=========================================================

Solutions:-

1)Change the profile limit and make the same password

SQL>  select USER#,NAME,PASSWORD FROM user$ where name='BACMONIT';

     USER# NAME                           PASSWORD

---------- ------------------------------ ------------------------------

        99 BACMONIT                    XXXXXXX

2)Check the PASSWORD_REUSE_TIME.

SQL>  select * from dba_profiles where profile='DBUSER' and  RESOURCE_NAME in ('PASSWORD_REUSE_TIME') ;

PROFILE                        RESOURCE_NAME                    RESOURCE

------------------------------ -------------------------------- --------

LIMIT

----------------------------------------

DBUSER                         PASSWORD_REUSE_TIME              PASSWORD

360

3)Change the profile limit to unlimited.

SQL>  alter profile DBUSER limit PASSWORD_REUSE_TIME UNLIMITED;

Profile altered.

4)Change the password with used one.

SQL>  alter user BACMONIT IDENTIFIED BY VALUES 'xxxxxxx';

User altered.

5)Revert back the limit.

SQL> alter profile DBUSER limit PASSWORD_REUSE_TIME 360;

Profile altered.

6)Check the password expiry date 

SQL> select username,account_status,EXPIRY_DATE from dba_users where username='BACMONIT';

USERNAME                       ACCOUNT_STATUS                   EXPIRY_DA

------------------------------ -------------------------------- ---------

BACMONIT                       OPEN                             29-DEC-13
