Setting up the FSS

For a good overview of all FSS options please go to link System Administration Guide: Virtualization Using the Solaris Operating System.

Although only one server is used in the following examples, all of the following steps much be executed on all servers within the cluster.

Displaying default scheduling class

To displays the name of the default scheduling class to be used on reboot, use the dispadmin -d command. The first output is when there is no default scheduling class set.

[root@banpapp2 ~]# dispadmin -d
dispadmin: Default scheduling class is not set

The second output is when the default scheduling class is set to FSS.

[root@banpapp2 ~]# dispadmin -d
FSS     (Fair Share)

Setting the default scheduling class to FSS

To set the default scheduling class to FSS:

[root@banpapp2 ~]# dispadmin -d FSS
[root@banpapp2 ~]# dispadmin -d
FSS     (Fair Share)

Making the configuration take effect immediately

Make this configuration take effect immediately, without rebooting:

[root@banpapp2 ~]# priocntl -s -c FSS

Moving all processes to the FSS scheduling class

Move all processes from the ALL scheduling class into the FSS scheduling class.

Move the init process (pid 1) into the FSS scheduling class.

[root@banpapp2 ~]# priocntl -s -c FSS -i pid 1

Move all processes from their current scheduling classes into the FSS scheduling class.

[root@banpapp2 ~]# priocntl -s -c FSS -i all
