A

This is Step 6. Now you are ready to start the new Oracle Instance without any database. This instance will be used to create a database. Starting an instance without database can be done by using STARTUP NOMOUNT statement as shown below:

>.\bin\sqlplus /nolog

SQL> CONNECT / AS SYSDBA
Connected.

SQL> SHUTDOWN
ORACLE instance shut down.

SQL> STARTUP NOMOUNT
ORA-00821: Specified value of sga_target 16M is too small, 
needs to be at least 20M

The SHUTDOWN command is need to bring the default instance XE down.

The STARTUP NOMOUNT command failed because it tried to start the default instance XE, and there is a bad parameter in the XE instance SPFile.

See the next FAQ question to find another way to start the new instance FYI.
