I am contemplating if a cluster will really improve our GroupWise up time.
Most of our issues regarding down time is GroupWise IA or WebAccess Agents
issues. With Groupwise IA it is usually a bad message that crashes the IA.
Since in a cluster you have to have shared data, wouldn't the second
Internet Agent have the problem with the same bad message. Thus, possibly
crashing that system too?

I guess my general question is:

Are you implementing clustering to help with Hardware Failure & Uptime
during Hardware Maintenance?
Are you implementing clustering to help with Abends and other software
issues ?

In what scenarios has the cluster really paid off in your implementation?

Thankyou so much for any inputs with this question.
