The Oracle Solaris Tunable Parameters Reference Manual provides reference information about Oracle Solaris OS kernel and network tunable parameters. This manual does not provide tunable parameter information about desktop systems or Java environments.
This manual contains information for both SPARC based and x86 based systems.
This Solaris release supports systems that use the SPARC and x86 families of processor architectures. The supported systems appear in the Solaris 10 Hardware Compatibility List at http://www.sun.com/bigadmin/hcl. This document cites any implementation differences between the platform types.
In this document these x86 terms mean the following:
“x86” refers to the larger family of 64-bit and 32-bit x86 compatible products.
“x64” relates specifically to 64-bit x86 compatible CPUs.
“32-bit x86” points out specific 32-bit information about x86 based systems.
For supported systems, see Solaris 10 Hardware Compatibility List at http://www.sun.com/bigadmin/hcl.
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.
