When the database is disconnected by exception, the Web application stops working. Closing and re-opening the application does not fix the problem.
Cause: When the database is disconnected by exception, the status of the data source to the database remains connected in EAServer. When the application is restarted, EAServer will not try to reconnect the database.
Solution: Any of the following operations should resolve the problem.
1. Restart EAServer
2. Refresh the relevant data source using EAServer Manager
