Oracle Error Message
ORA-23309: object string.string of type string exists
Reason for the Error
An object in the same namespace exists, perhaps with a different type or shape, or the same object has already been registered as an repobject in another object group.
Solution
Remove the offending object with the SQL DROP command, unregister the offending object with dbms_repcat.drop_master_repobject(), or reinvoke the request using TRUE for a boolean parameter such as retry or use_existing_object.
