As far as I know, dictionary_obj_type is one of TABLE|SEQUENCE|PROCEDURE|INDEX|FUNCTION|TYPE|PACKAGE
And dictionary_obj_name is just the name of the table/sequence/proc/etc.
- dictionary_obj_type Returns the type of the dictionary object on which the DDL operation that fired the trigger occurred.
- dictionary_obj_name Returns the name of the dictionary object on which the DDL operation that fired the trigger occurred.
