Since Oracle Database 10g, the DROP DATABASE
command can be used to delete the database files listed in the database control
file as well as the control file itself.
Database Initialization
At Oracle database instance startup, initialization parameters are read to determine
how the database will leverage physical infrastructure and for other key instance
configuration information. Initialization parameters are stored in an instance initialization
parameter file, often refered to as INIT.ORA, or, since Oracle9i, in a
repository called the server parameter file (or SPFILE). The number of initialization
parameters that must be specified has been greatly reduced with each Oracle database
release. Oracle provides a sample initialization file that can be used at database
startup, and the Database Configuraton Assistant (DCA) prompts you for values that
must be provided on a custom basis (such as database name).

DB_NAME
The local database name
DB_DOMAIN
The database domain name (such as us.
