Re: Number of threads is twice the number of sessions with 10.2 on Windows platform

I did some additional tests here are the results
1) if you connect as sysdba you get only 1 thread
2) I launched a Java program  which opens 100 db concurrent
connections and keeps them open for 20 minutes. For all the duration
of the test the thread number was 227, when the program ended the the
number drop to 27
So at least to me the results seem consistents. In the afternoon I
will try to exit from the program without closing the connection in
oder to see if there is some recovery mechanism.
