Help says you cannot use Pessimistic Locking with ServerAutocommit. If it
obvious if you understand how IB works.
Probably the message is misleading here.
The best thing you can do is to plan your application for optimistic locking
and only use pessimistic in very special scenarios. BTW, most C/S engines
have introduced optimistic locking recently.
