Well first of all, upgrade Perl and those modules, if at all possible. That DBI is NINE YEARS OLD! As for the warning, what I generally do is disconnect in an END block right after I connect, like so: my $dbh = DBI->connect('dbi:Oracle:...'); END { $dbh->disconnect if $dbh } I also recommend against having AutoCommit set to 0, as that means you have a transaction open all the time. You should just use transactions when you have reason to use them, that is for database writes. Best, David
