/IDENTIFICATION=pid

    Requires GROUP or WORLD privilege for processes other than your
    own.

    Specifies the process identification (PID) value of the kernel
    thread for which characteristics are to be changed. The target
    process must be on the same node as the process from which the
    command is issued. The /IDENTIFICATION qualifier overrides the
    process-name parameter.

    The PID is assigned by the system when the process is created.
    When you specify a PID, you can omit the leading zeros.

    If you use the /IDENTIFICATION qualifier, the process-name
    parameter is ignored.

                                   NOTE

       The /IDENTIFICATION qualifier allows the SET PROCESS command
       to affect individual kernel thread PIDs; because each thread
       is a separate runnable entity, this command treats them as
       discrete entities in terms of affinities and capabilities.
