Hi! > I believe Oracle is enforcing this to guarantee consistency of the > database. I realise you are probably using the APPEND hint for performance > reasons but is it really necessary? Yes, when you're doing an insert in append mode, Oracle takes an exclusive lock on the table and inserts rows above high-water-mark, without raising the highwatermark itself. HWM is risen to appropriate position when you commit, so when you rollback, the HWM is just left where it was before. I don't see a reason why the same session shouldn't be able to do several consecutive direct load inserts on a table, but I might have missed something, or Oracle just hasn't implemented this improvement yet...
