Question

configuring multiple workflows servers against same repository

Workflow Administration

We have a repository which has a workflow server configured and it's all working fine. All the workflows configured at this WF server are triggering fine as expected.

Now we have a requirement of configuring two additional Workflow servers against this same repository. My understanding is, it is fine and this is possible. So while configuring the second WF server against this repository, we get this message: "The WFUser$ account is already enabled and may be in use by another Workflow Server. The account password will be reset in the registration process." (attached)

So when we click Yes here, as expected the first WF server throws error about can't connect to repository.

How can we configure multiple WFs to the same repository?

You want to use the Attach button on the same dialog instead of the Add one. That will prompt you to provide the address of the first server and set the second one to use the same password.

Hi Miruna, could you please help me to understand the behaviour of the starting rules in this scenario...¿?... Each one WF server has its own db or is the same for all. How they know to not start an instance that was already started for a document in another wf server..¿?

Damon,

We have to process very large number of documents using some complex workflows. So the purpose of setting up new WF servers is, we will be running those workflows on these new WF servers and not to burden the current Live WF server which is running Live workflows.

These two new servers will be gone in about a month.

Does that make sense?

Thanks,

Uzair

Uzair,

If I may ask, what is the scenario that requires multiple workflow servers to be servicing the same repository? I can't think of one, so I'm just curious!

Thanks, Damon

One reason to use multiple servers is to distribute load in high activity environments. Workflow benefits from having more CPUs rather than powerful CPUs.
