However, failed transactions must be handled from
client side. Queries may migrate to surviving nodes transparently.
Also, currently RAC has many problems, such all
nodes hanging when one node dies. Completely separate systems are still (an will
always be) the most available solution.

Another Important different is
that RAC is best High Availability solution in case of System/Instance Failure
where in case of HP or Veritas Cluster, all of the resource get stopped on
live system/node of the cluster and then get started on second node and hence
user will be affected. But in case of system or Instance failure, there is
seamless transition of the User session in RAC

ak,
As I understand it, an HP cluster is 2 boxes that have the
capability
to access the same disks and data but only one can have the
oracle
instance running and accessing the datafiles(active). Sort of like
a
high availability option.
With RAC both boxes can access the instance
and datafiles at the same
time.
List, Correct me if I need
it.
