Question

Configure how many instances of workflow can run at one time.

asked on September 16, 2015

A client asked me this question:

 

Is there a place I can configure how many instances a worksflow can have?

 

I have one process that isn’t used that often, however if there a multiple instances of it running it has the tendency to fail.


I want this one process to only have one instance running at any given time.

 

How can I change this?

See this help page. You can configure that specific workflow to run in single instance mode.

I just want to confirm something regarding the SINGLE INSTANCE MODE.

It reads it will wait for a "specific schedule workflow to run at a time" so doe this mean it only applies to Workflows with a SCHEDULE STARTING RULE? That seems to be the case as I tried it with a "ENTRY CREATED" Starting Rule and it does not seem to apply.

So through much testing it seems that SINGLE INSTANCE MODE works like this.

Workflows initiates, if the same Workflow tries to initiate it ignors and never runs it.

Workflow Instance 1 Initiates

Workflow Instance 2 Starts (Instance 1 is still running)

Instance 2 is ignored and never runs.

I was hoping that the following would occur. 

Workflow Instance 1 Starts

Workflow Instance 2 Starts (Instance 1 is running) que Instance 2

Run Instance 2 once Instance 1 completes.
