Mercurial Monks,

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

We have an old DBM file:

data.pag data.dir
I simply want to see what's in it. Thought the DBI would be a good way, so:
#!/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;
But what I get is
Software error: DBD::DBM::st execute failed: Execution ERROR: No write permission to sdbm file at /bla/bla/bla/DBD/ line 422. . at /bla/bla/bla/DBI/DBD/ line 1234. [for Statement "SELECT * FROM pmb_passwords_dbm"] at lin +e 26.
For the record - both the files are chmod'd 755.

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?
