DBD::Oracle version 1.06

This particular cursor is a statemtent handle cursor of the form:

$sql = "select 'x', 'y' from dual";
$sth=$dbh->prepare(qq{$sql});
$sth->execute;
($x, $y) = $sth->fetchrow_array;
$sth->finish;

open_cursors parameter is 50
there does not seem to be a max_open_cursors param defined

Thanks for any and all comments!
