    oracle11g密码复杂性校验开启关闭
    oracle11g密码复杂性校验由参数PASSWORD_VERIFY_FUNCTION控制
    开启密码复杂性校验
    
SQL> @?/rdbms/admin/utlpwdmg.sql
Function created.
Grant succeeded.
Profile altered.
Function created.
Grant succeeded.

SELECT * FROM Dba_Profiles d WHERE d.profile='DEFAULT';

    
SQL> alter user syd identified by syd;
alter user syd identified by syd
*
ERROR at line 1:
ORA-28003: password verification for the specified password failed
ORA-20001: Password length less than 8
SQL> alter user syd identified by Sydoracle123;
User altered.
SQL> alter user syd identified by syd;
alter user syd identified by syd
*
ERROR at line 1:
ORA-28003: password verification for the specified password failed
ORA-20001: Password length less than 8

    关闭密码复杂性校验
    
SQL> alter profile default limit PASSWORD_VERIFY_FUNCTION null;
Profile altered.

SELECT * FROM Dba_Profiles d WHERE d.profile='DEFAULT';

    
SQL> alter user syd identified by syd;
User altered.
SQL> alter user syd identified by oracle;
User altered.

    utlpwdmg.sql脚本中有如下一段内容：
    
ALTER PROFILE DEFAULT LIMIT
PASSWORD_LIFE_TIME 180
PASSWORD_GRACE_TIME 7
PASSWORD_REUSE_TIME UNLIMITED
PASSWORD_REUSE_MAX UNLIMITED
FAILED_LOGIN_ATTEMPTS 10
PASSWORD_LOCK_TIME 1
PASSWORD_VERIFY_FUNCTION verify_function_11G;

    运行了以上脚本后，在开启了密码校验性的同时，oracle密码期限也被改回了默认的180天，若需要密码不过期别忘更改：
    
SQL> alter profile default limit PASSWORD_LIFE_TIME unlimited;
Profile altered.

    总结
    以上为个人经验，希望能给大家一个参考，也希望大家多多支持电脑手机教程网。
