# Directory of the database respectively. The third filed indicates

The last n or y indicates whether the Dbstart is allowed to start the database, and if n is not enabled through Dbstart, the Sqlplus connection instance is displayed connected to an idle instance. If the instance of Y is enabled through Dbstart, the database will be open after the sqlplus is connected.
