Any cron jobs running at that time, clearing any temp files? Check the time window and crontab.

thanks a lot for your answer .

i check this subject that view that results.

which temp file must be deleted?

Well, as this is happening in every two weeks, I expect some cron tab job kicked in, trying to clear some temp files and may be deleted your control files. This is just a possibility... By any means, Oracle cannot delete the control files automatically..

Please don't ask what are those temp files :)

Hi

thanks for your answer

I have checked cron and there is no schedule task for this subject.

Check root crontab and all other powerfull users crontab
