ORA-28444
        cannot enforce encryption of dictionary data
        
        
        Cause
        Either encryption of the dictionary data was already enforced or an attempt was made to enforce encryption of the dictionary data with compatible parameter earlier than release 12.2.0.2.
        Action
        Ensure that the compatible parameter is later than release 12.2.0.2 because earlier versions cannot handle encrypted dictionary data.
