difference between source based commit? and target based
commit? which is better with respect to performance?

Answer Posted / siva

If you set the source based commit, say 1000, it executes
commit after immediate of 1000 records read, irrespective
of how many rows passed to target (may be 600 since 400
dropped).

Similarly, if you set target based commit, say 1000, it
executes commit after immediate of 1000 records inserted,
irrespective of records read from source (may be 1500, rest
of 500 dropped)..

I think you got it..
