Tanel,
I think that you've had some unfortunate experiences with RAC. Mind
elucdating them ?
I don't see nodes hanging when one node dies [I'm running a 2-node Tru64
RAC Cluster]

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.
Tanel.

- 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.
