Ok, from here, it shows idle instance is dynamic instance in your view. Then what do min-idle-instances and max-idle-instances mean in the config file? Then how to set the number of resident/reserved instances in config file? > > Here is a list of instances from a low traffic site > > *Instances *[image: > help]<https://developers.google.com/appengine/docs/adminconsole/instances> > QPS*Latency*RequestsErrorsAgeMemoryApp Engine ReleaseLogsAvailability > Shutdown0.0000.0 ms29502 days, 5:44:0869.8 MBytes1.8.9 > [image: Resident Icon]Resident > 0.050350.7 ms1546016:34:2155.3 MBytes1.8.9 > [image: Dynamic Icon]Dynamic > 0.0000.0 ms5302:37:2470.6 MBytes1.8.9 > [image: Dynamic Icon]Dynamic > > Look at your instances chart to see what you aggregate instance time you > are being billed for. > > If you really want to keep under the 28 hours (I have done it in the past) > (you probably shouldn't use java ;-). > REALLY!? yes, I'm really disappointed with GAE Java, but any GAE team googler can confirm this? > > - Don't have a reserved instance, set idle instances to one, and run a > external wget every minute or so to keep a single instance alive. > > Ok, ask it again: how to set the number of resident/reserved instances in config file?
