Oracle uses row-level locking which means that unless you update every row of
the table the whole table should not be locked. The commit statement will
release any row locks put in place by the sql statements submitted during the
same session as the one which issued the commit. Oracle even handles deadlocks
for you (it rolls back both sessions). I have never been in a situation where
I have had to worry about locks on table or rows (except trying to resolve a
deadlock between two bits of code).
