HTTP Status [404] – [Not Found]
Check in Tomcat Web Application Manager that the ORDS application is started. Click the [Start] button if necessary... watch for any startup errors that will appear at the top of the screen.
Check the permissions on /u01/app/ords are correct. If /u01/app/ords is owned by 'oracle' and Tomcat is owned by 'tomcat' there are likely to be issues at startup.
Check that the database is functioning correctly. If there are database issues, this is often reflected as a 404 error in ORDS.
Deinstall

cd /u01/app/ords
