I'm still unclear about Data Guard and using REDO logs vs archived logs. Does DG stirctly use archived logs, and if that's the case, hwo the heck does it stay in sync if you have to wait for redo logs to be archived before shipping?
Does DG use redo logs for one mode and not another, or some mix of the two? Please clarify! I apologize in advance, I have been reading documentation but I can't say I see anything that clears doubt :-/ Example - I see the term "redo data." Can I assume this means DG uses redo logs and not archived logs?
