Thanks Peter,
We are staying on AIX platform only.
We are implementing RAC on stretched cluster. We do have similar test
environment and the users, application owner are satisfied with the test
results.
Application is very highly OLTP system, around 500 transaction per second
and more than 2000 connections coming from Application Servers.
Although we have no issues with single-instance, we need to have high
availability and scalability options to further increase the database
throughput.

Hi
Are you staying on AIX or moving to Linux
From Jarrods survey you will be in a minority group of sites running RAC
and it makes sense not to use high costs subsystems like AIX servers to be
your RAC hosts.
Why are you moving to RAC, what problem is it you are trying to solve
You need to test and test and test some more before going live and load
test your application or it may get very messy after you go live
Without knowing the application of if its an inhouse application then its
difficult to say much
You need to consider if you need multiple sets of clusters for your site
You have to use RMAN
Cheers

List,
We are planning to move one of our highly OLTP Oracle 10gR2 database on
AIX from single instance to 2 node RAC.
I just would like hear from any of one here about the issues or potential
problems when moved from a single instance to RAC.
I would be gald if you guys share you experince or throw some limelight or
tips.
Thanks your time,
