My trial period of Oracle Cloud Autonomous Database with Apex has ended and the always free resource - DB and Apex keeps turning itself off even if in use.
Even if manually started, it shuts down within 10 minutes.
I created a simple Apex app, multiple tables, jobs, email services (now disabled as trial is over) and several web services to create a POC, however it shuts itself off unexpectedly even if e.g. working with Apex developer, running the Apex app or firing up the web services through Postman.
So now I am confused, is it free or not, where are the logs showing if there is a problem with my code, DBMS_JOBs or something that would cause the DB to shutdown ?
