Notifications
Notifications include process alarms, system alarms, messages and journalled
events. With the Distributed Server Architecture option, alarms and messages are
distributed as needed by the processes running on each server in the system.
Alarms
On each server, you enable alarms from remote servers by configuring the areas
for which you want to display alarms and then enabling alarms for those areas.
This process is the same as for alarms from the local server.
Operators use the System Configuration - Areas display if they want to identify
the server for points that are in alarm.
An alarm is also displayed if a remote server cannot be accessed. See
“Performance Considerations” on page 348 for details.
For information about the different effects of disabling alarms for local and
remote areas, refer to “Disabling Alarms in a Distributed Server Architecture” on
page 343.
System Alarms
If you need to display system alarms for one server on another server, you need
to configure Area Code 1 on the server that issues the alarms. This is good
practice for all servers that share data.
To configure Area Code 1, you log on to the server that issues the alarms, open
the System Configuration - Areas summary, and enter an area code for the System
Area at the top of the page. For details, refer to “Defining and Enabling Areas” on
page 92.
Disabling Alarms in a Distributed Server Architecture
In a distributed server architecture, the effect of disabling alarms depends on
whether they are for points in a local area or a remote area.
Alarms for a Local Area
If you disable alarms for a local area, the alarms are not generated. Subscribing
servers receive the alarm message “Notification Area Unavailable Area Code”.
