System Administration Guide: Advanced Administration

Chapter 4 Managing System Resources (Overview)

This chapter provides a brief description of the system resource management features that are available in the Oracle Solaris OS and a road map to help you manage system resources.

Using these features, you can display general system information, monitor disk space, set disk quotas and use accounting programs. You can also schedule the cron and at commands to automatically run routine commands.

This section does not cover information on resource management that enables you to allocate, monitor, and control system resources in a flexible way.

For information on the procedures that are associated with managing system resources without resource management, see Managing System Resources (Road Map).

For information on managing system resources with resource management, see Chapter 1, Introduction to Solaris 10 Resource Management, in System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones.

What's New in Managing System Resources?

This section describes new or changed features for managing system resources in this Oracle Solaris release. For a complete listing of new features and a description of Oracle Solaris releases, see Oracle Solaris 10 9/10 What’s New.

New prtconf Option to Display Product Names

Solaris 10 1/06: A new -b option has been added to the prtconf command for the purpose of displaying a system's product name. This option is similar to the uname -i command. However, the prtconf -b command is specifically designed to determine the marketing name of a product.

The firmware device tree root properties that are displayed by using the -b option to the prtconf command are as follows:

To display additional platform- specific output that might be available, use the prtconf -vb command. For more information, see the prtconf(1M) man page and How to Display a System's Product Name.

psrinfo Command Option to Identify Chip Multithreading Features

Oracle Solaris 10: The psrinfo command has been modified to provide information about physical processors, in addition to information about virtual processors. This enhanced functionality has been added to identify chip multithreading (CMT) features. The new -p option reports the total number of physical processors that are in a system. Using the psrinfo -pv command will list all the physical processors that are in the system, as well as the virtual processors that are associated with each physical processor. The default output of the psrinfo command continues to display the virtual processor information for a system.

For more information, see the psrinfo(1M) man page.

For information about the procedures associated with this feature, see How to Display a System's Physical Processor Type.

New localeadm Command

Oracle Solaris 10: The new localeadm command allows you to change the locales on your system without reinstalling the OS or manually adding and removing packages. This command also allows you to query your system to determine which locales are installed. To run the localeadm command, you must have superuser privileges or assume an equivalent role through role-based access control (RBAC).

For more information, see the localeadm(1M) man page.

For more information in this guide, see Chapter 5, Displaying and Changing System Information (Tasks).
