AW: Your experience with performance

[Becker Stephan (extern)]

Karsten,
 
if workflow is the best design solution for your problem, use it and =
live
with the technical consequences; changing the design to one that is =
less
elegant because of some new boxes or a fews gigs of memory is something =
I
would not recommend -- you would just be shifting your problems and =
thus
where you spend the money.
 
The first problem you will have is the load on the app server. With =
those
volumes, I would seriously recommend a dedicated application server for
workflow (steer via the RFC destination), otherwise you will probably =
buy
yourself complex problems in the existing system landscape.
 
Also, you need to plan stringent archiving of the workflow tables; =
workflow
contributed to system growth in the order of several Gigbytes per month =
(!)
in one of my larger implementations (several thousand workflows a day,
nothing like the volumes you are talking about). Probably daily or at =
least
weekly archiving will make sense.

Betreff: Your experience with performance
 
 
Hi all !
 
Has anyone of you made any experience with performance concerning =
workflow?
 
We are talking about 10,000 to 50,000 (ten to fifty thousand!) =
workflows,
and the same number of workitems sure, which will be started one day. =
These
workitems will then be worked with in 2 or 3 days and then there will =
be
once more 20,000 workitems started and wait for the users in the inbox.
 
The most critical problem I see are the role resolution to get the user =
or
organizational unit to execute a workitem. But if we leave this out of
sight, is it a problem for the system to handle the above mentioned =
number
of workitems?
 
Will there be a slow down of the system if there are 20,000 to 50,000
workitems waiting? Is the workflow engine running all the time or is it =
only
acitivated if a workitem is executed?
 
I hope to hear from you soon, as we have to decide to use workflow for =
this
amount of activities or any other technical solution.
 
Best regards,
 
Karsten
