you can compress tables, and associated indexes as well. Remember that in some versions of 92xx, you can't do direct exports, they throw ora-600. also you cannot alter columns using ddl when compressed, so you need to be able to un-compress if table needs to be altered.

Otherwise it may be a good thing, as always all expressed opinions are invalid without you doing tests to satisfy your needs in your environment.
