关于incarnation,有这样一段解释:

Whenever you perform. incomplete recovery or perform. complete or incomplete
recovery using a backup control file, you must reset the online redo logs
when you open the database. The new version of the reset database is called
a new incarnation. All archived redo logs generated after the point of the
RESETLOGS on the old incarnation are invalid in the new incarnation.

If you perform. complete recovery, then you do not have to open the database
with the RESETLOGS option: you simply open the database as normal. All previous
backups and archived logs created during the lifetime of this incarnation of
the database are still valid.
