10 years ago I had a problem on my AIX's with rexx if I had several rexx
The problem was that tne rexx's "snatch" data from each others rxqueue.
I think we at that time used rexx version 1 or 2.
Because of this I added following to my rexx's
/ define rexx queue /
newq = rxqueue('c')
oldq = rxqueue('s',newq)
/ the work to be done /
'hostname | rxqueue ' newq
/ del tmp queue /
rx = rxqueue('s',oldq)
ry = rxqueue('d',newq)
I have not been able to recreate the problem using oorexx 3.2 or oorexx 4.1)
Can anyone tell me it this is still needed ?
It largely depends on how you are invoking the rexx programs. Each rexx
process will create a private session queue for that process so it is a
private queue. This also sets an environment variable for the process that
will be inherited by child processes such as the rxqueue filter so they can
determine which session queue to use. So, if you have a single top-level rexx
program that starts a bunch of background processes, then each process will
inherit the environment variables of the parent process and use the same
session queue. If you are launching these programs as separate top-level rexx
programs, then each one will use a different session queue and they will not
interfere with each other.
Thanks, good explanation and this explains the situation :-)
