RMAN removes archived redo logs required by Integrated Extract when using a BACKED UP TO archive deletion policy
When you query to find the archived log file based on SCN, they appear to have been deleted due to RMAN policies--archive logs are backed up every two hours. The logs are then deleted after they've been backed up twice.
