If you can use the online keyword then DML can happen
concurrently, if not, then not. You don't give a reason for your
desire to spend resources doing a rebuild, for a table with few
writes my presumption would be that a rebuild wouldn't help with
any problem you might have (you don't describe one) on the other
hand since I prefer to do maintenance out of hours or during low
activity then it might do your overtime hours some good. There's
a rather important football match Sunday - that might make a
good time.

i have a big table ( 10 GB ) which has an index on a number
field. Index is almost same size as the table and I want to
rebuild the index
the database is very active and the table is also very
active read about 100K times in 20 minutes and few writes as
well. I want to know during the index rebuild process, does
oracle allow writing to the table ( insert into that table) ?
Please let me know, i am kind of lazy to do test.
Thanks
