If an instance is created by allocating memory areas and starting background processes then what is an "idle instance" when no oracle database is up and running? No background process exists yet, no memory is allocated but this thingy is called an instance (idle one). Sometimes database is up and running and one still can connect to "idle instance". Isn't a kind of word play here and actually "idle instance" means something different than "real instance"? Can "connected to idle instance" be understood as equivalent of "not connected to `real' instance"?
