Multiple R47011 Jobs Simultaneously

Active Member
Assuming no CPU/disk/database bottlenecks, what are thoughts/concerns on
running multiple R47011 jobs simultaneously, each with a different data
selection to increase total throughput of sales order lines?

Thanks,

My experience is that the overall throughput increases while individual v=
ersion throughput decreases. =20

It will be interesting to see how much of a bottleneck the JDE application
is but we are running this on a very powerful system. The commit rate is
high with all JDE jobs so Oracle writing to the logs (LGWR) is going to be
the bottleneck. If we can clear that up and increase the number of
processes that can access the key tables simultaneously for
update/insert/delete activity I think we can greatly increase the overall
speed of the job. Our primary concern is that the jobs will "behave" nicely
when run simultaneously. - E

As far as your concern, multiple R47011 jobs can behave nicely when runn=
ing simultaneously according to my experience (I have more than 20 jobs).

Here is a precaution. Every job (version) should have its own data select=
ion. And if you are using more than one server, submit the same version t=
o ONLY one server. Or you may experience unpredictable results. For insta=
nce, duplicate records or jobs get killed because of dead locks.

Hopefully it helps. It's highly appreciated if you can share some of your=
performance statistics with me later on.

are all 20 running at the same time? have you really set up 20 queues to
handle so many concurrent jobs? if not, how many have you actually run
concurrently with success?

Yes, all are running at the same time across three application servers. E=
very app server has 10 single-threaded queues and 1 multi-threaded queue.=
