Oracle Database Discussions

Hi,

We have a multithreaded application and each thread connects to database using the same userID.
How do I identify on the dtabase side which DB connection belongs to which client thread?

I need to uniquely map the client processID:Thread ID to a DB connection.
On Unix I do not see the processID:Thread ID pair in the v$session table process column.
It is only showing the PID.

Any other ways to map the client PID:TID to db connection?

Thanks
