Configure FSS project.cpu-shares for a Project - Resource Management and Oracle® Solaris Zones Developer's Guide

Language:

Configure FSS `project.cpu-shares` for a Project

Set up FSS for two projects: database and appserver. The database project has 20 CPU shares. The appserver project has 10 CPU shares.

hostname# cat /etc/project

.
.
.
user.database:2001:database backend:admin::project.cpu-shares=(privileged,
     20,deny)
user.appserver:2002:Application Server frontend:admin::project.cpu-shares=
     (privileged,10,deny)
.
.
.

Note - The line break in the lines that precede “20,deny” and “(privileged,” is not valid in an /etc/project file. The line breaks are shown here only to allow the example to display on a printed or displayed page. Each entry in the /etc/project file must be on a single line.

If the FSS is enabled but each user and application is not assigned to a unique project, then the users and applications will all run in the same project. By running in the same project, all compete for the same share, in a timeshare fashion. This occurs because shares are assigned to projects, not to users or processes. To take advantage of the FSS scheduling capabilities, assign each user and application to a unique project.

To configure a project, see Local /etc/project File Format in Administering Resource Management in Oracle Solaris 11.2 .
