cloudfoundry mysql更新不起作用

I have a grails app deployed on cloudfoundry with mysql db. The updates into the tables are flaky - when I change values it works sometimes and it doesn't work most of the times. There are no errors. It looks as if updates are going into a different db. I looked up vmc services and there is only one db associated with the application.I have a grails app deployed on cloudfoundry wi
