[HPADM] RE: Input About Oracle RAC

On Oracle RAC you get high-availability, load balancing, especially if you
use ASM to manage the storage. But the main problem is VERY hard management
of more then 3 servers, but this is duty of DBA, not sysadmin. Balancing of
load is almost nightmare :-). And do not use NAS for shared storage (via NFS
mounts) but SAN

Subject: [HPADM] Input About Oracle RAC



This is sort of off-topic, but there I am engaged in discussions about the
pros and cons of installing and supporting Oracle RAC as a replacement
architecture to the standard database deployments on single servers.



Does anyone on this list have experience with configuring and installing
Oracle RAC in an HP-UX and/or Linux environment? If so, what are your
opinions regarding this? Have you seen any performance improvements, etc.?
Is there a benefit with large (> 1TB) database instances?



Thanks, and I will summarize.
