Reducing Database Fragmentation

Oracle9i database admin guide says, a fragmented database should be reorganized to make space. The solution is to make a full db export, delete the db, recreate the db, and a full db import. Is there another easier option?

oracle 9.2.0.1.0

----->
Yes, there is an easier option. Use locally managed tablespaces. Do you have a fragmentation problem? Are you currently using locally managed or dictionary managed tablespaces?

----->
Yes, we are using locally managed tablespaces, does it mean I don't have to worry about fragmentation?

----->
It means you don't have to worry about it as much. Are you using uniform extent sizes or system managed extent sizes? If you are using uniform extent sizes, then you won't have any fragmentation issues. All extent sizes are the same. If you are using system managed extent sizes then fragmentation is greatly reduced, to the point that you shouln't have to be concerned with it. Have you identified that you have a fragmentation issue?

----->
No we havent, that's another problem, I don't know how to identify if we have... I will look it up.
