This chapter describes tuning steps designed to improve the performance and scalability of your Siebel Enterprise Server or Siebel Web Server Extension installation. It contains the following topics:

• Tuning Microsoft Windows for Enhanced Siebel Server Performance
• Tuning the Siebel Server for All UNIX and Linux Platforms
• Tuning the Web Server Computer for All Applicable UNIX and Linux Platforms
• Tuning the Siebel Web Server Extension for All UNIX and Linux Platforms
• Tuning an Apache Web Server for Applicable UNIX and Linux Platforms
• Tuning Siebel Business Applications for AIX
• Tuning Siebel Business Applications for HP-UX
• Tuning Siebel Business Applications for Oracle Solaris

Before doing any of the procedures in this chapter, you must have completed the minimum necessary steps described in the chapters about installing and configuring the Siebel Gateway Name Server and the Siebel Server contained in the Siebel Installation Guide for the operating system you are using. See also Siebel System Administration Guide and Siebel System Monitoring and Diagnostics Guide.

NOTE:  The settings provided in this chapter are based on a controlled lab environment using a standard Siebel application, such as Siebel Call Center. The degree of performance gained by using these settings at your site depends on your implementation. Contact your vendor for additional tuning recommendations for your supported operating system platform. Information is provided where tuning recommendations apply. In general, it can be assumed that tuning is not required if no recommendations are provided. For example, no information is provided about tuning the kernel on Linux operating systems, because such tuning is not necessary in those cases.
