If your session actually performed OS read calls of rollback segment
blocks, then in your trace data (level 8 or level 12; that is, with
<waits=true>) you'll be able to see your rollback segment block accesses
from the p1  (file id) and p2 (block id) values associated with WAIT
lines whose <nam> has the value <db file sequential read>.
