6.1.5 Online Node Dialog Box
If you close the Configuration File menu and click on
the Nodes icon on the MGR program toolbar, you
will see what appears in Figure 10.
This indicates the node number and the associated
group flat file name associated with the node cur-
rently online.
The Configuration File window still indicates the system as
being online. You must close the Configuration File
window and cycle the Filter Sys icon on the
MGR toolbar to update system
information.
A CAUTIONARY NOTE
Be aware when looking at secondary
window dialog boxes. The
Online
Nodes
box and the
Configuration Files
box,
for example, are windows that are not dynami-
cally updated by the MGR program whenever ad-
ditional changesother than the one currently
postedhappen in the online environment. The
SysWindow
of the MGR program, however,
is
dynamically updated.
To show this, look at the diagnostic screen of Fig-
ure 7. If you exit the program with a
Ctrl + Q
key
combination, the diagnostic program ends and
you immediately revert to the system prompt.
At the same time, on the external PC containing
the MGR program, the
SysWindow
mirrors the
off-line status as shown in Figure 11. It is dynami-
cally updated. On the other hand, the
Configu-
ration Files
subwindow still indicates that the
system is Online. It is not dynamically updated.
The same is also true of the
Nodes Dialog
box,
if you were to look at it.
To update the
Configuration File
box or the
Nodes Dialog
box to reflect the current state
of online status, you must close their respective
windows and perform the following step:
Click on the
Filter SYS
icon on the MGR tool-
bar. Clicking on this icon opens up the
Message
Mapping
window. Opening and closing this win-
dow causes an update of system information be-
ing reported to the MGR program.
It is best to think of the information contained in
these subwindows as snapshots of the state of
the system at the time they are opened.
