Im facing this problem with Orquestration Server 8.1.400.77
“This node is not operational - ORS Cluster is not configured”
I can not route an interaction because of ORS, it seems I could not configure the cluster well
On the cluster section, the Key should be the application name and the value some “site” name. Also, since your transaction name is not ORS, it should be in the Command Line parameters of the Start Info tab of Orchestration Server. In your case, you should add ‘-cluster “ORS CLuster”’ (avoid using spaces…)
From provided screenshots it seems your Transaction list is configured with name “ORS_CLuster”, but the start-up parameter is configured with value “-cluster ORS_Cluster” - due to the ORS looks for objects using case-sensitive, it will fails as there is no object “ORS_Cluster” at all. Repair/Fix the name of the transaction list and restart ORS, than it should work as expected.
