Hi David,
Thanks for the response. I now have a followup question again about queues.
This is my scenario. I launch 4 processes in async mode with notify onend
option using process service. Then I run staf local queue get wait <timeout>
But immediately after that I launch 4 other processes in async mode with
notfiy onend option using process service. Then I run staf local queue get wait
<anothertimout>
How do I ensure that process launched in the second set not end up
getting into first queue.
Thanks,
Arvind
