Correct, and apologies, it's too easy to give
the quick and simple answer.

If you want to rebuild the whole thing, without
changing tablespaces, then:

    alter table iot_tab move overflow;

You can't move the overflow with an online move,
of course (except in Oracle 9, I expect).

If you also have LOB columns you may have to
add further details to make those move too, such as

    alter table iot_lob_tab move lob(my_lob) store as my_lob_seg;

which would rebuild the index layer, overflow layer, and
lobsegment layers.

|It seems to me that alter table <iot_table> move --> just rebuilds
the the
|branching part of the index.
|So if this is the case---> export & import or create table <iot> as
... are
|the best way to do the real job.
