This one is easy: look in v$waitstat. That has the class numbers for all block classes. Then add to that the undo segments. Each undo segment has two types of class. A undo header class and undo block class. So by looking at v$waitstat you should be able to tell that 36 is a undo block that belongs to rollback segment 10 or so (depending on the number of rows in v$waitstat).
