CHAPTER 1 Overview of Solaris System Tuning This section provides overview information about the format of the tuning information in this manual. This section also describes the different ways to tune a Solaris system. ■ “What’s New in Solaris System Tuning in the Solaris Express 6/05 Release?” on page 19 ■ “What’s New in Solaris System Tuning in the Solaris 10 release?” on page 20 ■ “Tuning a Solaris System” on page 25 ■ “Tuning Format of Tunable Parameters Descriptions” on page 25 ■ “Tuning the Solaris Kernel” on page 27 ■ “Special Solaris tune and var Structures” on page 30 ■ “Viewing Solaris System Configuration Information” on page 30 ■ “kstat Utility” on page 31 What’s New in Solaris System Tuning in the Solaris Express 6/05 Release? This section describes new or changed parameters in the Solaris Express 6/05 release. ■ “sq_max_size” on page 19 ■ “TCP keepalive Parameters” on page 20 sq_max_size The default value of this parameter was incorrectly documented in the Solaris 10 release. For more information, see “sq_max_size” on page 175. 19
