Configuring Pools

How to Create a Static Configuration

Use the -s option to /usr/sbin/pooladm to create a static configuration file that matches the current dynamic configuration. Unless a different file name is specified, the default location /etc/pooladm.conf is used.

Commit your configuration using the pooladm command with the -c option. Then, use the pooladm command with the -s option to update the static configuration to match the state of the dynamic configuration.


Note - The new functionality pooladm -s is preferred over the previous functionality poolcfg -c discover for creating a new configuration that matches the dynamic configuration.


Before You Begin

Enable pools on your system.

  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. Update the static configuration file to match the current dynamic configuration.
    # pooladm -s
  3. View the contents of the configuration file in readable form.

    Note that the configuration contains default elements created by the system.

                            int     cpu.sys_id 0
                            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 Modify a Configuration

To enhance your configuration, create a processor set named pset_batch and a pool named pool_batch. Then join the pool and the processor set with an association.

Note that you must quote subcommand arguments that contain white space.

  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. Create processor set pset_batch.
    # poolcfg -c 'create pset pset_batch (uint pset.min = 2; uint pset.max = 10)'
  3. Create pool pool_batch.
    # poolcfg -c 'create pool pool_batch'
  4. Join the pool and the processor set with an association.
    # poolcfg -c 'associate pool pool_batch (pset pset_batch)'
  5. Display the edited configuration.
    # poolcfg -c info

  6. Commit the configuration at /etc/pooladm.conf.
    # pooladm -c
  7. (Optional) To copy the dynamic configuration to a static configuration file named /tmp/backup, type the following:
    # pooladm -s /tmp/backup

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 information on how to create the role and assign the role to a user, see “Managing RBAC (Task Map)” in System Administration Guide: Security Services.

  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

                            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)'

How to Define Configuration Objectives

You can specify objectives for poold to consider when taking corrective action.

In the following procedure, the wt-load objective is being set so that poold tries to match resource allocation to resource utilization. The locality objective is disabled to assist in achieving this configuration goal.

  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 system tester to favor the wt-load objective.
    # poolcfg -c 'modify system tester (string system.poold.objectives="wt-load")'
  3. Disable the locality objective for the default processor set.
    # poolcfg -c 'modify pset pset_default (string pset.poold.objectives="locality none")'
  4. Disable the locality objective for the pset_batch processor set.
    # poolcfg -c 'modify pset pset_batch (string pset.poold.objectives="locality none")'
  5. Display the edited configuration.
    # poolcfg -c info

  6. Commit the configuration at /etc/pooladm.conf.
    # pooladm -c
  7. (Optional) To copy the dynamic configuration to a static configuration file called /tmp/backup, type the following:
    # pooladm -s /tmp/backup

How to Set the poold Logging Level

To specify the level of logging information that poold generates, set the system.poold.log-level property in the poold configuration. The poold configuration is held in the libpool configuration. For information, see poold Logging Information and the poolcfg(1M) and libpool(3LIB) man pages.

You can also use the poold command at the command line to specify the level of logging information that poold generates.

  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. Set the logging level by using the poold command with the -l option and a parameter, for example, INFO.
    # /usr/lib/pool/poold -l INFO

    For information about available parameters, see poold Logging Information. The default logging level is NOTICE.

How to Use Command Files With poolcfg

The poolcfg command with the -f option can take input from a text file that contains poolcfg subcommand arguments to the -c option. This method is appropriate when you want a set of operations to be performed. When processing multiple commands, the configuration is only updated if all of the commands succeed. For large or complex configurations, this technique can be more useful than per-subcommand invocations.

Note that in command files, the # character acts as a comment mark for the rest of the line.

  1. Create the input file poolcmds.txt.
    $ cat > poolcmds.txt
    create system tester
    create pset pset_batch (uint pset.min = 2; uint pset.max = 10)
    create pool pool_batch
    associate pool pool_batch (pset pset_batch)
  2. Become superuser, or assume a role that includes the Process Management profile.

    The System Administrator role includes the Process Management profile. For information on how to create the role and assign the role to a user, see “Managing RBAC” in System Administration Guide: Security Services.

  3. Execute the command:
    # /usr/sbin/poolcfg -f poolcmds.txt
