The problem is with the argument you are passing.  Instead of 'aristo'
you=20
need to pass it as "'aristo'" so that the quotes are not stripped from
the=20
command line (otherwise the STAX  Python interpreter will try to get the

value for a variable named aristo, instead of the literal string=20
'aristo').  I get the same reults as you if I don't have the additional=20
quotes:

Re: [staf-users] Return value from STAX file

My code is same.. but Im confused where the problem is.

<function name=3D"FindOS">
      <function-prolog>
         Function to Identified the OS of the system provided as
argument. This function
         basically sets a global variable called opSys to whatever the
uname output.
     </function-prolog>
      <function-single-arg>
        <function-required-arg name=3D"Targetsys"/>
      </function-single-arg>
    <sequence>
        <stafcmd name=3D"'FindOSType'">
           <location>Targetsys</location>
           <service>'var'</service>
           <request>'resolve system string
{STAF/Config/OS/Name}'</request>
        </stafcmd>
        <return>STAFResult</return>
    </sequence>
   </function>

Im calling it like .

[root@spartan stax]# staf local stax execute file `pwd`/test.xml
function FindOS ARGS 'aristo' WAIT RETURNRESULT
Response
--------
Job ID: 75
Result: None

But I'm getting the result properly when I use <message> and see it in
STAXMon, or if I use <call> and get the result via STAXResult.

Using <return> in a non-defaulf function also works correctly for me:

  <function name=3D"test2">

Re: [staf-users] Return value from STAX file

David,

You are right. When I embed the machine name and the defaultcall
function (findOS) in the STAX file, it is returning correctly, But my
STAF cmd line is calling a function in the file directly with Argument
as Machinename. In that case, why its not returning... any Idea.=20

STAF local stax execute file `pwd`/test.xml WAIT RETURNRESULT

Response
--------
Job ID: 54
Result: Linux

But I want=20

STAF local stax execute file `pwd`/test.xml Function FindOS ARGS
'aristo' WAIT RETURNRESULT.

Are you sure the <return> is in the starting function of your STAX job?

Subject: Re: [staf-users] STAX monitor events
=20

To get the messages for each STAX job that your custom tool executes,
you=20
would need to submit a REGISTER request to the Event service for each
STAX=20
job executed for TYPE "STAX/<STAXMachineName>/<JobID>" and for SUBTYPE=20
Message.  For example:=20

STAF <EventMachine> EVENT REGISTER TYPE "STAX/<STAXMachine>/<JobID>"=20
SUBTYPE "Message"=20

(replacing <EventMachine>, <STAXMachine>, and <JobID> with the correct=20
values, and assuming STAX is the registered name of your STAX service
and=20
EVENT is the registered name of your event service)=20

The STAX Monitor does this via the startMonitor() method in=20
services/stax/monitor/STAXMonitorFrame.java (it it registers for other=20
subtypes too like Process, STAFCommand, Testcase, TestcaseStatus, Job,=20
etc.  For example, here's the specific line in the startMonitor()
method:=20

STAFResult registerResult =3D fHandle.submit2(=20
    fEventMachine, fEventServiceName,=20
    "REGISTER TYPE " + fStaxServiceName.toUpperCase() + "/" +=20
    fStaxConfigMachine + "/" + fJobNumber +=20
    " SUBTYPE Job SUBTYPE Block SUBTYPE Process " +=20
    "SUBTYPE STAFCommand SUBTYPE Message " +=20
    "SUBTYPE Testcase " + "SUBTYPE TestCaseStatus " +=20
    "SUBTYPE subjob " + externalSubTypes.toString() +=20
    " MAXATTEMPTS 1 ACKNOWLEDGETIMEOUT 1000 BYHANDLE");=20

Note that you might miss some messages that are generated at the
beginning=20
of a STAX job while you're registering, which is why the STAX Monitor=20
submits a STAX EXECUTE request using the HOLD option so that it holds
the=20
job until it's registered with the Event service for info about the STAX

job and then submits a STAX RELEASE request to release the job.=20

Once your custom tool has registered with the Event service to be
notified=20
(as shown above), the Event service will notify your custom tool that an

event has occurred by queueing a message with queue type=20
"STAF/Service/Event".  So, your custom tool would also need to have a=20
thread that submits a "GET WAIT" request to the QUEUE service in a=20
continuous loop to get the messages that it registered for.  See the
run()=20
method in services/stax/monitor/STAXMonitor.java.  Read the Event
Service=20
User's Guide for more information at=20
http://staf.sourceforge.net/current/event.htm.  And read about the
"Queue=20
Service" in the STAF User's Guide at=20
http://staf.sourceforge.net/current/STAFUG.htm#HDRQUEUESRV.=20

As an easier alternative, you could make sure that your STAX jobs also=20
logged any <message> elements (e.g. by either doing <message log=3D"1"> =
or

by setting the STAXLogMessage variable to 1), as any messages that are=20
important should be logged since messages sent via a <message> element
are=20
not persistent (e.g. if no one is registered for the particular STAX
job's=20
messages, then the messages are "lost").  Then you can obtain any
messages=20
logged in the STAX Job User logs by submitting QUERY requests to the LOG

service.  For example, to query the STAX Job User log for Job ID 1 on
stax=20
machine server1, you could run:  STAF server1 LOG QUERY MACHINE=20
{STAF/Config/MachineNickname} LOGNAME STAX_Job_1_User.

[staf-users] STAX monitor events
=20

=20
=20

Hello,

I've spent some time today looking for a way to listen to the messages=20
that=20
come from the stax service. (<message> blocks in the STAX script). The=20
STAX=20
Monitor can show these live, and I found some similar questions on the=20
list=20
already. Although there answers hinted to the Event and Queue services,=20
I'm=20
still stuck.

The point is that I launch my STAX jobs from a custom made tool and I
want=20

to get feedback while the job is executing. I didn't find any type in
the=20
event service that might be used by STAX to send its messages to the=20
monitor.

I quickly scanned through the STAX source code also, but i don't find my

way=20
there very well. I didn't found what i was looking for yet. Does anyone=20
have=20
an idea what event types I should listen for?

thanks.
