The EMSPROC procedure determines which events are passed on to the following
three NonStop NET/MASTER MS components:
The NCL log procedure (referred to as the LOGPROC procedure) that is
configured with the SYSPARMS LOGPROC command for your system. A
LOGPROC procedure intercepts and processes messages destined for the NonStop
NET/MASTER MS activity log.
The NCL message procedure (referred to as the MSGPROC procedure) associated
with your current OCS window. If you have a MSGPROC procedure assigned to
your OCS window, it processes all messages directed to your OCS window.
The MSGPROC procedure analyzes the message content and takes appropriate
action. Functions available to this procedure include the ability to delete
messages, modify the message text, and issue internal commands as a result of a
message.
Each operator may have different MSGPROC procedures to process messages in
different ways or may have different MSGPROC procedures operating in different
OCS windows.
If you have a default MSGPROC procedure specified in the Message Procedure
field of your user ID definition record, it is invoked automatically when you enter
OCS. You can terminate execution of the current MSGPROC procedure by using
the PROFILE MSGPROC=FLUSH command, and explicitly start up a different
MSGPROC procedure by using a PROFILE MSGPROC command (refer to the
NonStop NET/MASTER MS Command Reference Manual for details). (The different
MSGPROC procedure is only active for the current OCS session: if you exit from
and return to OCS, the default MSGPROC procedure is again invoked
automatically.)
The NonStop NET/MASTER MS Inter-System Routing (ISR) component for
routing messages to other NonStop NET/MASTER MS or NET/MASTER nodes
(see Section 8, “Communicating With Remote Systems,” for more information on
the ISR component of NonStop NET/MASTER MS).
EMSPROC, LOGPROC, and MSGPROC procedures are discussed in detail in the
NonStop NET/MASTER MS System Management Guide and the NonStop NET/MASTER
NCL Programmer’s Guide.
