Jane,
This is normal behaviour running a java application under Linux and has
nothing to do with Netview itself as per Sun's (SDN) comments below:
"Under Linux, threads are implemented using the clone() system call.
This creates a new process which can share memory space, file
descriptors and signal handlers. This means each thread which Java
creates appears as a separate process which will show up in ps. This is
normal."
You should see one master pid and several child pids depending on the
no. of threads.
Cheers

Subject: [NV-L] Reporting NetView process threads with NetView ITM agent
NetView 7.1.5 on SuSE 9 Linux.
One of the out-of-the-box views that you get with the ITM NetView Agent,
shows the number of threads per process.
I had always thought that some of the NetView processes are
multi-threaded - largely the Java based ones so, webserver, snmpserver,
servmon, maptreeserver. If you do a ps -ef listing on a SLES 9 system
then you apparently get lots of processes showing for each of these
daemons, rather than several threads, whereas on an AIX system you tend
to see a single process. Can anyone clarify this for me???
Going on from that, the ITM NetView agent is reflecting what I see in ps
- lots of processes for these daemons on a SLES 9 system. I'd much
rather see a single process with several threads. Any suggestions???
Many thanks,
Jane
