Check this:
select * from dba_segments where segment_name = 'ANAGTITOLI_BP';
particularly check the value for "extents" field in above query. May be the table had too many updates and deletes and so the high water mark might have got set too high.

I saw that the value is 11...but I don't know what I have to do with it.
Anyway, I have many updates on the table...have you got any advice for this?

without execution plan / statspack or generated statistics how can you say that the indexes are used??.
ANd you are not posting the sql involved.
If you can't post the necessary information, no forum can help.
Best of luck.
