Abstract

Oracle can do some things very differently when running on Exadata than when running on non-Exadata platforms. The optimizations provided by Exadata are designed to take a different approach than Oracle has traditionally followed. This change means that you need to attack some problems with a different mindset. That is not to say that everything is different—quite the contrary. In fact, most of the fundamental principles remain unchanged. After all, the same database software runs on Exadata that runs on other platforms. But there are some things that are just different. As you read in  Chapter 13, you can just take your database and deploy it 1:1 on Exadata. Depending on the type of deployment, this might be OK. However, if you are interested in getting the most out of your investment, you should probably take a step back and review what you can do to further optimize the database on Exadata. Since there are a few things that are different on Exadata compared to a standard, non-Exadata deployment, this chapter is worth reading for phase 2 of your migration. In this chapter, we will focus on how we should change our approach when running databases on Exadata.
