possible to use an exceptions table in parallel?

http://www.jlcomp.demon.co.uk/faq/duplicates.html

I do not know how to do an

'alter table add unique constraint' in parallel.

the only way I know how to use parallel is with a 'create index'. Problem is
'exceptions into' does not seem to work with this statement.

I have a big table. Anyway to use the exceptions table with the parallel clause? if not it will run for hours.
