How to Associate a Pool With a Scheduling Class

You can associate a pool with a scheduling class so that all processes bound to the pool use this scheduler. To do this, set the pool.scheduler property to the name of the scheduler. This example associates the pool pool_batch with the fair share scheduler (FSS).

1. Become superuser, or assume a role that includes the Process Management profile.

   The System Administrator role includes the Process Management profile. For more information about roles, see "Using the Solaris Management Tools With RBAC (Task Map)" in System Administration Guide: Basic Administration.

2. Modify pool pool_batch to be associated with the FSS.

   # poolcfg -c 'modify pool pool_batch (string pool.scheduler="FSS")'

   
   

3. Display the edited configuration.

   # poolcfg -c info system tester string system.comment int system.version 1 boolean system.bind-default true int system.poold.pid 177916 pool pool_default int pool.sys_id 0 boolean pool.active true boolean pool.default true int pool.importance 1 string pool.comment pset pset_default pset pset_default int pset.sys_id -1 boolean pset.default true uint pset.min 1 uint pset.max 65536 string pset.units population uint pset.load 10 uint pset.size 4 string pset.comment boolean testnullchanged true cpu int cpu.sys_id 3 string cpu.comment string cpu.status on-line cpu int cpu.sys_id 2 string cpu.comment string cpu.status on-line cpu int cpu.sys_id 1 string cpu.comment string cpu.status on-line cpu int cpu.sys_id 0 string cpu.comment string cpu.status on-line pool pool_batch boolean pool.default false boolean pool.active true int pool.importance 1 string pool.comment string pool.scheduler FSS pset batch pset pset_batch int pset.sys_id -2 string pset.units population boolean pset.default true uint pset.max 10 uint pset.min 2 string pset.comment boolean pset.escapable false uint pset.load 0 uint pset.size 0 cpu int cpu.sys_id 5 string cpu.comment string cpu.status on-line cpu int cpu.sys_id 4 string cpu.comment string cpu.status on-line

   
   

4. Commit the configuration at /etc/pooladm.conf:

   # pooladm -c

   
   

5. (Optional) To copy the dynamic configuration to a static configuration file called /tmp/backup, type the following:

   # pooladm -s /tmp/backup

   
   

How to Set Configuration Constraints

Constraints affect the range of possible configurations by eliminating some of the potential changes that could be made to a configuration. This procedure shows how to set the cpu.pinned property.

In the following examples, cpuid is an integer.

1. Become superuser, or assume a role that includes the Process Management profile.

   The System Administrator role includes the Process Management profile. For more information about roles, see "Using the Solaris Management Tools With RBAC (Task Map)" in System Administration Guide: Basic Administration.

2. Modify the cpu.pinned property in the static or dynamic configuration:

   • Modify the boot-time (static) configuration:

     # poolcfg -c 'modify cpu <cpuid> (boolean cpu.pinned = true)'

     
     

   • Modify the running (dynamic) configuration without modifying the boot-time configuration:

     # poolcfg -dc 'modify cpu <cpuid> (boolean cpu.pinned = true)'
