I have some large tablespaces about 20 GB with just two tables about 10GB each. how can I defrag this tablespace ? export/importing these tables takes a long time ( > 24hrs ) which is unpracticle in our environment. Any ideas on how I can do this in less time.
thanks for any help.

Oracle Version?
In Most cases, you do not need to worry about fragmentation with a proper tablespace design.
10gb tables are kinda 'small'.
You can do online table redifinition.
if you can afford offline , this is much simple.
sql> alter table table_name move tablespace_name;
Please search the forum for FRAGMENTATION.
You might find lots of interesting details.
Edit:
And Andrew was faster
