This must be a joke? Did I travel in time to April the 1st? 10 instances on a single machine is a "consolidation"? Why would anyone want to have 10 sets of background processes, 10 SGA areas and many wasted semaphores? Why is schema separation not enough? Are you coming from the MS SQL Server world? Such fascination with many databases is usually characteristic for the people with SQL Server background. While SQL Server is a great database, especially for DW purposes, its architecture is very much unlike Oracle, which prefers a single database.
