Preface
Solaris Tunable Parameter Reference Manual provides reference information about Solaris kernel and network tunable parameters. This manual does not provide tunable parameter information about the CDE or Java environments.
It contains information for both SPARC™ based and IA based systems.
Note - The Solaris™ operating environment is supported on two types of hardware, or platforms--SPARC and IA. The Solaris operating environment supports 64-bit and 32-bit address spaces. The information in this document pertains to both platforms and address spaces unless specified in a special chapter, section, note, bullet, figure, table, example, or code example.
Who Should Use This Book
This book is intended for experienced Solaris system administrators who might need to change kernel tunable parameters in certain situations. For guidelines on changing Solaris tunable parameters, refer to "Tuning a Solaris System".
