Chapter 2 - Oracle Database Architectures

Oracle on Unix Platforms

Performance is a key selling point for vendors in this environment and as a result, enterprise UNIX hardware, operating systems and database software are all designed for high performance. High-end enterprise servers have the capability of supporting hundreds of gigabytes of disk and can certainly support many hundreds of users. Until recently, the majority TPC-C and TPC-D benchmark records were held by hardware platforms running some flavor of the UNIX operating system. Windows and Linux are now beginning to challenge UNIX’s position as performance leader, recently capturing several TPC-C and TPC-D benchmarks.

All enterprise UNIX vendors must stress reliability to be competitive in the enterprise marketplace. In addition, many offer additional products that take advantage of UNIX clustering services. UNIX has almost thirty years of continuous development, making it the most mature of all operating systems with a proven track record of reliability.

The chart below provides a quick, high-level comparison of the three major operating systems in use today.
