You'd do better, probably, on the dbi-users@perl.org mailing list.
If the driver is implemented properly, activity on a separate database
handle ($dbh2, say) definitely won't (shouldn't) affect the insert ID on
the current one ($dbh1). If I was asked, I'd the say the same of
statement handles on the same $dbh; $st1 and $st2 should be able to have
separate 'last inserted ID' values (and DBD::Informix implements that),
but I'm not sure what the DBI spec (perldoc DBI) has to say about it.
