Re: Best practice for Dataguard in 10g?

we are running quite happily with arch log shipping. Can not comment on lgwr shipping as I have not tried that yet.

but ....

I don't work with Data Warehouses very much but don't they have a lot on non logged operations normally? Dataguard does not like these.

enabling logging may be a performance hit.

just some extra thoughts
