Process Scheduler States?

» close window

The Question is:

 
How many process states VAX has? What are they? Thank you
 

The Answer is :

 
  A trick question?  A VAX has no process states, as it is hardware.
 
  OpenVMS VAX has various states within the process scheduler, and the
  OpenVMS Wizard would suggest reviewing the Internals and Data Structures
  Manual for details of the following scheduling states:
 
literal SCH$C_COLPG = 1;                ! COLLIDED PAGE WAIT
literal SCH$C_MWAIT = 2;                ! MUTEX AND MISCELLANEOUS RESOURCE WAIT
literal SCH$C_CEF = 3;                  ! COMMON EVENT FLAG WAIT STATE
literal SCH$C_PFW = 4;                  ! PAGE FAULT WAIT
literal SCH$C_LEF = 5;                  ! LOCAL EVENT FLAG WAIT
literal SCH$C_LEFO = 6;                 ! LOCAL EVENT FLAG WAIT OUT OF BALANCE SET
literal SCH$C_HIB = 7;                  ! HIBERNATE WAIT
literal SCH$C_HIBO = 8;                 ! HIBERNATE WAIT OUT OF BALANCE SET
literal SCH$C_SUSP = 9;                 ! SUSPENDED
literal SCH$C_SUSPO = 10;               ! SUSPENDED OUT OF THE BALANCE SET
literal SCH$C_FPG = 11;                 ! FREEPAGE WAIT
literal SCH$C_COM = 12;                 ! COMPUTE, IN BALANCE SET STATE
literal SCH$C_COMO = 13;                ! COMPUTE, OUT OF BALANCE SET STATE
literal SCH$C_CUR = 14;                 ! CURRENT PROCESS STATE
