System Profile Files
256
Sample system profile files are in “System Files” on page 535. The most important of these
profile files is the system profile(/site/system), which is discussed in the sections that follow.
When you start your system, each server reads its copy of the system profile and incorporates the
material into its operation.
An example of the system profile is provided on page 248.
The system
profile contains several parameters. Each parameter begins with an identifying
keyword, followed by an equal sign (=) and the parameter’s value. When an iNEWS Server reads
its system profile, it finds each parameter’s value by searching for the keyword that represents
that parameter. If the server searched the system profile in the example on page 248, it would
f
ind that NRCS was the parameter associated with the keyword, id.
Most, but not all, parameters have default values the system uses if the parameter is not present
in the system profile. Consequently, a system profile usually includes only parameters you want
set differently from their default values, and those that have no default values and must be set in
the system profile. Your system profile may not contain the same parameters as the example.
Changing the System Profile
System profile parameters are configured in the system when servers are connected. After the
system profile in /site/system is modified, the system should be rebooted and reconnected to get
the servers to read the modified system profile. The following sample procedure lets you change
the localtimeout parameter in your system profile.
To change your system profile at the console:
1. From the PuTTYCS application, select the PuTTY Filter created for sending server
commands to all servers, such as iNEWS Consoles.
2. Type:
ed /site/system
n
This procedure, which modifies the /site/system file uses ed, the line editor. If you do not know
how to use ed to modify lines in the file, please see “The Line Editor, ed” on page 647.
A message similar to the following appears:
editing /site/system

3. Find the line that contains the localtimeout parameter, such as:
localtimeout=45:00 remotetimeout=30:00
4. Change the 45:00 value for that parameter to 15:00:
localtimeout=15:00 remotetimeout=30:00
5. Type w to write (save) your changes to disk.
