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
select * from V$PWFILE_USERS
