【12c】oracle12c 的SYSBACKUP、SYSDG、SYSKM系统用户
作者：互联网
oracle12c 推出了三个新的系统用户SYSBACKUP、SYSDG、SYSKM，下面文章源自官方文档
1、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
You must have one of these privileges granted to you, depending upon the level of
authorization you require.
Starting with Oracle Database 12c, the SYSBACKUP, SYSDG, and SYSKM administrative
privileges are available. Each new administrative privilege grants the minimum
required privileges to complete tasks ineach area of administration. The new
administrative privileges enable you to avoid granting SYSDBAadministrative privilege
for many common tasks.

SYSBACKUP
概念
A new administration privilege, SYSBACKUP, allows Recovery Manager (RMAN) users to connect to the target database and run RMAN commands, no longer requiring SYSDBA. This feature enforces the separation of duty security model, whereby backup operators only need SYSBACKUP privilege to run RMAN commands and have separate responsibilities from database administrators who need real SYSDBA privileges. 一个新的管理特权，SYSBACKUP，允许Recovery Manager(RMAN)用户连接到目标数据库，并运行RMAN命令，不再需要SYSDBA。 这一特性强制执行了职责安全模型的分离，即备份操作符只需要SYSBACKUP权限来运行RMAN命令，并从需要真正的SYSDBA特权的数据库管理员那里承担独立的职责。 RMAN连接到数据库的方式与SQL*Plus连接到数据库的方式相同。唯一的区别是，RMAN连接到目标或辅助数据库需要SYSDBA或SYSBACKUP特权。任何用户都可以授予此特权。
实验
以下操作是在Oracle 12.1.0.2.0 版本数据库中操作 1) 给PDB 用户test 赋予sysdba 权限，RMAN两种方式连接目标数据库，并操作RMAN 命令 SQL> grant sysdba to test; Grant succeeded.

RMAN> connect target test/test@pdbcndba connected to target database: CNDBA (DBID=215559030) 2）PDB 用户 cndba 赋予sysbackup 权限，RMAN后面一种方式连接目标数据库，并操作RMAN 命令 SQL> create user cndba identified by cndba 2 / User created. SQL> grant sysbackup to cndba; Grant succeeded.
