Get notification about invalid views

I have 40 views that are integrated/synced to a work order management system on a weekly basis. The views are based on GIS tables which are *notoriously messy*. Over time, the views can end up becoming **invalid**. Example: - A user deletes or renames a column in an underlying table, but fails to notify I.T. of the change, so the view is not updated accordingly. - As a result, the view would become invalid: ORA-04063: view "ROADS_VW" has errors or ORA-00904: "FIELD1": invalid identifier. -------- I would like to catch & fix invalid views (or fix the underlying data) before the views are synced to the work order management system each week. **Is there a way to get Oracle to notify me about invalid views?** For instance, if the integrations occur on Fridays, then get an email on Thursdays if any of the views are invalid.
