24題、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 的意思是登錄時需要用 sys 用戶的名字登錄然后啟動實例，因為使用密碼文件意味著需要使用 sys 用戶，需要用如下方式進行啟動：
1、sqlplus /nolog
2、SQL> conn sys/oracle as sysdba
3、SQL> startup
)
