Re: [google-appengine] Intermittent App latency
Hi Cian, Have you used Appstats to investigate? Perhaps there is some type of cleanup process, maybe by a session library, happening?

[google-appengine] experiencing latency issues on my app.
app-id: mr-october, always on. I have posted messages here for the last 2 days that seem to have gone into a moderator black hole. My app seems to have random latency, All but one of these time outs happen prior to any of my code executing, the other times out in a data store fetch. Here is the log message from the calls: 2011-02-24 11:52:33.837 A serious problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you should contact the App Engine team.

[google-appengine] Google Apps verification on Domain
Hi Recently, I started migrating email to Google Apps for Business. MX and CNAME records for mail on my domain is now pointing to Google. 1. I can't use Google Apps because Google needs 48 hours to verify my domain. Is there a quicker way on the verification process ? 2. Also, how do I access Google Apps Admin Cpanel when there is no option to create Admin ID and password ? I need my email to get started on Google in th next 6 hours, I appreciate anyone who can assist me on this. There is no way I can contact Google for technical support by phone, the 1st response from Google is the asking of PIN number which is not easily available. Best Regards ERIC -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to google-appengine@googlegroups.com.

[google-appengine] Application latency spikes.
My app (appid: mr-october) is experiencing lots of problems with latency spike. I am paying for always on service. I am seeing frequent but seemingly random spikes of latency on user requests. This is causing my users lots of unexpected problems and giving the app a reputation as unreliable. Currently I get 20-50 users to the site everyday spread out over the day. Looking at my logs I ca find an example of this. When users land on my site I present them with a list of available options. this is done by query the data store for objects that have an end date in the future and then doing a little additional filtering on the list. The current list is about 8 returned from the data store and then filtered on the cpu and sanatized to be sent to the user. Over the last 3 hours I find the following latencys for this call, (which i can identify by the first log entry of :com.shinypurplepony.reggie.server.servlets.RegistrationServlet execute: Action: com.shinypurplepony.reggie.shared.action.GetRegistrationSeasons) 2011-02-25 12:36:09.581 /reggie/dispatch 200 4829ms 4763cpu_ms 236api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.82 Safari/ 534.16,gzip(gfe 2011-02-25 12:35:31.683 /reggie/dispatch 200 159ms 405cpu_ms 125api_cpu_ms 6kb Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB0.0; SLCC2; .NET CLR 2.0.50727; 2011-02-25 12:35:16.764 /reggie/dispatch 200 354ms 615cpu_ms 125api_cpu_ms 6kb Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB0.0; SLCC2; .NET CLR 2.0.50727; 2011-02-25 12:20:37.208 /reggie/dispatch 200 232ms 452cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 2011-02-25 12:19:28.348 /reggie/dispatch 200 6380ms 4600cpu_ms 190api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 2011-02-25 10:47:19.700 /reggie/dispatch 200 171ms 452cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.2.13) Gecko/20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:47:15.865 /reggie/dispatch 200 141ms 405cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.2.13) Gecko/20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:47:15.731 /reggie/dispatch 200 385ms 475cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.2.13) Gecko/20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:46:52.893 /reggie/dispatch 200 37ms 140cpu_ms 0kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/ 20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:37:15.031 /reggie/dispatch 200 177ms 522cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 2011-02-25 10:36:48.890 /reggie/dispatch 200 3550ms 732cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) Which is honestly much better then the past couple of days: 2011-02-25 08:55:09.606 /reggie/dispatch 500 30302ms 86cpu_ms 40api_cpu_ms 0kb Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 1.1.4322; InfoPath.2; MS-2011-02-22 22:23:31.143 /reggie/dispatch 200 5043ms 210cpu_ms 0kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.13 (KHTML, like Gecko) Chrome/9.0.597.98 Safari/534.13,gzip(gfe) Or these where appengine did not even get to my log statement so I have no idea what the request was: 2011-02-23 09:36:35.922 /reggie/dispatch 500 141862ms 1395cpu_ms 65api_cpu_ms 0kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_6; en- us) AppleWebKit/533.19.4 (KHTML, like Gecko) Version/5.0.3 Safari/ 533.19.4,gzip(gfe) 2011-02-23 09:00:21.024 /reggie/dispatch 500 102858ms 793cpu_ms 0kb Mozilla/5.0 (iPad; U; CPU OS 4_2_1 like Mac OS X; en-us) AppleWebKit/ 533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8C148 Safari/ 6533.18.5,gzip(gfe) What can be do to address these latency issues?

[google-appengine] Newbie playing around with GAE+Maven+Spring+JPA
Hello, I'm totally newbie in GAE, and I come from a relational database system... I'm using JPA for persistence just because I'm used to working with Hibernate... I have main doubts which are prevening me from figuring out all the GAE stuff: I just complete an example application which runs locally with maven GAE plugin (mvn gae:run) and I'm testing some persistence stuff. My issue (ignorance) comes from the fact that in one execution I insert, for example, two users, and in the following I would like to query them: between executions I don't have "persistence", I have to insert them again. The question is basically how to "explore" the datastore locally, without deploying in GAE, during the development phase, and get some data inserted and "maintain" this data between the hundreds of executions needed to test and develop the app. There has to be some file/s with the data (locally) and populate it with example data, along with the information I am incorporating through the forms of the application I'm not sure if I've explained it well, but I just want to try my application locally using maven plugin and get the data "persisted" without having to insert the same entities over and over again.

