Thank you for pointing to my paper. Recently, though, I have decided
that I will no longer say "You Probably Don't Need RAC" or anything to
that effect.
Instead, I'll give this statement to our customers:
"I would highly recommend the use of RAC. In fact, when in doubt, use
RAC. It's even free with Standard Edition.
Also, I want to stress that most customers should use partitioning. It
doesn't matter how big your tables are, or whether you have the perfect
partition key available - you should use it anyhow. It's cool, and it's
available. It's not free, but it's worth a lot of money to you.
Advanced Queueing, Advanced Replication, in general Advanced.* should
also be adopted agressively. Can't hurt, and it will make your business
more advanced.
Kind regards,
A (large) share owner of a consulting company.
PS: Oh, and do not ever create a system without DataGuard... "
It's my experience that this very, very positive message has a much
stronger impact on my listeners than the rather negative "You ....
Don't..." message.
