1.proflie优势

使用profile可以批量管理用户参数,尤其是在一批用户具有相同的参数配置时,十分便捷。

2.profile可配置用户参数

【Account id】【Default database】:用户下次登录或用户提交SET SESSION ACCOUNT命令时生效。

【Spool space】【Temporary space】:立即生效。

【Password】:用户下次登录时生效。

3.赋予操作proflie权限

grant create profile,drop profile to citic_edw with grant option;

4.创建修改删除查询proflie(profileemployee_p)

create profile employee_p as account='';
modify profile employee_p as account='';
drop profile employee_p;
select * from dbc.profileinfov; --查看profile信息
select * from dbc.AccountInfoV; --查看用户account信息
select user,role,profile,database; --查看当前用户信息

5.用户使用指定profile(profileemployee_p或NULL)

create user Emp01 as …, profile = employee_p;
modify user Emp02 as profile = employee_p;
modify user Emp03 as profile=NULL;

6.用户参数生效优先顺序

(1)指定session级别的Database或者Account id

(2)Profile中的指定的用户参数

(3)CREATE USER or MODIFY USER语句指定的用户参数

7.创建profile完整实例

CREATE PROFILE Employee_P AS
ACCOUNT = ('$M0_EDUC&S&D&H', '$L0_EDUC&S&D&H')
DEFAULT DATABASE = HR_VM
SPOOL = 1E9
TEMPORARY = 500E6
PASSWORD = ( EXPIRE = 90, MINCHAR = 8, MAXLOGONATTEMPTS=3, LOCKEDUSEREXPIRE = 60, REUSE = 180, DIGITS = 'R', RESTRICTWORDS = 'Y', SPECCHAR = 'P');
