Deployment Guide
Replicating the database contents ensures that in the event of a primary node failure, the secondary node is
up to date and can continue to deliver the same network services to clients. While the primary node is
online, the secondary node’s database can only be updated with replication changes from the primary node.
No other database changes can take place on the secondary node. Because of this, any form that requires a
database update will be disabled and shown as “Read Only Access” on the secondary node.
Ensure that you always access the cluster using the virtual IP address when performing any database
updates, such as creating new guest accounts or performing RADIUS authentication. This is required so
that the changes will be performed on the primary node and then replicated to the secondary node.
Configuration Replication
Configuration replication
also occurs continuously within the cluster, but takes place at a slower rate
due to the reduced frequency of configuration updates. This rate is the Config Sync rate specified in the
cluster configuration, which by default is once every minute.
The configuration items that are replicated include:
Configuration for installed plugins (
See
“Configuring Plugins”
in the Administrator Tasks chapter)
Fields defined in Guest Manager ( See
“Customization of Fields”
in the Guest Managment chapter)
Forms and views defined in Guest Manager (
