username    sysdb    sysop    sysas     sysdg    sysem    con_id

-----------------------------------------------------------------------

sys true true false false false  0

Which two tasks must you perform to add users with SYSBACKUP, SYSDG, and SYSKM privilege to the password file?

A. Assign the appropriate operating system groups to SYSBACKUP, SYSDG, SYSKM.

B. Grant SYSBACKUP, SYSDG, and SYSKM privileges to the intended users.

C. Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege and the FORCE argument set to No.

D. Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege, and FORCE arguments set to Yes.

(解析： Administrative Privileges

Administrative privileges that are required for an administrator to perform basic

database operations are granted through the following special system privileges:

■ SYSDBA

■ SYSOPER

■ SYSBACKUP

■ SYSDG

■ SYSKM

您必须拥有其中一个授予您的特权，这取决于您需要的授权级别。

从 Oracle 数据库 12c 开始，可以使用 SysBackup、SysDG 和 SysKM 管理权限。每个新的管理权限都授予完成每个管理领域任务所需的最低权限。新的管理权限使您能够避免授予 sysdba 管理权限对于许多常见的任务。

查询使用密码文件是用户：

SQL> select * from v$pwfile_users;
