you'll need a space " " between the wrapped command and the ASYNC
keyword like ." ASYNC ..."
and if someone isn't manually closing notepad, you're going to have to
programmatically do it:
submit(..., "PROCESS", "STOP HANDLE $request USING WM_CLOSE");
so that it will end

I tried with following but didn't get the expected result. Is
there anything wrong I am doing?
# fill in @machines
use strict;
use Data::Dumper;
use lib qw( ... ); # Path to PLSTAF
use PLSTAF;
my $name = "test";
&STAF::Register($name);
my $requests = 0;
my $command = "notepad";
my $request = "START COMMAND ".STAF::WrapData($command)."ASYNC
RETURNSTDOUT STDERRTOSTDOUT NOTIFY ONEND KEY 100";
foreach my $machine (@machines)
{
if(STAF::Submit($machine, "PROCESS", $request) ==
$STAF::kOk)
{
$requests++;
}
}
if($requests) # I think this test may be redundent
{
for(1 .. $requests)
{
STAF::Submit("local", "QUEUE", "GET TYPE
STAF/PROCESS/END ");
my $result = $STAF::Result;
my $data;
if(STAF::STAFIsMarshalledData($result))
{
my $mc = STAF::STAFUnmarshall($result);
$data = $mc->getRootObject()->{message};
}
else
{
# take care of it
}
print Dumper($data);
# parse it out further to do real work here
}
}
After execution the result
-------------------------------------
$VAR1 = undef;
$VAR1 = undef;
$VAR1 = undef;

that actually is even easier.
in the $request, make sure to use the "ASYNC RETURNSTDOUT
STDERRTOSTDOUT NOTIFY ONEND KEY $some_unique_identifier" keywords (ok,
the *STDOUT keywords are only if you care about the output of the
process, but you can figure that part out). The return code will be
there regardless of the output though.
that way, you don't have to send it asynchronously yourself (the
Process Service will do it for you -- STAF is so Awesome)
then make your request to the QUEUE Service with something like
"GET TYPE STAF/Process/End"

I am looking more than the process submition result
here.
Suppose I submit the following request using submit2
then how to get result back that submitted process tasks has completed
on machine 1 and machine2?
$result = $handle->submit2("Machine1", "PROCESS",
$request);
$result = $handle->submit2("Machine2", "PROCESS",
$request);

use submit2
(http://staf.sourceforge.net/current/STAFPerl.htm#Header_Submit2OO) with
STAF::STAFHandle::kReqQueue
then send a Synchronous request to the QUEUE service for
the results of those requests.

Subject: [staf-users] Is there any way to track
submitted request statuscompletion with basic STAF
Hi,
I am trying to execute some process on 3
different machines from one of the driver machine. The main goal is
after completion the tasks on three different machines, I want to copy
the result file from those three machines into driver machine and
compute the result.
I am using STAF and PERL to do the basic
prototype.
My question is after submitting the task using
STAF, is there any way to check that submitted tasks has completed or
not?
Here are the following steps which I want to
achieve: I am stuck on Step 5 now.
Step 1 - Registering STAF
Step 2 - Submitting the request on Machine1
Step 3 - Submitting the request on Machine2
Step 4 - Submitting the request on Machine4
Step 5 - I want to check Step 3, 4 and 5 tasks
has completed or not ----------------------------------->? How should
I do that?
Step 6 - If completed all the tasks copy the
result file from machine 1, 2, 3 to driver machine
Can anybody please suggest me how to work it
out?
Thanks, Avi
