Oracle Alter Database ResetLogs

I would like to know is it necessary to issue Alter Database ResetLogs
if I restore the entire database from the backup and restore everything from the Archived Re-Logs after any diaster that I lose everything.

As I know, onlyl incomplete recovery needs to issue Alter Database ResetLogs, but isn't restore everything from the backup and recover the database is a COMPLETE RECOVERY? I am so confused.

Yes.  Unless you did a recover until cancel or some other point-in-time recovery.

You do not need to open resetlogs on a complete recovery.


As always, the docs have the information you need:

Database Incarnations
 
A database incarnation is created whenever you open the database with the RESETLOGS option. After complete recovery, you can resume normal operations without an OPEN RESETLOGS.
