Thanks for your reply Dirk!
What permissions are we exactly talking about? To give you further insight into my installation. I tried to run dbassist initially as user 'oracle' and later as a superuser. Now both these accounts have the same username and password on both machines. Moreover I used the user 'oracle' to do the Oracle install too. You referred to Sun Docs, are you talking about Sun Cluster 3.0 Docs?
