Is HA singleton domain-wide?

[szczepan]

Hi,

I'm trying to use the HA singleton but it behaves unexpectedly. My configuration consists of a domain controller, two hosts (app-05, app-06), two groups (ADM, DEV), each group spans two hosts:

	host app-05	host app-06
profile/group ADM	server ADM_01	server ADM_02
provile/groupd DEV	server DEV_01	server DEV_02

When I deploy a HA singleton (even the official Quickstarts example) only one node of all groups runs the service. I would expect the singleton is unique for each group and separate groups start separate instances. Are there any changes required in a configuration to achieve this behaviour? In my case different groups/profiles run different versions of application and they should not form one cluster.

Thanks in advance

server-groups and clusters are orthogonal concepts.  To isolate clusters, use distinct multicast address/port per group.

I've already received the same answer (a bit more elaborate ;-) on Stack Overflow. Thanks anyway.
