If there is an entry in V$SESSION, does it imply that user has a current session within the instance?

If not, how do I determine which users have logged out of the DB?

Under what conditions would I not be able to obtain any SQL from V$SQLAREA for any given SID?

1 select username, osuser, sql_text
2 from v$session ss, v$sqlarea sa

  3  where ss.sid = 861
  4   and  ss.sql_address = sa.address
  5*  and  ss.sql_hash_value = sa.hash_value

bcm_at_MWH.ARES.MWH.COM> /

no rows selected

bcm_at_MWH.ARES.MWH.COM> select * from v$session where sid = 861;
