Installation guide

In the example, a default class was created and all current processes were
assigned to that class. Class scheduling will be enforced even when the
CPU is idle and class usage will be reset every five seconds.
To review the current configuration, use the following command:
class> show
Configuration:
-Processes not explicitly defined in the database are
class scheduled.
-If the processor has some idle time, class scheduled
processes are not allowed to exceed their cpu percentage.
-The class scheduler will check class CPU usage every 2
seconds.
Class scheduler status: disabled current database: /etc/class
Classes:
default targeted at 100%:
class members:
Every one not listed below
The next step in the process is to create classes and populate the classes
with system processes such as tasks, daemons, or user accounts using the
appropriate identifiers such as UID or SESS.
4.7.5 Creating and Managing Classes
When the database has been configured, you can administer classes as
follows:
• Create a class:
– Add processes to the class
– Delete processes from a class
• Change the CPU access value (time percentage) of any class
• Destroy an entire class, whether empty or populated
• Show details of class members and configuration settings
• View statistics of actual CPU use against current priority settings
Some of these options are described briefly in the following sections. For
detailed descriptions of command options, refer to the help and reference
pages.