[google-appengine] Application latency issues.
Hi, tried to post this twice yesterday and have not seen any response or posting to the forums. At this point I am completely baffled as how to get any support on appengine. -- Content old due to "lost messages" My app (appid: mr-october, always on) is experiencing lots of problems with latency problems over the last couple of days. For a bunch of the calls to the same dispatch handler over the last there hours. 2011-02-25 12:36:09.581 /reggie/dispatch 200 4829ms 4763cpu_ms 236api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.82 Safari/ 534.16,gzip(gfe 2011-02-25 12:35:31.683 /reggie/dispatch 200 159ms 405cpu_ms 125api_cpu_ms 6kb Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB0.0; SLCC2; .NET CLR 2.0.50727; 2011-02-25 12:35:16.764 /reggie/dispatch 200 354ms 615cpu_ms 125api_cpu_ms 6kb Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB0.0; SLCC2; .NET CLR 2.0.50727; 2011-02-25 12:20:37.208 /reggie/dispatch 200 232ms 452cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 2011-02-25 12:19:28.348 /reggie/dispatch 200 6380ms 4600cpu_ms 190api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 2011-02-25 10:47:19.700 /reggie/dispatch 200 171ms 452cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.2.13) Gecko/20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:47:15.865 /reggie/dispatch 200 141ms 405cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.2.13) Gecko/20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:47:15.731 /reggie/dispatch 200 385ms 475cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv: 1.9.2.13) Gecko/20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:46:52.893 /reggie/dispatch 200 37ms 140cpu_ms 0kb Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/ 20101203 Firefox/3.6.13,gzip(gfe) 2011-02-25 10:37:15.031 /reggie/dispatch 200 177ms 522cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) 2011-02-25 10:36:48.890 /reggie/dispatch 200 3550ms 732cpu_ms 125api_cpu_ms 6kb Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en- US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3,gzip(gfe) Which is honestly much better then the past couple of days where saw some times over 3ms.

Re: [google-appengine] Good heavens: appengine selects primary/secondary composite index sorts on an alphabetic basis
I would suggest any debutante interested in how the datastore to watch some of the Google IO videos related to App Engine. You should also read all of the articles related to the datastore. The 'datastore' is not BigTable; it is a layer implemented on top of BigTable. You might find the discussions on merge-joins interesting. Regarding the sort-order, my statement probably lacked verbosity and clarity. Read up on how the datastore handles composite indexes. They are stored, more-or-less, as I mentioned. So, the 'final property' in the index will determine the 'initial' sort order. Also, it is the only property you can do a range-scan on using indexes. If you read some of the docs and articles and watch some of the IO video's, you'll have a much better understanding of how App Engine's indexes work. I'm not 100% sure what you mean by not being able to parallelize with a composite index. If you want to work on the dataset in parallel, start workers at different points in the composite index. Using composite indexes saves the step of combining the results from multiple indexes in-code.

Re: [google-appengine] Serving old static files when changing default version
Google cache buster. Barry's suggestion to include a version number in the static asset URLs is a common solution and good approach if you've got (or can get) a build system in place. Even some simple bash-scripting can achieve this. Robert On Sun, Feb 27, 2011 at 02:23, Varunkumar Nagarajan wrote: > I am also facing the static content facing problems recently.

Re: [google-appengine] App upload failure rate
Hey Tom, I'm on comcast (between Indianapolis and Chicago), recently (maybe the past few weeks) my internet has been flaky too. I think a part of my issue is DNS, I've added Google's Public DNS as a backup server (http://code.google.com/speed/public-dns/docs/intro.html) to my DHCP server. Helped me a bunch.

[google-appengine] sending email with GAE copies admin -- how to stop
Hello, I'm creating an app to allow people to vote in elections and this involves sending an email to each voter. I do this in a loop: mail.send_mail(sender = manager.email(), to = email, subject = election.title, body = body) where manger is the signed-in user. This appears to BCC the manager on all emails, but I don't want that to happen. Is there a way to send the email only to the intended recipient?

[google-appengine] App upload failure rate
We use Comcast as our internet connection provider and usually we need upload 4 times ( in 10 mins ) to finish a 30 files update. I guess Comcast check the pattern of the packet and freeze the connection when "necessary". ( The modern light will be off ). This also happens to skype sometime.

[google-appengine] Re: memcache weirdness since last update
I have had a problems hitting the 10second timeout on putting to the datastore which when backed up blocking on every datastore call (get or put) eventually leads to the 30second request timeout. I suppose it's possible for the cache to get out of sync like that.

No. Google is unlikely to support Microsoft Development Language in the "near" (next 50 years) term.
