5.2.2.  sysApplElmtRunTable and sysApplElmtPastRunTable

   While the sysApplRunTable and sysApplPastRunTable focus on
   applications as a whole, the sysApplElmtRunTable and
   sysApplElmtPastRunTable provide information regarding an
   application's executable elements, (processes), which are either
   currently executing or have executed in the past.

   The sysApplElmtRunTable contains an entry for every process currently
   running on the host.  An entry is created in this table for each
   process at the time it is started, and will remain in the table until

   the process terminates.  Note that in order to provide complete
   information on the load on the system, this table lists EVERY running
   process, not just those processes that are running as part of an
   identified application.  However, when processes terminate, only
   information from entries corresponding to elements of an identified
   application are moved to the sysApplElmtPastRunTable.

   The sysApplElmtPastRunTable maintains a history of processes which
   have previously executed on the host as part of an application. When
   a process from the sysApplElmtRunTable terminates, the entry's
   information is moved to this sysApplElmtPastRunTable provided that
   the process was part of an identified application.  If the process
   cannot be associated with any 'parent' application, then it is simply
   removed from the sysApplElmtRunTable.  This allows for processes like
   'ps' or 'grep' to show up in the sysApplElmtRunTable, (where they are
   consuming resources and are thus "interesting"), but not in the
   sysApplElmtPastRunTable.

   Because the sysApplElmtPastRunTable will continuously grow as
   processes are executed and terminate, two scalars are defined to
   control the aging-out of table entries.  The value of
   sysApplElmtPastRunMaxRows specifies the maximum number of entries the
   table may contain, while the sysApplElmtPastRunTblTimeLimit specifies
   the maximum age of the table entries.  Oldest entries are removed
   first.

5.3.  System Application Map Group

   The System Application Map group contains a single table, the
   sysApplMapTable, whose sole purpose is to provide a backwards mapping
   for determining the invoked application, installed element, and
   installed application package given a known process identification
   number.
