I want to discuss one scenario !!

I have two servers clustered for failover :

1)Operatin system is Linux Redhat.

2)Both Server have Oracle Database (DB) with Applications(Same Application and Database on two servers). Active & Passive

3)Now i want if Applications fails then process automatically switch to Server two application && If database fails then automatically switch to Server two database and Vice Versa(Server two fail then switch to Server 1)


May be fencing is also required for this scenario , i think i have to use Fabric Fencing instead of Power Fencing.


Do share your comments !!

Thanks
