It's harder than that anyway.
a) Extent management in 8.1 goes into

        a couple of x$ if you use locally  managed
        tablespaces.

b)    If you stick with system-managed tablespaces
        the things that reports dba_segments and
        dba_extents is such nasty view that they take
        ages to run.  You don't want to query them
        regularly.
