Oracle Server statup modes

Startup Modes

startup nomount Starts the Instance—Creates the SGA and runs the background
processes after reading the parameters in the
init.ora (Instance configuration) file.
startup mount Starts the Instance and mounts the database—Reads the
control file and identifies the Database files.
startup open Starts the Instance and allows access to the Database for
users via the Oracle Server.
startup force Performs a shutdown abort, followed by a startup open.
Note that startup force is an option, not a mode.
