Oracle 9iAS in Apatch

1. I have web-based system with Oracle Forms to develop and running in Oracle 9i AS under Apatch ennvironmnet. Username and password will be asked when user login to the system.
2. The problem is that in the Apatch log file the I can see jsession id only, but NOT the username in each access record. Can you please tell me how!??

Thanks 🙂
