Find thread that opened a session in AIX

Question

Hello.
As stated in "Determining which Oracle database session is being used by a specific Siebel user session [ID 863771.1]":
On the Oracle database side, you can query the V$SESSION table (make sure you are logged in as the tableowner) using the following WHERE clause format:
WHERE PROCESS='XXXX:YYYY'
XXXX = Server PID
YYYY = Thread ID
So querying v$session, sessions opened by windows clients have in the PROCESS column values like "12345:876", where 12345=process id and 876=thread id.
Our application servers are installed in AIX, which is also multithreaded, but in the PROCESS column only process id is stored.
Is there any way to find thread id?

I see.
V$SESSION.PROCESS is does not look reliable source of Thread
- I've connected to Oracle in Linux from Windows SQL*Developer - V$SESSION.PROCESS shows 1234, though in Windows the SQLDeveloper PID is 6896 and some thread has opened the connection.
- I've connected to Oracle in Windows from same Windows SQL*Developer - V$SESSION.PROCESS shows 6896 but no thread.
May be there is something in V$SESSION.MODULE, ACTION or CLIENT_INFO that may identify a client thread? (It is application who should populate these columns)
Or you can use V$SESSION.LOGON_TIME and according col in SIEBEL.S_SRM_TASK_HIST.
Also, if your Siebel uses LDAP, may be it uses it for proxy authentication?
In this case you can look into v$session_connect_info to see actual user.
There are some date columns in SIEBEL.S_SRM_TASK_HIST, but none of them match exactly V$SESSION.LOGON_TIME.
I would have to start guessing between 2-3 sessions which one is the correct, since there are +500 conc. users, but perhaps this is the only way to do something, at least.
I've seen v$session_connect_info, but it doesn't help.
select a.*
from v$session_connect_info a, v$session b
where username='SIEBELUSR'
and a.sid=b.sid
and a.serial#=b.serial#;
