Workstation Performance Stimulator

      This article describes a workstation device simulator
that was created to enhance the ability to perform total system tests
without using 5250 displays and printers.

      The Work Station Performance Simulator (WSPS) provides
simulation for both printers and displays that can currently be
attached to the local workstation controller on the S/36, S/38, and
AS/400*.  The simulator is based on the IBM 5259 Migration Data Link
product hardware.  The functional microcode of the 5259 is replaced
with the specially developed microcode for the WSPS.  5259 hardware
does not require any changes to support the WSPS simulator.  Any
required maintenance of the hardware can be performed by an IBM
Customer Engineer.

      The WSPS can simulate up to 14 workstations for each 5259 in
the standard configuration.  Modifying the hardware results in a WSPS
version that can support up to 28 devices. This is accomplished by
modifying the original hardware and adding an additional logic board.
Both of these units can be mounted in standard AS/400 racks.  One
rack can contain up to 10 units for a maximum of 280 simulated
devices.

      The simulator has the following major functions:
    -  WSPS provides built-in display and printer simulations that
closely mimic the currently available devices.  These simulations
exist as factory defaults within the simulator.  In most cases, these
simulations are adequate to satisfy the typical testing scenario.
   -  NVRAM within the 5259 provides the ability to save special
configurations created by the user.  The user can modify the factory
default values to tailor the simulation to their own testing needs.
Once created, these are saved for a turn-key operation.
 -  The user can customize unique device simulations that can be used
for testing purposes or for future device support.  The simulator
provides the user with the ability to create unique device responses.
This function was created as a means to support future workstations.
The useful life of the simulator can be extended with this function.
