When distributing the application, the configuration files are instead shared via a local datastore or the central database. The local datastore or the central database, stores the same local filesystem configuration directory structure in dedicated SQL tables, each table containing different configuration directory. The configuration in the central database belongs to a dedicated Delft-FEWS implementation of a particular forecasting system. In the live system situation the contents of the database will be shared between all operator clients and forecasting shell servers in the system, and is therefore expected to be identical in all parts of the system. In the central database active versions of configuration items have synchLevel 11 whereas inactive configuration files have synchLevel 0. The ConfigRevisionSets table defines the the active configuration.

When initiating the Delft-FEWS application, it will look for configuration stored in the local datastore or in the filesystem. If both are found, then the system might ask the user to choose which to use. If neither is found then an appropriate error message is issued and the system will stop. |
