3. The second intermediate system executes the third ROUTE command and sends
the command string SHOW USERS to the target system through LINK3.
4. The target system executes the SHOW USERS command.
There is no limit to the number of systems that may be traversed in this way.
However, to route commands through multiple intermediate systems, your user ID
must be configured on every intermediate system for both logon TO and logon FROM
remote system access.
You may find it helpful to set up an EQUATE to assign a lengthy routing scheme to a
simple character string. For example:
EQUATE L3 ROUTE LINK1 ROUTE LINK2 ROUTE LINK3+
Because in a purely Tandem network all intermediate nodes are logically connected by
using the DEFINE LINKS command, it is possible to shorten the original command
string to:
ROUTE LINK3 SHOW USERS
NonStop NET/MASTER MS provides this automatic routing feature.
Monitoring Events
From Remote Systems
Messages flowing through INMC links (both inbound and outbound) can be enabled
or disabled. The Inter-System Routing (ISR) component of NonStop NET/MASTER
MS controls the routing of messages over NonStop NET/MASTER MS, SOLVE
management services, and NetView INMC links in a network.
Enabling and disabling the flow of EMS, solicited, and unsolicited messages between
INMC links with the ISR command is discussed in the NonStop NET/MASTER MS
System Management Guide.
Whether messages actually flow between two systems depends upon the mutual ISR
settings on both systems. For example, if your local system expects to receive inbound
unsolicited messages from a remote system, the remote system must be allowed to
send outbound unsolicited messages to your system.
If your local system has been set to receive unsolicited messages from remote systems,
these messages are delivered to all users configured to receive EMS messages.
To display information about the ISR definitions for all active links, issue a SHOW ISR
command. Refer to the NonStop NET/MASTER MS Command Reference Manual for
more information on this command.
Remote Message Display The way remote messages are displayed on your terminal is defined by your system
manager as part of the link-definition procedure. Remote messages can be identified
by background color, text color, highlighting, and message identifiers.
Non-Roll-Delete Messages
From Remote Locations
Non-roll-delete messages originating from remote locations are displayed and handled
the same as locally generated NRD messages.
If a link fails, all NRD messages that originated from the remote system are
automatically deleted.
