Oracle9i Application Server Oracle HTTP Server powered by Apache Performance Guide Release 1.0.2.2 for Sun SPARC Solaris Part Number A86676-02 |
|
This guide discusses configuration and performance tuning of the Oracle HTTP Server powered by Apache.
There are many sources of information on configuring and tuning web servers, Apache in particular. This guide refers to those sources when expedient, and, where practical, quantifies the performance gains resulting from configuration actions found in those sources. Any recommendations not validated by Oracle in-house testing are cited as such, with attribution to the original source.
All in-house tests detailed in this guide were run on a dedicated 100 Mbps network, in order to achieve repeatable test results. Your results will vary based on network configuration and contention characteristics.
This preface contains these topics:
This guide is written for Oracle9i Application Server developers and system administrators who are responsible for configuring and tuning the Oracle HTTP Server powered by Apache.

This section describes the conventions used in the text and code examples of the this documentation set. It describes:
We use various conventions in text to help you more quickly identify special terms. The following table describes those conventions and provides examples of their use.
Code examples illustrate SQL, PL/SQL, SQL*Plus, or other command-line statements. They are displayed in a monospace (fixed-width) font and separated from normal text as shown in this example:
SELECT username FROM dba_users WHERE username = 'MIGRATE';
