex on self->{name}(cn)";
    return $self->{index};
}

1;

Re: connect to Oracle through CGI

    Hi , The Oracle Environment Parameters are not set from with in the CGI when called from HTML , I guess and hence get those Oracle env parameters in a file and require "./oraenv.pl"; in your CGI . This may help recognize the Oracle env. Also see the error message in web server log. Regards , Padmaraj K.Shankar (Pad)

    It helps if you post the error message too. You can probably find it in the error_log file of your webserver.

      I'm using Apache so its the usual error of:

      The server encountered an internal error or misconfiguration and was unable to complete your request

      I think it might have something to do with the permission of the oracle directory.... Please help if you can

        The *actual* message from the error_log is what everyone is looking for.
