I am trying to delete a column from one of the tables in physical layer. In 11g, when a column is deleted, it used to delete in the related aliases as well. I am on version 12.2.1.2.0 now and deleting a column in the physical table will not delete it in the alias anymore. It changes the icon to a yellow warning triangle in the alias.
when i try to hover over the mouse to select it, the Admin tool goes not responding and gets killed.
did anyone observe the same issues?
