Also, I wanted to make sure that you were aware of a couple of STAX service requests that you might be interested in using from your Python program to log messages in the STAX Job User Log and to send a message to the STAX Monitor's Messages panel. To use them, you only need to know the STAXJobID (which you could make available to the Python process via a STAF variable) and the STAX service name. The STAX LOG and SEND requests are documented in the STAX User's Guide at http://staf.sourceforge.net/current/STAX/staxug.html#Header_Log.

LOG JOB <Job ID> MESSAGE <Message> [LEVEL <Level>] [SEND]
SEND JOB <Job ID> MESSAGE <Message>
LOG allows you to log a message in the STAX Job User Log for a job that is
currently running. It also allows you to optionally send a message to the
STAX Monitor. It performs basically the same action as a <log> element (or
<log message="1"> element) contained in a job's XML file.
This request is useful if you want a process defined by a <process>
element in a job to log one or more messages in the STAX Job User Log and,
optionally, to send the message(s) to the STAX Monitor to be displayed in
the "Message" panel when monitoring the job. This can be done by passing
the value of the STAXJobID Python variable to the process (e.g. via the
<parms> element or <env> element) so it can be used for the value of the
JOB option and then submitting a LOG request from within the process.
Syntax
LOG JOB <Job ID> MESSAGE <Message> [LEVEL <Level>] [SEND]
JOB specifies the ID of the job.
MESSAGE specifies the message text to be logged in the STAX Job User Log
and, optionally, sent to the STAX Monitor.
LEVEL specifies the is the logging level of the message to be logged. It
must be one of the STAF logging levels (e.g. Fatal, Error, Warning, Info,
Trace, Trace2, Trace3, Debug, Debug2, Debug3, Start, Stop, Pass, Fail,
Status, User1, User2, User3, User4, User5, User6, User7, or User8). It is
not case-sensitive. It is optional and defaults to Info.
SEND specifies to also send the message to the STAX Monitor. It is
optional.
Note that a message logged in the STAX Job User Log is persistent, unlike
a message sent to the STAX Monitor which is only displayed if the job is
currently being monitored by the STAX Monitor running on any machine(s).
Security
This request requires at least trust level 3.
Results
Upon successful return, the result buffer does not contain anything.
Examples
Goal: Log informational message "Running TestA on machine
client1.company.com" for the STAX Job ID contained in variable myStaxJobID
in the job's user log via a Python program.
message = 'Running TestA on machine client1.company.com'
request = 'LOG JOB %s MESSAGE "%s"' % (myStaxJobID, message)
res = handle.submit('local', 'STAX', request)
if (res.rc != 0):
print "\nError: STAF local STAX %s failed. RC: %s, Result: %s\n"
% (request, res.rc, res.result)
Goal: Log error message "Error in Step 3 of TestA running on machine
server2" for job 5 in the job's user log and send the message to the STAX
Monitor.
message = 'Error in Step 5 of TestA running on machine server2'
request = 'LOG SEND JOB %s LEVEL Error MESSAGE "%s"' % (myStaxJobID,
message)
res = handle.submit('local', 'STAX', request)
if (res.rc != 0):
print "\nError: STAF local STAX %s failed. RC: %s, Result: %s\n"
% (request, res.rc, res.result)

