(Sending again in plain text) Hi list, Well I think the subject speaks for itself, goal is to explain developers what should they be expecting when their instances are moved to RAC, maybe how the scan works, how rac works, etc , how their queries are executed.. Not a RAC training maybe just a quick introducing or features for developers doc.. any ideas? Is it any doc already created for this? I don't want to invent the wheel.
