CHAPTER 8
Exadata and OLTP

When the first Oracle Exadata Database Machine, the HP Oracle Database Machine, was introduced, it represented the first version of the power of the Database Machine. This version was aimed at delivering extreme performance for data warehousing, performance many times faster than was previously achievable with standard database systems.

Version 2 of the Database Machine, the Sun Oracle Database Machine, was released about a year later, with additional capabilities. This version of the Database Machine not only further improved performance for data warehouse workloads, but also provided a solution that delivered extraordinary performance for OLTP workloads. The X2 versions of the Oracle Exadata Database Machine provided even more flexibility in deployment choices for OLTP workloads.
