object_name for p1,p2 from ash report.

How to find the object_name,object_type for this values in ASH report.

eg:-

select
  segment_name,
  segment_type
from
   dba_extents
where
   file_id = 5228121616
and
   122 between 
   block_id and block_id + blocks – 1;

This gives me no rows selected. How can i come to know what object is causing 21% latch:cache buffer chains in my database.

Pls advice.
