Hello Ralph, Is there a particular reason why you need the production database to test? Where I work, our production services contain confidential data, so we generate dummy data from a script (similar to this: http://www.generatedata.com/#about ). Also it's much faster than using the Remote API.
If you need your production database, we can try something else: perhaps your db is getting corrupted because of its location. You can move the location of local_db.bin by specifying a system property: https://groups.google.com/forum/?fromgroups=#!topic/maven-gae-plugin/V3MrpRYu6oE . Try moving it entirely outside of your dev folders, see if that helps you. If not, you can always try backing up the .bin file and restoring it whenever it gets corrupted. ----------------- -Vinny P Technology & Media Advisor Chicago, IL @GOV on AppDotNet: https://alpha.app.net/gov On Friday, April 12, 2013 3:07:15 AM UTC-5, Ralph Brecheisen wrote: > > Hi, > > I already use the approach suggested by Simon.
