but what happens when the shared device crashes or fails. How do you make sure that this does not introduce downtime in your setup.

Ah, the $64,000 question. The key is to configure your disk with redundancy (ie RAID). You must look at each component and determine if it is a single point of failure. If it is, there must be a backup for it.


and also if there is one shared storage and multiple nodes will be accessing it.... wont I need to configure Oracle Parallel server ???I didnt see any mention of this in the articles on oracle's web site.

No, failsafe (as I understand it) is a failover technology and not a parallel technology. For example, you have two boxes b0 and b1. With failsafe, b0 will handle all the requests. When b0 dies, b1 kicks in and processes requests. When b0 is alive, b1 does nothing (in terms of servicing requests).

With parallel server, both b0 and b1 will be servicing requests. When b0 goes down, b1 takes over b0's requests and continues service his own requests.
