db instances and data warehouse
Currently running 11gr2. We have a vendor app consisting of several schemas including a data warehouse one which we've installed all within one db instance. We are seeing some performance issues and are wondering if moving the warehouse to its own instance would improve things ? The vendor did state that they support using separate db instances (eg. one per schema) but don't have any performance stats on the different db typologies (one instance vrs several)
What are the pro's /cons ? Our first though was to move only the data warehouse to its own instance.
