My suggestion would be to break this out into 2-3 different modules, each of which would be used by the scripts that need that functionality. Right now, it looks like you have two different functionalities - database connectivity and filelists. So, I would do something like: 
# In file Database.pm
package Database;

our @ISA = qw(Exporter);
our @EXPORT_OK = qw(
    DB_connect
    DB_disconnect
);

use DBI;

my %config = (
    type => 'mysql',
    name => 'SUN',
);

sub DB_connect
{
    # Allow the user to override anything they want to in %config
    %config = (%config, @_);

    my $connect_string = join(':',
        'DBI',
        $config{type},
        $config{name},
    );

    my $dbh = DBI->connect(
        $connect_string,
        $config{user},
        $config{password},
        $config{options},
    );

    unless ($dbh)
    {
        die "Cannot open connection to $connect_string with $config{us
+er} / $config{password}\n" . DBI->errstr, $/;
    }

    return $dbh;
}

sub DB_disconnect
{
    my ($dbh) = @_;

    $dbh->disconnect if UNIVERSAL::isa($dbh, 'DBI');

    return 1;
}

1;

You can do something similar with your files. Now, you have connecting to a database abstracted out into something you can reuse.
