i follow the following blog to enable the extended data types in oracle 12c
https://oracle-base.com/articles/12c/extended-data-types-12cR1
everything was okay, the logs as in the last few lines of the above blog, contains no error .
when i login to my apex account, its do the login, but have the following error
ORA-04061: existing state of package body "APEX_050000.WWV_FLOW_4000_UI" has been invalidated ORA-04065: not executed, altered or dropped package body "APEX_050000.WWV_FLOW_4000_UI"
