c
Always back up the /site/config file before making any changes.
See “Changing the Configuration File” in Chapter 11 of the iNEWS
Newsroom Computer System Operations Manual for more information.
Changing the
configuration file
requires the use of ed ,
the UNIX line editor.
See Chapter 10 of the
iNEWS Newsroom
Computer System
Operations Manual for
more information.
a. At the console, select all iNEWS Servers. Instructions for how to
do this is provided in Chapter 2 of the iNEWS Newsroom
Computer System Operations Manual.
b. Use the ed command to open and edit the configuration file, by
typing:
ed /site/config
1259
After you press Enter, the editor responds by displaying a number,
as shown, indicating the file size expressed as the number of
characters, including spaces and returns.
c. Add the monitor server’s device number to the servers line in
the host definition for the iNEWS Server that will run the monitor
server program. For instance:
servers 261 263 265 267
The device number 267 is added to the servers line in this
example.
n
Divide your server programs evenly among your iNEWS Servers to
distribute the load they put on your system. For instance, put odd
numbered programs on server A and even numbered ones on server B.
Additionally, ensure that you also add the configuration line for the
monitor server to alternate host definitions for your iNEWS Servers. This
ensures it can run on the surviving computer should one of your iNEWS
Servers stop functioning. A sample configuration file is provided in
AppendixB; it includes pointers indicating where in the file information is
added, as described in this procedure.