Re: [staf-users] Unable to use Static Handle with the consecutive commands
in a STAX job file
Well, you have a few problems in your code. First, you are starting your
Python program via your STAX job and the Python program is submitting a
VAR RESOLVE request to resolve STAF variables PY_STATIC_HANDLE and
MyTest/JobUserLogName before your STAX job has even had a chance to set
them. So, your Python program ends up writing to the previous STAX Job
User Log, not the current STAX job log.
Instead, you should set these STAF variables on your PROCESS START request
using the VAR options in your <process> element, instead of setting them
later after starting the process. For example:
<script>
stdinFile = 'C:/tests/PyInt.py'
request = 'START COMMAND python STDIN "%s"' % (stdinFile) + \
' VAR PY_STATIC_HANDLE=%s VAR MyTest/JobUserLogName=%s' %
(staticHandleNumber, STAXJobUserLogName)
</script>
<stafcmd>
<location>'local'</location>
<service>'PROCESS'</service>
<request>request</request>
</stafcmd>
And remove the following code:
<!-- Inform Python about this static handle by setting a STAF env.
variable -->
<stafcmd name="'Set STAF ENV var'">
<location>'local'</location>
<service>'VAR'</service>
<request>'SET SHARED VAR PY_STATIC_HANDLE=%s VAR
MyTest/JobUserLogName=%s'\
%(staticHandleNumber, STAXJobUserLogName)</request>
<stafcmd>
<if expr="RC == 0">
<log>'Handle shared'</log>
<else>
<log>'Could not share handle, RC = %s, STAFResult =f %s' %(RC,
STAFResult)</log>
</else>
</if>
Also, you're not specifying the right request to log to the STAX Job User
Log. The STAX Job User Log is a STAF machine log, not a handle log, so
when logging to it you need to submit a request to the LOG service like
the following (assuming variable myStaxJobUserLogName contains the correct
log name for the STAX Job User log). You should also verify that the log
request worked. For example:
message = 'Testing 123'
request = 'LOG MACHINE LOGNAME %s LEVEL Info MESSAGE %s' %
(myStaxJobUserLogName, message)
print '\nSTAF local LOG %s' % (request)
result = handle.submit('local', 'LOG', request)
if (result.rc != 0):
print '\nSTAF local LOG %s failed, RC: %s, Result: %s\n' % (request,
result.rc, result.result)
Or, when using the STAFLog class, you need to specify that it's a machine
log (not a handle log) and you need to specify the proper name for the
STAX Job User log. For example:
Log = STAFLog(handle, STAFLog.Machine, myStaxJobUserLogName)
message = 'Testing 123'
print '\nLog message %s to log %s' % (message, myStaxJobUserLogName)
result = Log.log(STAFLog.Start, message)
if (result.rc != 0):
print '\nLogging to %s failed, RC: %s, Result: %s\n' %
(myStaxJobUserLogName, result.rc, result.result)
With these changes, the Python program was able to log messages to the
appropriate STAX Job User Log and I was able to view them.

Re: [staf-users] Unable to use Static Handle with the consecutive commands
in a STAX job file
Guys,
With the above approach, I found that I'm unable to log Monitor or Log
messages from my Python programs. I used STAFMon and STAFLog to these and
have tried sending these messages using the Static Handle and the handle
of Python program.
Just to refresh, I used static handle to queue messsages between stax job
and python program.
It seems to me that the code in xml where I'm actually waiting for queue
messages is stopping the monitor and log messages from displaying in the
STAX monitor window.
Here is the code snippet:
The STAX xml job:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">
<stax>
<defaultcall function="startHere"></defaultcall>
<script>
from com.ibm.staf import *
STAXMessageLog = 1
STAXLogMessage = 1
handle3 = STAFHandle("MyApplication")
result = handle3.submit2("local", "HANDLE", "CREATE HANDLE NAME
MyStaticHandle")
staticHandleNumber = int(result.result)
staticHandle = STAFHandle(staticHandleNumber)
</script>
<function name="startHere">
<sequence>
<stafcmd>
<location>'local'</location>
<service>'PROCESS'</service>
<request>
'START COMMAND python STDIN

</request>
</stafcmd>
<if expr="RC == 0">
<script>handle2 = STAFResult</script>
<!--<log>handle.handle</log>-->
<!--<log>handle</log>-->
<else>
<log>'RC = %s, STAFResult = %s' %(RC,
STAFResult)</log>
</else>
</if>
<log>'handle2 = %s' %(handle2)</log>
<!-- Inform Python about this static handle by setting a STAF
env. variable -->
<stafcmd name="'Set STAF ENV var'">
<location>'local'</location>
<service>'VAR'</service>
<request>'SET SHARED VAR PY_STATIC_HANDLE=%s VAR
MyTest/JobUserLogName=%s'\
%(staticHandleNumber,
STAXJobUserLogName)</request>
</stafcmd>
<if expr="RC == 0">
<log>'Handle shared'</log>
<else>
<log>'Could not share handle, RC = %s, STAFResult =f

<log message="1">

</log>
<log message="1">
'RESPONSE received: %s' % (queueMsgMap['message'])
</log>

</if>
<!-- ************ Queue BootSigGen REQUEST ************ -->
<script>
#submit STAF Queue message request
result1 = staticHandle.submit2("local", "queue", "QUEUE

</script>
<if expr="result1.rc == STAFRC.Ok">
