Routing to Self-Locating Consoles

      Disclosed is a mechanism for delivering system messages to the
operator on the console that is the most convenient for the operator
based on the operator's location within the physical installation.

      Today, the system operator may need to walk to a specific
console to perform certain specialized functions.  The disclosed
mechanism eliminates that requirement.

      The mechanism is described as applied to the MVS/ESA* disabled
console communications (DCC, a.k.a.  Branch-Entry Synchronous Write
to Operator (WTO)), but is applicable to any type of message routing
to stationary consoles.

      The operator is to be equipped with a beeper/transmitter that
is also used as a locating device for the system to determine the
operator's position in the building.

      The system is to be aware of the position of ALL
locally-attached (i.e., attached directly to the system via a control
unit (CU), as opposed to network (e.g., SNA) attachment) consoles and
the system (service processor) console in the area where the operator
is using a device self-location technique which allows the system to
be aware of the physical location of all of its consoles.  The system
must also be aware of the layout of the building where the consoles
are located.

      When a problem occurs and the system needs to communicate with
the operator to resolve the emergency, the following steps will be
performed:

1.  The system locates the operator using the self-locating beeper
    he/she carries.

2.  The system examines the I/O definition tables to determine the
    set of useable console (i.e., those that are locally attached and
    have dedicated control units (the MVS Disabled Console
    Communications Facility (DCCF) has a restriction of communicating
    only to consoles that do not share their control units with other
    consoles)).

3.  Using the operator coordinates and building layout, the system
    determines the console (preferred) that is easiest to reach from
    the operator's present position from among the set of consoles
    derived in the previous step.

4.  The system resets the I/O interruption subclass of the preferred
    console and all the other useable consoles in the operator's
    proximity to that used for emergency communications, preserves
    the consoles' screen buffers' contents, and displays an
    "emergency message" logo.

5.  The system sends a signal to the operator's beeper to attract the
    operator's attention.  The beeper LCD (liquid crystal display)
    displays the identifier of the preferred console determined in
    the previous step, which the system would like to use for
    emergency message processing.

6.  The operator finds the console recommended by the system or any
    other console nearby that is displayin...
