My platform is Oracle 10g under Windows 2003 .
My database is in NOARCHIVELOG.Its complete dump file sizes 646MB,very important database and can't miss any data.Everyday It is exported in a schedule per day.I found the control files and online redo log files are multiplexed to the same drive. I am new here.
I think if any failure occurs now, I can't bring it back to point-in-time recovery.
Could you tell me your suggestions in a simple way and how to implement it and the backup procedures I should follow?
