Can Not Recover From Last Archive Log

السلام عليكم ورحة الله
انا اقوم بعمل test حيث اخد full backup عن طريق rman بعد ذلك اعمل تغيير على قاعدة البيانات ومن ثم اعمل alter system switch logfile .وينتج عن ذلك archive log file جديد.بعد ذلك اقوم باعمل shutdown لقاعدة البيانات واخد نسخة للكنرول فايل .ومن ثم اعمل crash لقاعدة البيانات واقوم باسترجاع الكنترول فايل ويتم الاسترجاع بنجاح من النسخة للكنترول فايل .بعد ذلك اعمل استرجاع datafile من rman backup ويتم الاسترجاع بنجاح.لكن عندما اعمل recovery يعطيني هذا الخطاء

حيث O1_MF_1_1_5YNK6R75_.ARC الملف الذي ينتج عن عملية alter system switch logfile المذكورة سابقاَ .
لكن عنما اعمل RMAN> RUN
2> {
3> SET UNTIL sequence=10 thread=1;
4> RESTORE DATABASE;
5> RECOVER DATABASE;
6> }

تنجح العملية.
السوئال هو لماذا لايتم عمل الريكوفيري من اخر archive log file على الرغم من اني اخد نسخة للكنترول فايل بعد عملية switch logfile .مع العلم انا هذه العملية تكررت معي العديد من المرات حيث يرفض عمل الريكوفيري من اخر نسخة لarchive log file وياخد التي قبلها.
