"I think you missed the concept, deleting and discovering the node is not going to update the node, it's the other way around. If your services.ora is not being updated, the database won't show up once you updated the node."

Thank you. I'm well aware of the concepts and what a delete node and re-discover does.

I didn't say that discovering a node will update the node, did I?! It'll update your services.ora..
