Hai,

oracle failsafe is only a software which will run on top of Windows NT cluster. With out oracle failsafe also windows NT cluster can move the database instance from one node to another, but when it moves it will do a shutdown abort and then move it. If oracle failsafe software is installed in the cluster and if you move the database form one node to another thru the failsafe , It will do a normal shutdown and move it to the other node. Basically this will ensure the database is in good condition when it is moving from one node to another.
