Re: Moving from single instance to RAC

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.
