ORCA should be able to start runs without TUBii, but on the teststand currently it seems as if you cannot start runs without TUBii. To reproduce, open the TUBii GUI and change the hostname to a non existent hostname and try to start a run. You should get the following error:
Run Not Started because of exception: RedisClient, reason: Operation timed out
I'm pretty sure that this used to work. @EdLeming any idea if any recent changes might have affected this?
