I don't have RAC experience, but I am reading some RAC books/docs. I have questions about processes like DBWR in RAC. Lets say I have 10 DBWR and I have 4 RAC nodes. If I go to node 1, will I see 2-3 DBWR running on node 1? Do the DBWR run on different nodes as needed? I know that some processes (like LGWR) run on each node. But what about the ones that are not node specific?
