Integration

Originally I have two instances listed in the farm list (App Server Control) as: infra and mtier. After we crashed the mtier box, we reinstalled it with a different name: mtier_rebuilt (not allowed by Oracle to use the old name, mtier). Now the farm list shows all three instances while the old mtier one is actually a broken link. How do I remove it from the list?

The tricky part here is that if we use dcmctl to remove an instance, I'm afraid that it will remove both mtier instance. Any ideas?

Thanks in advance
