Escenario 2

El escenario es el siguiente, luego de un upgrade sobre una base 10.2.0.4 para actualizar a 11.1.0.6, la base presento un fallo irrecuperable, y hubo que restaurar del backup tomado con anterioridad.
La base esta en modo NOARCHIVELOG, y la estrategia de backup es incremental.
Previamente, se guardó la estructura de la BD.

Ahora necesitamos conocer cuál fue el ultimo INCREMENTAL LEVEL 0 que se realizó de la base.
Contamos con un backup incremental level 0, y 3 backups incrementales level 1. La recuperacion sera entonces, un restore al level 0, y un recover al tercer level 1.
