/sys$common/syshlp/helplib.hlb SET, PROCESS, Examples  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    1.$ SET PROCESS/PRIVILEGE=EXQUOTA

      The SET PROCESS command in this example assigns the current
      process the privilege of exceeding quotas.

    2.$ SET PROCESS/NORESOURCE_WAIT

      The SET PROCESS command in this example disables resource wait
      mode for the current process.

    3.$ RUN/PROCESS_NAME=TESTER  CALC
      %RUN-S-PROC_ID, identification of created process is 0005002F
      $ SET PROCESS/PRIORITY=10  TESTER

      The RUN command in this example creates a subprocess and gives
      it the name TESTER. Subsequently, the SET PROCESS/PRIORITY
      command assigns the subprocess a priority of 10.

    4.$ SHOW PROCESS/SUBPROCESS

      19-APR-2001 15:17:28.41  User: DAVIS Process ID:   31900218
                               Node: OCALA  Process name: "DAVIS"

      Processes in this tree:

      DAVIS *
        DAVIS_1
        DAVIS_2

      $ SET PROCESS/SUSPEND DAVIS_1
      $

      The SET PROCESS/SUSPEND command in this example suspends the
      process DAVIS_1 such that ASTs can be delivered to it. Because
      no keyword was specified, the /SUSPEND=SUPERVISOR version is
      assumed.

    5.$ SHOW PROCESS/SUBPROCESS OCALA::TESTA

      19-APR-2001 12:17:24.45   User: TESTA    Process ID:   31400208
                                Node: OCALA    Process name:  "TESTA"

      Processes in this tree:

      TESTA *
        TESTA_1
        TESTA_2
      $ SET PROCESS OCALA::TESTA_2 /SUSPEND=KERNEL
      $

      The SET PROCESS/SUSPEND=KERNEL command in this example suspends
      the process TESTA_2 on node OCALA such that no ASTs can be
      delivered to it.

    6.$ SET PROCESS CPUSCHED/AFFINITY/SET=1/PERMANENT
      $ SET PROCESS CPUSCHED/CAPABILITY/SET=8/PERMANENT
      $ SHOW CPU/FULL

      In this example, CPU 1 has user capability 8 enabled (user mask
      of process CPUSCHED, and CPU affinity is set to 1. Either of
      these settings forces the initial kernel thread to run only on
      CPU 1, as shown by the SHOW PROCESS command.

      Then, the SET PROCESS/NOAFFINITY/NOCAPABILITY command clears
      all CPU affinities and user capability requirements for the
      initial kernel thread of process (CPUSCHED), and the binding to
      CPU 1 disappears.
