Last updated on MARCH 26, 2020

Applies to:

Solaris Operating System - Version 10 3/05 and later
Information in this document applies to any platform.


The goal of this document is to assist in modifying what size pages can be used for memory used by a process. With the advent of applications or users could influence what size pages the kernel used and with the release of Solaris 10's LPOOB (Large Page Out Of Box) the default is to use larger pages when possible.

Note: This document will not address why you may want to modify these settings, only provide information as to how they can be changed. For more information on, why you may want to change these settings, please see the list of below referenced documents.
