Is there any way to count the actual number of users current logged in to the applications?
if you are talking about database then run below query u will get result
SELECT s.osuser, p.spid
|| ' '
|| DECODE (s.machine,
NULL, 'Lan:',
s.machine || ':'
)
|| s.osuser
|| '<'
|| DECODE (s.terminal, NULL, 'Batch/Det', s.terminal)
|| '>'
|| DECODE (s.username, s.osuser, NULL, s.username) IDEN,
DECODE (s.command,

FROM v$session s, v$process p
WHERE s.TYPE <> 'BACKGROUND' AND s.paddr = p.addr ORDER BY s.osuser
/
as far as application concern
application use application user name not database schema name so the session open between apps and db tier is by database username u cant get currently connected user from application to DB.
