Mario

so how comes, that I am not able to find the corresponding SPID to my NT-processes ???

I tried the following statement :

############################################################################
#####################################
select
     substr(a.spid,1,5) pid,
     substr(b.sid,1,5) sid,
     substr(b.serial#,1,5) ser#,
     machine box,
     substr(b.username,1,10) username,
     -- b.server,
     substr(b.osuser,1,8) os_user,
     substr(b.program,1,30) program
     from v$session b, v$process a
     where
     b.paddr = a.addr
     and type='USER'
     order by spid;

## and I got :

PID   SID   SER#  BOX                                             USERNAME
OS_USER  PROGRAM                       
----- ----- ----- ----------------------------------------------- ----------
-------- -----------------------------
00111 58    10121 networkname                                     xx

xxxxxxx C:\myexe.exe

############################################################################
#######################################

(beware of wordwrap here)

If find the process myexe.exe on networkname in the taskmanager. It's PID is : 478 (HEX 1DE). The database is on a separate server in the network.

None of the processes, running on the client could pointed to a SPID on the server..... ???!!!!
