一、profile管理
1、profile创建

create profile fei_profile limit
 sessions_per_user 1
 cpu_per_session 30000
 cpu_per_call 600
 connect_time 300
 idle_time 60
 logical_reads_per_session 300
 logical_reads_per_call 100
 failed_login_attempts 2
 password_life_time 1
 password_reuse_time 3
 password_reuse_max 10
 password_lock_time 1;

2、修改profile

alter profile fei_profile limit
connect_time 400
idle_time 200;

3、删除profile

drop profile fei_profile;

二、创建用户
1、准备工作

--查看表空间
select tablespace_name,contents from dba_tablespaces;
--查看默认临时表空间
select * from database_properties where property_name like '%TEMP_TABLE%';

2、创建用户
2.1数据库认证

create user abc
identified by abc
default tablespace abc
temporary tablespace temp
quota 10m on abc
quota 5m on users
password expire
account lock;

2.2、操作系统认证

--查看os_authent_prefix（前缀+操作系统用户名=数据库登陆名）
show parameter os_aut--查看结果为：OPS$
--创建用户
create user OPS$ff identified externally default tablespace abc;

三、修改用户

alter user abc account unlock;

四、删除用户

drop user abc cascade;--表示删除该用户下的所有objects

五、授权和回收
5.1、system级别权限

grant create session,create table to abc with admin option;--可以传递该授权（续传的权限不会被回收）
revoke create session,create table from abc;
grant create session,create table to fei identified by fei;
--用户不存在直接创建该用户，存在则修改用户密码

5.1.1权限类型

select * from session_privs;--查看本用户所具有的权限

--note：如果授权select any table 在默认情况下不能访问数据字典（O7_DICTIONARY_ACCESSIBILITY=false）
--如果修改O7_DICTIONARY_ACCESSIBILITY=true则可以访问数据字典

5.2、object级别授权与回收

grant select,update,delete on abc.abc_a to abc with grant option;--权限可以传递（如果被回收，续传下去的权限一并回收）
grant all on fei_a to abc;--把fei_a的所有相关操作授权给abc
revoke  select,update,delete on abc.abc_a from abc;
--note：update，insert可以指定表的列，而select不行，只能通过view实现限制功能

六、role的管理
6.1、role的创建

create role r_a;
create role r_b identified by r_b;

6.2/授权

grant create session to r_a;
grant create table to r_b;
grant r_a,r_b to b;--b为用户，把role授权给用户

6.3、查看role相关信息

select * from role_tab_privs where  ROLE LIKE 'R_%';
SELECT * FROM ROLE_SYS_PRIVS WHERE ROLE LIKE 'R_%';
SELECT * FROM ROLE_ROLE_privs where role like 'R_%';

6.4、设置default role 和enabl/disable role

alter user b default role r_a;
set role r_a,r_b identified by r_b;
--使用b用户登录，然后enable role r_a,r_b(注意密码)
--没有在set中写出来的role，表似乎disable
