Thanks for the reply! V$SESSION the same as V_$SESSION ? I found the latter when logging on as "sys" under Views in the Object Browser but couldn't find one without the underscore.

In any case, it shows 15 tuples all marked as "Active" under Status. I log on with my ODBC app, and a new tuple pops up showing me with a new SID, and application info it launched from, etc, but then when I log off, the tuple (and SID) does indeed disappear. My application calls SQLDisconnect() and SQLFreeHandle()
when quitting, is there something else I need to do to "close" the session?
