no using update strategy without primary keys update is not
possible. try and read teh session log file once. it will
display a msg updates are not supported without primary
keys.
update override in the target is to update the function in
the update strategy t/tion and it updates only on non-
primary key columns like dname, loc but not on deptno.

Other than this option like "Target update Override "
you can drag that target Warehouse desiner ,and mark those
columns which are no keys as a key for time being ,on whihc
you are trying to update. even though those columns are
not keys attributes or key columns at database level,for
time being those will be treated as key elements, hense you
can apply or use update strategy .
else generally informatica will through error like
" No key specification error"

Answer / leo gilbert
By using "Update override" option in the target. Say the
key of your table is ID,NAME. But your mapping is passing
only ID to the target then you can have an update override
query in the target to update the target only based on
ID.
