I'm having a little trouble with accessing an old DBM file using DBI.

We have an old DBM file:

data.pag
data.dir
[download]

#!/usr/bin/perl -w
use strict;
use warnings;
use DBI;
use CGI;
use CGI::Carp qw(fatalsToBrowser);

# start error output
   BEGIN {
             use CGI::Carp qw(carpout);
             carpout(*STDOUT);
       }

print "Content-type:text/html\n\n";

my $db_name = 'data';
my $dbh = DBI->connect('dbi:DBM(RaiseError=1):');
my $sqlSelect = "SELECT * FROM $db_name";
my $sth = $dbh->prepare($sqlSelect) || die "Cannot prepare: " . $dbh->
+errstr();
$sth->execute() or die "Cannot execute: " . $sth->errstr();

while (my @data = $sth->fetchrow_array()) {
     print "<br>";
     for my $i (0 .. $#data) {
         print ", $data[$i]\n";
     }
}
$sth->finish;

Software error:

DBD::DBM::st execute failed: 
Execution ERROR: No write permission to sdbm file at /bla/bla/bla/DBD/
+DBM.pm line 422.
.

 at /bla/bla/bla/DBI/DBD/SqlEngine.pm line 1234.

Now, I was previously getting the error "no lck file" - so I simply created an empty data.lck file and that seemed to shut that up.

What's up?

Thanks.
