I think this is a quick question. As I'm going through the hugepages information, I'm trying to figure out if you can, or cannot, have multiple instances on 1 host running different configurations? Such as DB_1 running hugepages (32GB SGA) DB_2 running regular pages (4GB SGA) It seems that all instances will need to be in hugepages?
