Enter a timestamp that is one year ago for the Last Access Time and then click Go. A list of segments that have not been accessed or modified in the last year are displayed. The segments are sorted in descending order by segment size.

On the object level heat map, you can search for a specific segment based on Tablespace, Name, Partition, Type, Last Access Time, Last Write Time, Last Full Scan Time, and Last Look Up Scan Time.

You can select a row (segment) and view the row activity for that segment clicking the Policies column to view the policies associated with the segment.
