"object %s.%s of type %s exists"
*Cause: 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.
*Action: 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.
