Chapter 2 - Oracle Database Architectures

Oracle Database Architectures

Extensive up-front analysis is critical during the architecture selection process, so let’s continue our discussion on Oracle database architectures by comparing three of the more popular Oracle database platforms: Oracle on Windows, Oracle on LINUX and Oracle on Unix. We’ll conclude with a database architecture comparison chart that compares the Windows, LINUX and Unix architectures.

Oracle on Microsoft Windows Platforms

Microsoft Window’s success as a server operating systems began when Microsoft released SQL Server 4.2 for the Windows NT operating system in 1994. Microsoft SQL Server 4.2 was a full-function relational database server with an attractive price tag. The traditional database competitors (Oracle, Informix, Sybase, IBM) realized that in order to compete in the departmental arena, they must begin to market a scaled down (and cheaper) version of their enterprise UNIX databases. Some of the workgroup database server products were simply the vendor's flagship enterprise database repackaged and re-priced to appeal to a different group of customers.

Database vendor competition is fierce in this environment. Microsoft’s attempt to dominate this architecture tier with SQLServer is forcing all vendors to adjust pricing and accelerate the release of new products as well as enhancements to existing products. This high level of competition between vendors allows consumers to take advantage of a high level of functionality at a reasonable cost.
