yes thanks both

saw these responses today and the issue is we are a 24x7 shop so can't downtime anything - I guess restore a copy using RMAN to a dev box and then do the tablespace thing from there is it starts to take a LONG time.

thanks for the tips - i was just worried i was being really dumb when it came to the imp
