Since, AdBreakStatus is linked to AdBreak , I am expecting a migration for AdBreakStatus also. Is my understanding wrong? Edit In the initial state, there was only AdBreak and BaseClass1 model. The

问题 We are migrating an Application consisting of several ear files from Weblogic 11 to Weblogic 12. Three of the ear files are running well, when we deploy the 4th it throws a ClassNotFoundException on startup. Two of the three running ears aren’t important in this regard. So, the situation is that A.ear runs fine, B.ear fails to start.

问题 I'm trying to migrate a mercurial repository to git, but the problem is that the mercurial repository has subrepositories (some with branches), and lots of merges and branches itself.

Error SQL71564: Error validating element [develop]: The element [develop] has been orphaned from its login and cannot be deployed. (Microsoft.SqlServer.Dac) I'm a little confused, since 'develop' is the user name we have been using for testing, nothing more, nothing less. Background: The current DB is running on SQL 2016
