Performing basic system tuning and monitoring

Administering multiple processors and processes

Use the Processor Manager to switch processors on and off, and to see the details of processors. It is accessible from the Hardware folder of the scoadmin(1M) launcher, or by entering scoadmin hardware prs on the command line. The Processor Manager displays the processors on the current system.

NOTE: You can administer processors on remote machines using the Host

Open Host menu selection of the Processor Manager. See ``Managing host groups'' for more information.

To switch a processor on or off, click the name of the processor to highlight it, then select Action Start/Stop. A processor that is running is stopped, and a processor that is stopped is started.

Multiple processors can be taken on or off line at the same time. In a graphical environment:

Hold down <Ctrl> and click the name of the processors you want to take on or off line.
Select Action Start/Stop.

In character mode:

Select the processors from the list by pressing <Enter>. A * character appears by each selected processor.
Select Action Start/Stop.

To view the details of a processor, highlight the processor, then select Action Properties. See psrinfo(1M) for information about the details displayed.

In addition to the Processor Manager, four administrative commands are available to help you manage multiple processors and processes. The psradm(1M) command allows you to alter the administrative state of processors, while the psrinfo(1M) command allows you to display information about processors in a similar way to the Processor Manager.

The pbind(1M) and pexbind(1M) commands allow you to control the processes running on a processor. Users can explicitly bind one or more processes to a processor, with or without excluding other processes. Specific processors are referred to by processor_id, and an option allows you to specify that all processors are targeted for the operation.
