YOUR database crashes after a user accidentally kills a background process. What are three possible ways to
restart your database?
A.
S sqlplus / as sysdbaSQL> restart;
B.
S sqlplus / as sysdbaSQL> startup immediate;
C.
S rman target /RMAN> Startup
D.
S sqlplus / as sysdbaSQL> startup open recover;
E.
S srvctl start database -db SORACLE_SID
Explanation:
The following command starts an instance, reads the initialization parameters from the default location, and
then mounts and opens the database. (You can optionally specify a PFILE clause.)
STARTUP
If you know that media recovery is required, you can start an instance, mount a database to the instance, and
have the recovery process automatically start by using the STARTUP command with the RECOVER clause:
STARTUP OPEN RECOVER
To start or stop your entire cluster database, that is, all of the instances and its enabled services, enter the
following SRVCTL commands:
$ srvctl start database -db db_unique_name [-startoption start_options]
