Device Exerciser Having Multiple Exit Options, Including a Lock Option

      This article describes an exit option which "locks" an
application in a secure mode.  It allows current operations to
continue executing but locks out any attempt to start, stop or change
operations.  The application is essentially placed in browse-only
mode.

      Certain applications require the ability to start execution and
then exit and provide a method to have the operations continue but
not allow any changes in execution of the operations.  The AS/400*
Device Exerciser is one of these applications.  The service
representatives need a method to start the operation, exit and return
at a later time or date to view the results of the exerciser.

      The Device Exerciser uses the LOCK option to provide this
function.  The Device Exerciser Exit screen shown in the figure
illustrates the lock option (option 2).

      If the LOCK option is chosen, any active device exercisers will
continue to run.  After this option completes, you can start the AS/
400 Device Exerciser and display the results.  However, device
exercisers cannot be started, stopped, or changed in this mode.

      The lock mode is accomplished by the steps in the following 3
phases of execution.
-  LOAD THE PROGRAM.  During the loading of the Device Exerciser on
the system, a program is restored into a temporary library.  This
program is saved separately on the distribution tape, i.e., it is not
saved with the rest of the Device Exerciser library.  This program is
then run during the load process and removed from the temporary
library.  This program creates an object with a unique name which
contains a unique key.  If the service representative signs off the
system, both the key and the temporary library are removed from the
system.
-  START-UP THE PROGRA...
