Hi

Today my boss asked me what high availability does Oracle offer, I mentioned Parallel Server & Advanced Replication. Our enviroment is already using Sun Cluster technology in a data center so I told him that OPS would offer availability + load balancing now he asks me about Replication I went a bit stoned because I think Replication is really for disasters like the whole data center gets blown up and we would have another replication in another city. And I dont see much point of having two server replicating each other in the same building.
Anyone have a suggestion of using OPS or Replication? I would guess OPS is cheaper to setup?

Having a standby database in an environment with Raid 5 would there be any benefit at all since we have redundant disks in our situation so in case of disk corruption we can still recover. Would standby database provide any improvement in case we lose a disk for whatever reason?

By the way since I am not an expert with Solaris does anyone know if Sun Cluster offers load balancing for database servers? (As far as I know it only offers availability)


Cheers
