Fix ORA-28011: the account will expire soon; change your password now
1. check user profile
SQL>select USERNAME,ACCOUNT_STATUS,PROFILE from dba_users where USERNAME = <USERACCOUNT>;
2. view Profile setting and change expire parameter to unlimit
SQL>select * from dba_profiles where profile = <USER_PROFILE>;
SQL>alter profile <USER_PROFILE> LIMIT PASSWORD_LIFE_TIME UNLIMITED;
3. change password and commit
SQL> alter user <username> identified by <passwd>;
SQL> commit;
