标题:PASSWORD_ROLLOVER_TIME—实现新老密码短期共存

作者:惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

在oracle老版本中(特别是11g版本),你可能多少都遇到过应用修改密码,但是由于系统运行应用较多,在修改应用密码的过程中有业务忘记修改密码,从而导致业务无法正常使用,甚至由于密码延迟认证特性导致数据库hang住,对于这些问题,oracle 从19.12开始引入了PASSWORD_ROLLOVER_TIME,可以在这个profile限制时间内,新老密码都可以登录数据库,避免了上述问题.
在手上有的23ai的数据库中进行测试,创建一个测试用户,使用的是default profile,PASSWORD_ROLLOVER_TIME为0(没有启用)

SQL> select banner from v$version;

SQL> create user xff identified by oracle;

User created.

SQL> grant dba to xff;

Grant succeeded.

SQL> select profile from dba_users where username='XFF';   

PROFILE
------------------------------

SQL> select profile,limit from dba_profiles where resource_name='PASSWORD_ROLLOVER_TIME';

PROFILE                        LIMIT

ORA_CIS_PROFILE                DEFAULT
ORA_STIG_PROFILE               DEFAULT

尝试修改密码,尝试登录(老密码无法登录成功)
