There are none.
One common source for performance problems is ANALYZEing the data
dictionary. You shouldn't do that.
The dictionary has been designed using the rule-based optimizer. Try
deleting the statistics (it won't harm when they are not there) by issuing
dbms_utility.analyze_schema('SYS','DELETE')
