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.
