Yep, HA means High Avalability, but usually used from a server's perspective, more than just Oracle. The issue here is Oracle licensing, standy=2 databases running (aka Oracle HA), hence additional oracle licenses. Server HA (HP MC Serviceguard, IBM HACMP, SunCluster, etc.)=1 database running shared between 2 servers with common storage but Oracle active on 1, hence no additional oracle license.

Gene,
HA means High Avalability.

>> shared storage,
Not really. You can implement HA by any means as long
as you ensure you have "High Availability". IMHO
standby is also something that is waiting to be
activated and "to become prod server". Actually
standby is normally a better HA because shared disks
would not protect you from disks "going south".
The point under discussion here, since you have missed
it, is whether standby could be considered oracle
"running" on standby host. ORACLE reps went on record
saying that you con not since the oracle "running" on
other server is in managed recovery mode.
