Our Remote DBA group has a debate
going on about whether or not Oracle Grid
Control should be placed in the Oracle RAC
environment, or should it be on it’s own
standalone server exclusive of the RAC. Is
Grid always the best choice for a RAC
architecture? What do you think about
using RAC with a small number of large servers
instead? Do you recommend using a RAC and
Grid expert for advice?
Answer: Donald K.
Are you using RAC for
scalability, failover, or disaster recovery?
Your choice of RAC and Grid architecture depends
on your goals.
Many shops that I work with
use just a few large SMP servers, instead of
dozens of server blades. Sometimes it's far
easier to provision computing resources within a
scalable Oracle SMP server (by simply adding
more RAM of CPU's) than it is to take the server
blade approach and the associated complexity of
setup and grid management. Some
large RAC data warehouses bypass Grid
Control with server blades
I also recommend that your
Remote DBA team get Mike Ault's Oracle
10g Grid and RAC book.
I recommend getting a
real-deal Grid expert on-site for a few days?
Implementing Grid control is VERY complex and
tricky, and you must have exactly the
recommended hardware and software.
I don't recommend that any
shop try it without advice from someone who has
done it before. BC consulting has
RAC and Grid experts available to guarantee
your success. Don't take chances.
