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.
