Home -> Community -> Mailing Lists -> Oracle-L -> RE: 9i standby
No it is not the upgrade of OPS as I understand. They even put OPS down themselves saying that it was sparsely used, and far to complicated to set up.
What RAC does, is essentially link every machine together in to a "cluster", then each physical machine can touch the same database concurrently (probably on a central storage unit). There is no actual "standby" when this is in use, as all machines connected to the cluster work together - but if one of the machines has a hardware failure, the load is simply spread between the remaining machines..
It looks *really* cool stuff, and by *Oracles* stats, beats any other clustered databases in real world situations.
If only I could blag the boss for a ?1,000,000 budget for a bunch of compaq servers >:-)

Mark, isn't RAC just the upgrade for OPS? Then that would make it a 'standby' for the instance, but not a standby for the database, no?
Am I misunderstanding something?
