Dependency inside Cluster group when moving node

[Marcel Rüegg]

If I have several services inside one cluster group (Windows 2000) what
happens if I move this group to an other node. Will the dependency inside
the services also work the other way round when they go offline? So for an
example I have a service which uses an Oracle DB. In the the group I have a
dependency that first Oracle has to be available befor it can start the
service. What happens when I move the group to another node? Will the
service go offline befor Oracle will go offline?

The answer is 'Yes'

Dependencies work in both directions so if Service A is
dependant on Service B then Service A will not start until
service B has started when the group comes online, and
Service B will not stop until Service A has stopped when
the group goes offline.

By the way this also happens when you take resources
offline. In my example above taking Service B Offline will
also take service A Offline, but taking Service A offline
will not take service B Offline. Similarily if you bring
Service A Online it will also bring Service B Online, but
bringing Service B Online will not bring Service A online.

I have also assumed that the dependencies you refer to are
the ones set in the cluster and not the ones set in the
Windows poperties of each service.
