Tablespace defragmentation

Hi netters!

I would like to defragment all my tablespaces.

0- About the SYSTEM tablespace, I've posted an

   article monday, but I have received no help    since now...

1- temporary tablespace

   The temp tablespace doesn't contains data, but I    have actually a Free Space Fragmentation Index (FSFI)    with value 23.8094802, so I need to defragment it.    How to do? Simply drop tablespace temp, create    tablespace temp? What about the users who have    this tablespace defined as temporary tablespace?

2- index tablespaces

   At the moment no problem (FSFI = 100, wow!).    But in case I have to do it, what to do?    I can try to guess: drop indexes, drop tablespace inx01,    create tablespace inx01, create index using inx01.    Right? Others solutions?

3- data tablespaces

   Also have to do it. FSFI = 23.1302211    Export compress=Y + import?
   Have to drop/create all the tables before to import?

Very grateful for any help!
Stefano
