Dedicated server for WF

[Soady, Phil]

Hi Koenraad,
You need to separate event handling from wf-batch user steps.
 
Event handling you now know.  Swe2 settings unless the Event queue is in place.
 
Background steps are executed as per  the SM59 settings for the workflow local connection. Im not sure if it is possible to influence where the
WORKFLOW_LOCAL_xxx runs. I haven't tried the reference RFC connection inside SM59. In theory you can get it to use a another RFC destination.
This RFC destination could use load balancing. But I haven't tried it.
 
What You can also do is influence where the Job/ABAP runs that causes the next step to happen. So therefore influence where the function swe_xxxxxx  get called from.  eg Event queue, or deadline monitor. So I think there is some control here you can have on where things are executed indirectly.
 
Has anyone tried deleting the RFC destination WORKFLOW_LOCAL_XXX
And recreating it as type 3 instead of L. ? This may also provide a way to directly influence where the wf-batch background steps run.

When I say fail.. I mean go offline.... (by whatever reason)
 
Yes we use sweqadm to track events which weren't delivered.  And I've seen
that RSWEQSRV runs on every client.  But not on intervals so I guess it's automatically
scheduled by the WF system.
 
I think I'm just going to try it on our development and acceptance system.
 We'll see how it goes....
Anyway is only the initial event handling done on the mentioned server or
does the whole workflow run on it?
 
Kind regards

Does it fail...? What dou you mean by fail...
 
It might... but its not "lost" and the load balancer can be changed (SMLG)
so that attempts to logon to instance A end up on B.
But if all instances are busy... then it must "fail" as you call it.
FULL is FULL. What does all this mean.
The Destination can be used to go to another available server, YES.
If that server is full, then all bets are off.
 
 
If your administrator is familiar with such games (s/he has multiple
instances and logon groups'
under control) then they already have such concerns addressed.
 
SM59 still allows for a last minute change of app server anyway.
 
Go ahead a let them move initial event handling to another server.
BTW....Do you have the event q turned on.
SWEQADM ?
No?.... Now mention the event queue to them.
Careful you will need a bucket as they may start salivating excessively.
 
Now they can control the processing of events in a controlled manner.
Although the default schedule button in SWEQADM doesn't offer it,
ABAP    RSWEQSRV can be scheduled manually to run every minute on a
specific server.
So before you do mass maint on SWE2... take a look at SWEQADM.
 
Cheers

Dear WF users
 
Our system folks are trying to talk us into using a dedicated workflow
server by routing the RFC destinations in transaction swe2. (cfr SapNote
98407)
Now offcourse we are pro everything which could improve workflow and
system performance however I would like to know if any of you have had
experiences with this and how did it work out?
 
Especially I would like to know of experiences when something goes wrong.
What happens if this dedicated server fails and goes offline.  Does the
system switch back to searching available processes on all application
servers or just fails?
 
Thank you in advance for any information you might possibly have...
