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