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.
