Au contraire mon ami.
In Oracle the database does not consist of processes and buffers or anything of the kind. The "database" is a set of related physical files ... data files, temp files, undo files, control files, redo log files, password file, spfile. What you are describing is the "instance."
Get into RAC with srvctl and the difference becomes critical.
