Hello,
 
everyday I have to do a cold backup of my database(shutdown all services). I wanted to delete a file in same directory as data folder(contains control and dbf files) but unfortunately I deleted part of the data folder: Some files in it were deleted(some a_txn files, some system files, 1 data file). Luckily I had a backup I took 2 days ago and managed to restore.
 
is it possible for me to retrieve all the data the day data folder I deleted? If I copy the datafiles in the deleted data folder and replace them in the restored data folder will it work?

Hi Roshan,

you need to recover them.
When you replace the deleted datafiles with the backup files taken 2 days ago, you need to do a recovery.
