We have a situation and would like to know if you can help to recover the data from Oracle database. 
 
 
 
Problem Statement :  Oracle Data files was deleted using OS command (rm –rf)
 
Environment : 
 
Database             : Oracle 11.2.0.4
 
                OS                          : RHEL 7
 
                Physical / VM     :  VM
 
Detailed description :
 
·         We have RMAN full backup taken on 14th Nov 2020
 
·         We do not have any other RMAN backups
 
·         We Have all archive logs from 17th Nov till 5th Dec 2020. (data files was deleted on 5th Dec)
 
·         We do not have Archive logs for 15th and 16th Nov 2020.
 
 
 
Please let us know is it possible to recover the data till 5th Dec 2020.  
 
 
 
 
 
We can provide two option :
 
1. prmscan , please reference : https://youtu.be/skH9nJOvIkQ  , it can scan the disk and find deleted datafile blocks ,merge them . But You'd better make a vm snapshot first,otherwise deleted datafile block may be overwritten .
2. We can help you recover data from 14th Nov 2020 backup, we can force skipping the missing archivelog , but apply others.
