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

Hi all.

I have noticed too many threads in the Task Manager related to the ORACLE.EXE process for 10.2.

So I run a simple testcase program on a test server with no activity and I fired 10 SQLPLUS connections to the 10.2 database; the number of threads increased from 31 to 51, so 2 threads for each session connected to the
database.

Then I run the same program on the same test server directing the connections to a 9.2 database; the number of threads increased from 12 to 22, so 1
thread for each session, as expected.

Is there anybody with the same problem?

Thanks
Paolo
