Oracle用户及角色的权限管理[Oracle基础]

1.查看全部用户：
  select * from dba_users;
  select * from all_users;
  select * from user_users;
2.查看用户或角色系统权限(直接赋值给用户或角色的系统权限)：
  select * from dba_sys_privs;
  select * from user_sys_privs;
3.查看角色(仅仅能查看登陆用户拥有的角色)所包括的权限
sql>select * from role_sys_privs;
4.查看用户对象权限：
  select * from dba_tab_privs;
  select * from all_tab_privs;
  select * from user_tab_privs;
5.查看全部角色：
  select * from dba_roles;
6.查看用户或角色所拥有的角色：
  select * from dba_role_privs;
  select * from user_role_privs;
7.查看哪些用户有sysdba或sysoper系统权限(查询时须要对应权限)
    SQL> select * from dba_role_privs where grantee='CX_ZJ_ROS';                  -------------用户所拥有的角色
  GRANTEE      GRANTED_ROLE   ADM  DEF
  ----------  --------------- ----- ----
  CX_ZJ_ROS ZHRO NO  YES
SQL> SELECT * FROM DBA_SYS_PRIVS WHERE GRANTEE='ZHRO';       --------这里查询的是用户和自己定义角色所拥有的权限                                                                      
GRANTEE   PRIVILEGE      ADM
-------- ------------ -------------------
ZHRO   CREATE SEQUENCE   NO
ZHRO   CREATE SESSION    NO
ZHRO    CREATE TABLE     NO
ZHRO   UNLIMITED TABLESPACE  NO  

 5 rows selected.

------------这里的UNLIMITED TABLESPACE权限事实上是不能通过角色的方式授予的     

SQL> select * from role_sys_privs where role='CONNECT';    
-------这里查询的是系统角色所拥有的权限
ROLE       PRIVILEGE        ADM
--------- ---------------- ----------
CONNECT    CREATE SESSION   NO
SQL> SELECT * FROM DBA_SYS_PRIVS WHERE GRANTEE='ILOG_RTS';
GRANTEE    PRIVILEGE             ADM
--------- --------------------- -------------
ILOG_RTS   UNLIMITED TABLESPACE  NO
SQL> select * from dba_role_privs where grantee='ILOG_RTS';
GRANTEE    GRANTED_ROLE        ADM DEF
---------- -------------       --- ---
ILOG_RTS   CONNECT              NO  YES
ILOG_RTS    RESOURCE            NO  YES
select * from V$PWFILE_USERS
