Hiding information is not good - and exclude_seed_cdb_view is now an underscore in Oracle 12.2I have received several questions from customers in the past weeks using Oracle Multitenant about the parameter exclude_seed_cdb_view.It magically disappeared and morphed into _exclude_seed_cdb_view since Oracle Database 12.2.0.1.

Problem
