How to keep an App Engine/Java app running with deaf requests from a Java/Python web cron?

Question

1. App Engine allows you 30 seconds to load your application
2. My application takes around 30 seconds - sometimes more, sometimes less. I don\'t know how to fix th

Answer 1

App engine also has a new PAY feature where you can have it "always-on". Costs about $0.30 USD cents a day. Just go into your billing settings and enable it if you don't mind paying for the feature. I believe it guarantees you at least 3 instances always running.

(I didn't realize hitting a /ping url which caused an instance to spin up would cause it to exceed the 30 sec limit!)

Answer 2

It would probably be easier use the cron built in to App Engine to keep your application alive.

Answer 3

I think what you want is just:

import httplib
hcon = httplib.HTTPConnection("foo.appspot.com")
hcon.request("GET", "/someURL")
hcon.close()

Answer 4

the simplest Java http pinger:

URLConnection hcon = new URL("http://www.google.com").openConnection();
hcon.connect();
hcon.getInputStream().read();
