RC_DATABASE_INCARNATION

This view lists information about all database incarnations registered in the recovery catalog.

Oracle creates a new incarnation whenever you open a database with the RESETLOGS option. Records about the current and immediately previous incarnation are also contained in the V$DATABASE view.
