in thread Problem storing value in persistent hash with MLDBM

It's really not an issue of the storage mechanism (dbm vs. RDBMS), just a simple problem with Perl's TIE mechanism. In your case, I would change it so that you always write to $sessions->{$session_id} when you modify anything in the session. For example: 
my $aref = $sessions->{$session_id};
$aref->{timestamp} = time;
$sessions->{$session_id} = $aref;

    That's basically what I have done. I have insert_key() method, which updates $session object, but also updates the tied %{$sessions} variable. You can only see and refer to $session object from the main screen, the update of tied hash structure %{$sessions} happens when you call $session->insert_key().
