503 "service unavailable" error
Autonomous database stops responding after a few minutes and gives 503 "service unavailable" error
I am an instructor in a college and I requested cloud accounts for my students in the class. Several student accounts keep having this problem - after running a few simple queries, the database will stop responding. They have to restart the database to get it to work, but it will halt again after a few minutes. When they refresh the page, they will see this 503 error. Can anybody help with this problem? Any suggestion is appreciated!
