Identify three ways in which the Fair Share Scheduler can be assigned.
A. poolcfg
B. dispadmin
C. zonecfg set pool=<value>
D. zonecfg set cpu-shares=<value>
E. by creating a project and attaching a process to that project
Correct Answer: ABD
Explanation/Reference:
Explanation:
A: Resource Allocation: Zones, Pools and FSS
Example:
Then create a pool for your zone (in this example, we’ll use the zones named ‘habitue,’ ‘creator,’ ‘netid,’ and ‘linguo’): pooladm -x
pooladm -s
poolcfg -c ‘create pool habitue-pool ( string pool.scheduler = "FSS" )’ poolcfg -c ‘create pool creator-pool ( string pool.scheduler = "FSS" )’ poolcfg -c
‘create pool linguo-pool ( string pool.scheduler = "FSS" )’ poolcfg -c ‘create pool netid-pool ( string pool.scheduler = "FSS" )’ pooladm -c
B: Set the default scheduler for the system to be the FSS.
# dispadmin -d FSS
D: Example:
global# zonecfg -z global
zonecfg:myzone> set cpu-shares=100
zonecfg:myzone> set scheduling-class=FSS
zonecfg:myzone> exit

Answer BDE
E: Projects are the workload containers in the FSS scheduler. Groups of users who are assigned to a project are treated as single controllable blocks. Note that you can create a project with its own number of shares for an individual user.
Users can be members of multiple projects that have different numbers of shares assigned. By moving processes from one project to another project, processes can be assigned CPU resources in varying amounts.
