Standby

  Dear All,

APPS(Prod)

DB(copy)

 (MACHINE #1)

DB(Prod)

APPS(copy)

(MACHINE #2)

Q1) Scenario:-

We have two machines we want to keep Apps( Production) on first machine and its DB(Production)

On second machine. For standby we keep backup of Apps(Production) of first machine on Second machine  similarly Copy of DB(Production)  on Second machine kept on First machine . By this way if our first machine will be down then we instantly up second machine similarly if Second machine downs then we up first machine. Is this Scenario possible? If some one guide me how I make this possible with very simple example. Any suggestion will be very helpful for us.
