Goal

The pre-configured CDC Asynchronous HOTLOG Change Source has the wrong SOURCE_DATABASE.

SQL> select source_database from change_sources where source_name = 'HOTLOG_SOURCE';
SOURCE_DATABASE
----------------------------------------------------------------------------------------------------------------------------------
BAD.WORLD

SQL> select * from global_name;
GLOBAL_NAME
----------------------------------------------------------------------------------------------------------------------------------
ORCL.WORLD
 
It cannot be altered or dropped using the DBMS_CDC_PUBLISH procedures; ALTER_HOTLOG_CHANGE_SOURCE, DROP_CHANGE_SOURCE because the ORA-31504 error would be returned.
