Oracle用户及角色的权限管理[Oracle基础]

1.查看所有用户：

  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(只能查看登陆用户拥有的角色)所包含的权限

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.查看所有角色：

  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(查询时需要相应权限)

    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权限其实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
