Posted by I got a nasty shock this morning when I fired up my local Application Expression installation.
It had been working fine and all of a sudden…just dead. I sounded like all of those family members that as I.T practitioners we have to deal with (and that we’re so sceptical of) when they say: “I didn’t change anything…it just stopped!” 
In keeping with the treatment of family members, I then adopted the advice that I normally give them first.
and upon restart, I saw the following during the startup

Since security is our #1 thing for 2019 and probably should be the #1 item on your agenda for 2019, this was caused by some improvements to the Oracle defaults when you perform a database installation. Rather than the default being an “flexible” (aka loose ) policy we used to have when it comes to password management, we’ve gone for some more sensible options out of the box.
SQL> select * from dba_profiles order by 1,2
PROFILE RESOURCE_NAME RESOURCE LIMIT
---------------- -------------------------------- -------- -----------
DEFAULT COMPOSITE_LIMIT KERNEL UNLIMITED
DEFAULT CONNECT_TIME KERNEL UNLIMITED
DEFAULT CPU_PER_CALL KERNEL UNLIMITED
DEFAULT CPU_PER_SESSION KERNEL UNLIMITED
DEFAULT FAILED_LOGIN_ATTEMPTS PASSWORD 10
DEFAULT IDLE_TIME KERNEL UNLIMITED
DEFAULT INACTIVE_ACCOUNT_TIME PASSWORD UNLIMITED
DEFAULT LOGICAL_READS_PER_CALL KERNEL UNLIMITED
DEFAULT LOGICAL_READS_PER_SESSION KERNEL UNLIMITED
DEFAULT PASSWORD_GRACE_TIME PASSWORD 7
DEFAULT PASSWORD_LIFE_TIME PASSWORD 180

DEFAULT PASSWORD_REUSE_MAX PASSWORD UNLIMITED
DEFAULT PASSWORD_REUSE_TIME PASSWORD UNLIMITED
DEFAULT PASSWORD_VERIFY_FUNCTION PASSWORD NULL
DEFAULT PRIVATE_SGA KERNEL UNLIMITED
DEFAULT SESSIONS_PER_USER KERNEL UNLIMITED
So if you want your APEX public accounts (and I stress, no others!) to have a non-expiring password, then you should create a custom profile for those accounts and assign them accordingly.
create profile no_expire
limit password_life_time unlimited;
alter user apex_public_user profile no_expire ;
alter user apex_rest_public_user profile no_expire ;
alter user apex_listener profile no_expire ;
alter user ords_public_user profile no_expire ;
This will ensure you don’t get an unexpected drama next time you want to fire up Application Express.
Learning is not a spectator sport 
Same goes for DBSNMP, ORDS_PLUBLIC_USER etc. 🙂
It’s early. Just saw you included ORDS_PLUBLIC_USER. 🙂
Hmm, I read about that somewhere …. Seems many of us get bit by this once, THEN set those profiles or reminders. #BeenThereDoneThat

Trying to see some reference material Anaytic SQL in one of your youtube series and I got the 404 Not Found screen you mention here. All your reference links fail. For example https://www.youtube.com/redirect?event=video_description&v=eRk-NVe3I5Q&redir_token=AVgAe_IB4W859EKCz9b_UzP8-fh8MTU0NzQyMTMzOEAxNTQ3MzM0OTM4&q=https%3A%2F%2Flivesql.oracle.com%2Fapex%2Flivesql%2Fs%2Fcokv9220ffzt8iqs7udqsv5vm
Can you fix these permissions?
Thanks!
Alan
