You need to check the result's RC to see if it successfully submitted the PROCESS START request like the example I sent you is doing:
STAFResultPtr res = handlePtr->submit(machine, "PROCESS", request);
if (res->rc != kSTAFOk)
{
cout << "STAF " << machine << " PROCESS " << request << " failed with
RC="
<< STAFString(res->rc)
<< " Result=" << res->result << endl;
return res->rc;
}
cout << "Result (the STAF handle for the process): " << res->result <<
endl << endl;
If the process starts but then fails, then you may want to put the
process's stdout/stderr in a file so that you can see what the process is
doing and if it is logging an error message. You can do this by adding
options like " STDOUT /tmp/process.out STDERRTOSTDOUT" to the PROCESS
START request.
You should probably first simply submit the PROCESS START request via the
STAF command line executable (instead of via a C++ program) to make sure
it is working. For example:
STAF cyclvm10.rtp.netapp.com PROCESS START SHELL COMMAND
"/u/hardikd/p4/proj/hammerChange/hammer
/u/hardikd/p4/proj/hammerChange/logs -filercore hardikd-vsim2 -runtime 60
-bg" STDOUT /tmp/process.out STDERRTOSTDOUT
You can see if the process is still running by querying the process's
handle. For example:
STAF cyclym10.rtp.netapp.com PROCESS QUERY HANDLE <processHandle>
Note that a PROCESS START request requires trust level 5 so be sure that
machine cyclym10.rtp.netapp.com gives trust level 5 to the machine that is
submitting the PROCESS START request.

Subject: [staf-users] Regarding Process Start Command
Hi,
The following is my code. I wish to start a process remotely and acquire
it’s handle so I can communicate through this handle and send messages to
the process’ queue.
28 STAFString command = "/u/hardikd/p4/proj/hammerChange/hammer
/u/hardikd/p4/proj/hammerChange/logs -filercore hardikd-vsim2 -runtime 60
-bg";
29 STAFString request = "START SHELL COMMAND " +
STAFHandle::wrapData(command);
30 cout << request << endl;
31 STAFResultPtr result_hammer_start =
handle->submit("cyclvm10.rtp.netapp.com", "PROCESS", request);
32 STAFString hammer_handle = result_hammer_start->result;
It doesn’t seem to launch the Process :: the process doesn’t show up when
I do >>ps ux.
Thanks,
Hardik.
