1.) Logon to the product database as the SYSTEM user (not the application administration user).
2.) Find the profile that has the PASSWORD_LIFE_TIME set to anything but UNLIMITED.
SQL> select * from dba_profiles where RESOURCE_NAME LIKE 'PASSWORD_LIFE_TIME';
If the user name say "test" and password is also "test" then check the profile assign to the user as
SQL>select username,profile from dba_users where username='TEST' ;
Once ,we have profile, we alter the profile and password .
3.) Alter the profiles with the following statement:
SQL> alter user test identified by test account unlock ;
SQL> alter profile profile_name limit PASSWORD_LIFE_TIME UNLIMITED;
where profile_name is the name of the profile where wer need to set the password life to UNLIMITED.
This should remove the password life message.
