24题、You issue commands in SQL*Plus as the Oracle owner, to enable multithreading for your UNIX-based Oracle 12c database:

CONNECT/AS SYSDBA

ALTER SYSTEM SET THREADED__EXECUTION= TRUE SCOPE=SPFILE;

SHUTDOWN IMMEDIATE

You then restart the instance and get an error:

STARTUP

ORA-01031: insufficientprivileges

Why does the startup command return the error shown?

A. because the threaded architecture requires exiting from sql*pIus and reconnectingwith sql*PIus / as sysDBA before issuing a startup command

B. because the threaded architecture requires issuing a new connect / as sysDBA from within sql*pIus before issuing a startup command

C. because the threaded architecture requires authentication using a password file before issuing a startup command

D. because the threaded architecture requires connecting to the instance via a listener before issuing a startup command

E. because the threaded architecture requires restarting the listener before issuing astartup command

Answer: C

(解析：答案 C 的意思是登录时需要用 sys 用户的名字登录然后启动实例，因为使用密码文件意味着需要使用 sys 用户，需要用如下方式进行启动：

1、sqlplus /nolog

2、SQL> conn sys/oracle as sysDBA

3、SQL> startup

)
