Hi
I am newbie , I know that we can restore the control file by using RMAN configure autobackup feature or by connecting Catalog
or issuing Alter database backup controlfile to trace .
but let us assume that there is no backup . You have the database running in nomount . I came across a blog that instructed to create control file manually and when there is any expected block number error came , the blogger used the forumale something like expected block number * 1024 / something . Lost the link to that blog
was just wondering is it even possible to create a controlfile from scratch . with limited information like datafile location , redo log size / location .
please can anyone let me know this in detail or shoot me that link !
Thanks
