Servlet is always shut down

Question

if the user(s) is using the servlet, everything works. but when the user stops working, approximately 2-3hours after the last user action our servlet is stopped (the container shuts down). it restarts of course when the user tries to access it again, but our servlet does a lot of background computation for a long time. it shouldn't be shut down. it has to run all the time. maybe there is a setting in oracle which shuts down unused servlets?

Answer 1

There is a timeout you can specify in web console. It counts since last user accessed servlet and than servlet is removed from memory. Default is maybe 60 minutes?Probably nobody assumed some servlet can do work in background for such a long time.
