Fixing the Configuration after making changes to the database
If you are given a warning when you attempt to open your configuration file, it is possible that you have made changes to the database that affect the database model in the Types page. This means that the configuration file has become invalid, because some of the fields and/or tables modeled in iBridge Designer can no longer be recognized.
In this situation, if you simply refresh the database (as described in Refreshing the database information), the types affected by the database changes will be deleted as they are no longer valid. To stop types that you have created from being deleted, you must use the Configuration Fixer tool, to repair the invalid types.
After saving the changes to the configuration, the database should be opened and re-issued, for the changes to take effect.
