I'm trying to reimplement a vCAC extensibility use case using vCO and I need some feedback on my possible implementation.
Today I've got a scheduled workflow in vCAC which runs every 30 seconds and also is considered a "singleton" workflow.
This workflow will run every 30 seconds (not explicit interval, but it runs 30 seconds after the previous run completes), and at any given time there can only be a single instance of the workflow running.
The vCO options don't seem to have something which works quite what I was looking for. As far as I could tell what I need to do is to create a schedule which runs every minute and then set it to run @ 00s and @ 30s to give me something which runs every 30 seconds.
To get a situation like "single instance at a time" I was considering using a lock inside of my workflow, so if I can't obtain the lock I assume another instance of the workflow is running.
When actually running a schedule which looks like this however it doesn't seem to work like I expect. Initially the workflow was not running at all, and now it doesn't look like it runs @ 00 and @ 30, it only seems to run @ 00.
Is there a better way to implement something like this?
