Determine minimum limits

Using the formulas shown earlier in this chapter and the criteria stated at the beginning of this section, we can determine the resource usage that must be accommodated.
  • Address space count - maximum

    4 + 2*A + N*(x) + (2 + N*0.01)

    4 + 2*20 + 500*(1) + (2 + 500*0.01) = 551

  • Address space count - per user

    x

    1

  • Process count - maximum

    6 + 3*A + N*(x + z) + (10 + N*0.05)

    6 + 3*20 + 500*(2 + 0) + (10 + 500*0.05) = 1081

  • Process count - STCRSE

    6 + 3*A

    6 + 3*20 = 66

  • Process count - per user

    (x + z)

    (2 + 0) = 2

  • Thread count - RSE thread pool

    14 + Np*(19 + x + z) + (20 + Np*0.1)

    14 + 25*(19 + 1 + 0) + (20 + 25*0.1) = 536

  • Thread count - JES Job Monitor

    4 + N + (20 + N*0.1)

    4 + 500 + (20 + 500*0.1) = 574

  • User IDs

    500 + 2 = 502

    The 2 extra user IDs are for STCJMON and STCRSE, the z/OS® Explorer started task user IDs.
