Check User Account Status :

 select username,account_status,expiry_date,profile from dba_users where username='SYSTEM';

USERNAME                       ACCOUNT_STATUS                   EXPIRY_DA PROFILE
------------------------------ -------------------------------- --------- ------------------------------
SYSTEM                         EXPIRED(GRACE)                   06-SEP-13 DEFAULT


Check the Profile limit set for password life time

select * from dba_profiles where RESOURCE_NAME='PASSWORD_LIFE_TIME';

PROFILE                                  RESOURCE_NAME                  RESOURCE LIMIT
---------------------------------------- ------------------------------ -------- -------------------------
DEFAULT                                  PASSWORD_LIFE_TIME             PASSWORD 180

If you dont want to alter the profile limit set, then change the password for the user by noting it values from user$ and then reset it back.

If you wanna change the profile limit then,

Alter profile default limit password_life_time unlimited;

SQL> Alter profile default limit password_life_time unlimited;

Profile altered.

select * from dba_profiles where RESOURCE_NAME='PASSWORD_LIFE_TIME';

PROFILE                                  RESOURCE_NAME                  RESOURCE LIMIT
---------------------------------------- ------------------------------ -------- -------------------------
DEFAULT                                  PASSWORD_LIFE_TIME             PASSWORD UNLIMITED

After changing the profile limit also the user account will be in expired status only,

USERNAME                       ACCOUNT_STATUS                   EXPIRY_DA PROFILE
------------------------------ -------------------------------- --------- ----------------------------------------
SYSTEM                         EXPIRED(GRACE)                   06-SEP-13 DEFAULT

Now change the password you would like or use the same password to set.

Alter user system identified by pass_word;

SQL> Alter user system identified by pass_word;

User altered.

SQL> select username,account_status,expiry_date,profile from dba_users where username='SYSTEM';


USERNAME                       ACCOUNT_STATUS                   EXPIRY_DA PROFILE
------------------------------ -------------------------------- --------- ----------------------------------------
SYSTEM                         OPEN                                       DEFAULT
