Which parameterts are you referring to? I wrote a brief article on storage parameters for DW environments here ... http://databasejournal.com/features/...le.php/3304791 ... which might help.

You certainly shouldn't be specifying initial, next and pctincrease, if you are referring to those, whether in a DW or an OLTP environment, but this applied back in v7, as well as in 8i, 9i, 10g.
