Yes, you could use the STAF QUEUE service's QUEUE request (e.g. via a
<stafcmd> element in a STAX job) to send "commands" to a program (e.g.
that you write in Java, Python, Perl, C/C++, or Tcl). This program would
create a STAF handle and read the commands from its queue (via a QUEUE GET
WAIT request). You can invoke this program via a <process> element in
your STAX job.

[staf-users] keeping a handle to a prevously invoked process
Hello,
I am looking for a robust way of using a STAX script to invoke a process
on a remote machine, maintain a "handle" of some sort to that process
(which I'd like to continue running in the background), and then later
have other process elements send commands to that process, returning the
output.
Specifically, I want to use STAX to connect to a remote database. On that
remote machine, other pieces of software modify the db contents. Via the
database connection that I just opened, I want to query for a particular
state, returning the output of those queries to be handled by STAX logic.
When a certain state has been reached, I want to break out of the loop and
end my database connection.
Is there a way to "resume" sending commands to some previously-started
process?
Thank you.
