Solaris Tunable Parameters Reference Manual
PrefaceSolaris 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.
