How to Find Client OS type from Oracle 8174......

[Janardhana Babu Donga]

Dear List,   We have TXN processing system with as many as 900 users log in at any point of time. We have the necessity to find what OS type the client is using (Windows 95, NT 2000 etc).  I tried thru V$SESSION, V$SESSION_CONNECT_INFO and V$PROCESS, but couldn't find any useful info to get the client OS type. I also looked at the NET8 documentation to see if I can get any such info. I am not successful in getting such information from any source.   Could some one help me how I should get such info.  Appreciate a reply.   -- Janardhana
