Removing a dictionary schema
Removing a dictionary removes the dictionary schema and all data. When you remove a dictionary schema, all synonym lists, coding definitions, assignment rules, and requests entered against the dictionary are lost and cannot be retrieved.
Caution:
Oracle recommends that you do not remove the dictionary schema or delete a dictionary that has been used for coding. Delete only dictionaries that you have set up but have not coded against.Parent topic: Maintaining the coding dictionaries
