Abstract

A method by which the system operator or administrator can notify all attached users across multiple LANs which may not be connected to one another of events which affect them. This method enables a new command which allows the host file server (VM/LFS) administrator or operator to send informational messages to all attached users or any selected subset of attached users.

Method for Message Notification to Active Workstation Users for a
Host-Based Lan Server

      A method by which the system operator or administrator can
notify all attached users across multiple LANs which may not be
connected to one another of events which affect them.  This method
enables a new command which allows the host file server (VM/LFS)
administrator or operator to send informational messages to all
attached users or any selected subset of attached users.

      A method is needed by which a Workstation LAN File Services/VM
(WLFS/VM) administrator on a VM system can notify all LAN workstation
users attached to Workstation LAN File Services/VM that some event
was going to occur.  The users may be on distinct LANs whose only
point of commonality is Workstation LAN File Services/VM.  For
example, when operator shutdown of the file server was imminent,
there needs to be a way to contact user of the file server and
request they terminate their work and connections with the file
server.  The file server may be connected to multiple LAN which are
not interconnected.  A broadcast message on a LAN is not appropriate
because workstations may be attached to a LAN without being attached
to a particular server.

      The file server uses a Front End Processor (FEP) to connect to
a LAN.  The FEP is a surrogate for the LAN server on the network that
it is attached to.  The FEP does initial processing of LAN request
and then forwards those requests to the LAN server.  The FEP may
communicate with the LAN server through path distinct from the LAN it
is serving.

      The file server maintains tables of the active users and which
FEPs they are connected through.  The FEPs can each get the names of
active users.  These tables can be indexed by FEP or by the user.
These functions are necessary to implement the method.

      For broadcast messages the file server sends a command to each
FEP instructing it to se...
