System Administration Guide: Virtualization Using the Solaris Operating System

Setting Pool Attributes and Binding to a Pool

You can set a project.pool attribute to associate a resource pool with a project.

You can bind a running process to a pool in two ways:

  • You can use the poolbind command described in poolbind(1M) command to bind a specific process to a named resource pool.

  • You can use the project.pool attribute in the project database to identify the pool binding for a new login session or a task that is launched through the newtask command. See the newtask(1), projmod(1M), and project(4) man pages.

How to Bind Processes to a Pool

The following procedure uses poolbind with the -p option to manually bind a process (in this case, the current shell) to a pool named ohare.

  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. Manually bind a process to a pool:
    # poolbind -p ohare $$
  3. Verify the pool binding for the process by using poolbind with the -q option.
    $ poolbind -q $$
    155509 ohare

    The system displays the process ID and the pool binding.

How to Bind Tasks or Projects to a Pool

To bind tasks or projects to a pool, use the poolbind command with the -i option. The following example binds all processes in the airmiles project to the laguardia pool.

  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. Bind all processes in the airmiles project to the laguardia pool.
    # poolbind -i project -p laguardia airmiles

How to Set the project.pool Attribute for a Project

You can set the project.pool attribute to bind a project's processes to a resource pool.

  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. Add a project.pool attribute to each entry in the project database.
    # projmod -a -K project.pool=poolname project

How to Use project Attributes to Bind a Process to a Different Pool

Assume you have a configuration with two pools that are named studio and backstage. The /etc/project file has the following contents:

user.paul:1024::::project.pool=studio
user.george:1024::::project.pool=studio
user.ringo:1024::::project.pool=backstage
passes:1027::paul::project.pool=backstage

With this configuration, processes that are started by user paul are bound by default to the studio pool.

User paul can modify the pool binding for processes he starts. paul can use newtask to bind work to the backstage pool as well, by launching in the passes project.

  1. Launch a process in the passes project.
    $ newtask -l -p passes
  2. Use the poolbind command with the -q option to verify the pool binding for the process. Also use a double dollar sign ($$) to pass the process number of the parent shell to the command.
    $ poolbind -q $$
    6384  pool backstage

    The system displays the process ID and the pool binding.
