Automating synchronization
We can configure more than one WebSEAL server in the environment. The term cluster refers to a group of WebSEAL servers configured to work together. We can use WebSEAL clusters to automate the synchronization of configuration information between different WebSEAL servers. Clustering can also improve system availability and performance. All cluster members must be the same server type. The WebSEAL server type for the cluster is either a:
- WebSEAL running on appliances.
- WebSEAL running on standard operating systems.
In a clustered environment, we must nominate a master server that is responsible for all cluster configuration changes. The remaining servers in the cluster are designated as slaves.
Whenever a slave is restarted, it checks the configuration information about the cluster master. If the slave's internal configuration information is not up to date then the slave automatically synchronizes with the master. We can synchronize all servers in the cluster by using the cluster restart server task command.
