[appengine-java] URGENT: Upcoming scheduled maintenance: 2011 Jul 14
(If your application uses High Replication datastore, you can ignore this email) Attention App Engine users! We have an urgent scheduled maintenance period coming up *this* Thursday, 2011 Jul 14th. We apologize for the shorter-than-usual notice and will work hard to make sure that more lead-time is given for future downtime periods. The maintenance period will last approximately one hour starting exactly at this time: Thursday, 2011 Jul 14, 5:00pm/1700 PDT/GMT-7 (Friday, 2011 Jul 15, midnight//GMT) Note that this downtime does *not* affect High Replication datastore users as far as service goes, but neither Master/Slave nor HR datastore apps will be able to deploy during this period. Below is the standard information we usually send out with these notifications. Check it out for more information about read-only periods or how to be notified of production events. -- The Master/Slave datastore will be placed into read-only mode and memcache will be flushed. It is recommended that critical portions of your application that depend on the datastore should make use of the capabilities API to detect and recover gracefully during read-only periods. Documentation describing the capabilities API can be found here: - Python: http://code.google.com/appengine/docs/python/howto/maintenance.html - Java: http://code.google.com/appengine/docs/java/howto/maintenance.html There will be no downtime for developers whose applications use High Replication datastore. You can read more about High Replication here: http://googleappengine.blogspot.com/2011/01/announcing-high-replication-datastore.html Developers can subscribe to the scheduled maintenance calendar using the following link: https://www.google.com/calendar/b/0/embed?src=4chlpo92ci2f54c2u21shbj...@group.calendar.google.com Developers can add/view the scheduled maintenance calendar using this address (look for the + in the corner to subscribe to this calendar): 4chlpo92ci2f54c2u21shbj...@group.calendar.google.com Keep an eye out on this thread for more announcements regarding the downtime period.

[appengine-java] Re: 500 Internal Server Error:Unable to update app: Error posting to URL: https://appengine.google.com/api/appversion/clonefiles?
we are continually working on improving the overall reliability, but on some occasions, the system will experience higher than normal latencies within the underlying infrastructure, which may manifest itself to users in the form of upload issues, timeouts (DeadlineExceeded), or other server 500 errors. for this particular situation this Saturday morning Dec 17, the problems seem to have began around 8a PST but have all been resolve by 10a. your performance should have returned back to normal levels. we apologize for the convenience you experienced during this time. if you encounter a similar situation, pls post to the forums or create a production ticket(*) as you have been doing, esp. with any error screen captures, and your app ID, so that those of us who help monitor the system can contact the oncall team -- chances are, the team is already aware of the problem and are working to resolve it as quickly as possible -- we want to be down as much as you do... which is not at all. (*) -- to create a production ticket, go to: http://code.google.com/p/googleappengine/issues/entry and select Production issue from the Template pull down and give as much info as possible. best regards, -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Core Python Programming, Prentice Hall, (c)2007,2001 Python Fundamentals, Prentice Hall, (c)2009 http://corepython.com wesley.chun : wesc+api at google.com : @wescpy developer relations :: google app engine @app_engine :: googleappengine.blogspot.com -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Error in Production Datastore Explorer
david, thanks for writing back. i wasn't around during the time when they designed this core part of App Engine's data models, but one obvious thing that stands out in my mind as a good reason is the validation of these special fields. if you had automated checks of this data, you would, presumably need some string that represents a valid URI. other reasons include consistency to the gData interface as well as the equivalent data in XML or Atom formats. if you want to allow blanks, it may be better to just leave them as StringProperty. -- wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Core Python Programming, Prentice Hall, (c)2007,2001 Python Fundamentals, Prentice Hall, (c)2009 http://corepython.com wesley.j.chun :: wesc+...@google.com developer relations :: google app engine -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
