I don't understand why you have to have one process open a file and having
other 2 processes access the same file descriptor.
Can you try something like :
<script>
filename = '/tmp/testdata.txt'
</script>
<stafcmd>
<location>'local'</location>
<service>'VAR'</service>
<request>'SET SHARED VAR TEST_DATA_FILE=%s' % (filename)
</request>
</stafcmd>
When you need access the file
<stafcmd>
<location>'local'</location>
<service>'VAR'</service>
<request>'GET SHARED VAR TEST_DATA_FILE'</request>
</stafcmd>
<script>
filename = STAFResult
buffer = 'test strings...'
FILE = open(filename,"a")
FILE.write(buffer)
FILE.close()
</script>

Subject: Re: [staf-users] STAX script query
Hi ,
Actually what I need is that for example, I have 3 STAX scripts.
Now if I open a file in one of the main scripts and then using that file
object need to write some data in the file in the other two scripts and
finally close the file in the main script.
Also, I can't open and close the file again nd again as the processes
defined in other scripts are running in paraalel which is the main
problem.
Can this be done??
Thanks

What is the use case for sharing the file python object? Note that you
can share the 'filepath' in many ways. A simple way is to use STAF VAR
service.
Perhaps you can try using STAXGlobal class, see
http://staf.sourceforge.net/current/STAX/staxug.html
STAX-Threads
When the STAX Service executes elements in parallel, rather than using
real system threads (and thereby potentially creating an overabundance of
system threads), the STAX Service will simulate the threading capabilities
via a thread pool which will utilize a manageable number of real system
threads. These simulated threads are called STAX-Threads.
Whenever a new STAX-Thread is created, existing variables are cloned from
the parent STAX-Thread. To create a global variable that can be accessed
across STAX-Threads, use the STAXGlobal class described in "STAXGlobal
Class" section. STAX elements that can create STAX-Threads include the
following: <parallel>, <paralleliterate>, <process-action>, <job-action>,
and <function> elements with a local scope.

Subject: Re: [staf-users] STAX script query
hi,
is there any way to share file objects in STAF in differen files using the
environment variable functionality.
E.g. File = open( filepath, 'w')
i want to share the '' File '' object over the system, can it be done as I
am only aware about sharing strings.
Thanks
