Assign the specified processors to the specified processor set. With the additional -F option, all LWPs bound to the specified processors will be unbound prior to changing processor sets. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Bind all or a subset of the LWPs of the specified processes to the specified processor set. If -z is specified, all processes and threads inside the specified zone are bound to the processor set. LWPs bound to a processor set are restricted to run only on the processors in that set. Processes can only be bound to non-empty processor sets, that is, processor sets that have had processors assigned to them. Bindings are inherited, so new LWPs and processes created by a bound LWP have the same binding. Binding an interactive shell to a processor, for example, binds all commands executed by the shell. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Create a new processor set and displays the new processor set ID. With the additional -F option, all LWPs bound to the specified processors will be unbound prior to assigning them to the processor set being created. If a list of processors is given, it also attempts to assign those processors to the processor set. If this succeeds, the processors are idle until LWPs are bound to the processor set. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege. Only a limited number of processor sets can be active (created and not destroyed) at a given time. This limit is always be greater than the number of processors in the system. If the -c option is used when the maximum number of processor sets is already active, the command fails. The following format is used for the first line of output of the -c option when the LC_MESSAGES locale category specifies the "C" locale. In other locales, the strings created, processor, and set can be replaced with more appropriate strings corresponding to the locale.

"created processor set %d\en" processor set ID

Remove the specified processor set, releasing all processors and processes associated with it. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Execute a command (with optional arguments) in the specified processor set. The command process and any child processes are executed only by processors in the processor set. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Disables interrupts for all processors within the specified processor set. See psradm(8). If some processors in the set cannot have their interrupts disabled, the other processors still have their interrupts disabled, and the command reports an error and return non-zero exit status. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Forces the specified processor set operation by unbinding all threads bound to the specified processor. Only the -a or the -r option can be used in combination with this option. Administrators are encouraged to use the -Q option for pbind(8) to find out which threads will be affected by such operation.

Display a list of processors assigned to each named processor set. If no argument is given, a list of all processor sets and the processors assigned to them is displayed. This is also the default operation if the psrset command is not given an option.

Enable interrupts for all processors within the specified processor set. See psradm(8). This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Display the processor set assignments for the specified list of processors. If no argument is given, the processor set assignments for all processors in the system is given.

Display the processor set bindings of the specified processes or of all processes. If a process is composed of multiple LWPs which have different bindings and the LWPs are not explicitly specified, the bindings of only one of the bound LWPs is displayed. The bindings of a subset of LWPs can be displayed by appending "/lwpids" to the process IDs. Multiple LWPs may be selected using "-" and "," delimiters. See EXAMPLES.

Display the LWPs bound to the specified list of processor sets, or all LWPs with processor set bindings.

Remove a list of processors from their current processor sets. Processors that are removed return to the general pool of processors. Processors with LWPs bound to them using pbind(8) can be assigned to or removed from processor sets using the -F option. This option is restricted to users with the PRIV_SYS_RES_CONFIG privilege.

Remove the processor set bindings of a subset or all the LWPs of the specified processes, allowing them to be executed on any on-line processor if they are not bound to individual processors through pbind. Users with the PRIV_SYS_RES_CONFIG privilege can unbind any process or LWP from any active processor set. Other users can unbind processes and LWPs from processor sets that do not have the PSET_NOESCAPE attribute set. In addition, the user must have permission to control the affected processes; the real or effective user ID of the user must match the real or saved user ID of the target processes.

Removes the bindings of all LWPs bound to the specified list of processor sets, or to any processor set if no argument is specified.

Specify pid as a process ID.

The set of LWPIDs of the specified process to be controlled or queried. The syntax for selecting LWP IDs is as follows:

2,3,4-8 LWP IDs 2, 3, and 4 through 8
-4 LWPs whose IDs are 4 or below
4- LWPs whose IDs are 4 or above

Specify processor_id as an individual processor number (for example, 3), multiple processor numbers separated by spaces (for example, 1 2 3), or a range of processor numbers (for example, 1-4). It is also possible to combine ranges and (individual or multiple) processor_ids (for example, 1-3 5 7-8 9).

Specify processor_set_id as a processor set ID.
