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.
