Oracle 11g Password Features

If a specific profile is not assigned to a given database user,
then the default profile will be assigned to that user. The
password related settings for the default profile have changes in
Oracle 11g as shown in the following table:

Resource Name	Oracle Database 10g	Oracle 11g
Failed_login_attempts	10	10
Password_grace_time	Unlimited	7 (days)
Password_life_time	Unlimited	180
Password_lock_time	Unlimited	1 (days)
Password_reuse_max	Unlimited	Unlimited
Password_reuse_time	Unlimited	Unlimited

You can see these new settings by issuing the following
query:

SELECT profile, resource_name, limit
FROM dba_profiles
WHERE profile='DEFAULT';

ALTER USER SYSMAN IDENTIFIED BY <password>;

ALTER PROFILE DEFAULT LIMIT password_life_time UNLIMITED;

  

SELECT username,ACCOUNT_STATUS,EXPIRY_DATE FROM dba_users;
